List and describe the different types of standpipe systems.

A wet standpipe has an automatic and dedicated water supply, so the water is in the pipes at all times and is ready for immediate use by fire fighters. An automatic dry standpipe is a system of piping typically filled with pressurized air. Upon the opening of a hose valve, the air pressure drops to a level that permits a device, such as a dry pipe valve, to activate and allow the water to flow into the piping network. A semiautomatic standpipe is a system in which the piping network is filled with pressurized or atmospheric air. Upon activation of an initiating device that is located near the hose valve, a deluge or dry pipe valve operates, allowing water to flow into the piping network. A manual standpipe is a system in which the water in the piping network is typically supplied by a domestic source that is incapable of providing the required system pressure and flow demand, but maintains water to the system to improve performance. A manual dry standpipe is a system that has no water source and requires connection to a water source in order for water to flow through the piping network. (Ch. 6 Review)

By interfacing with other building, control, and suppression systems, this arrangement can provide overall management of a building during a fire emergency by providing manual and automatic system command and monitoring capabilities. (Ch. 4 Review)

How can a person confirm that the post indicator valve to the building fire sprinkler system is open?

By looking at the valve window that shows the word "OPEN" or "SHUT" By removing the valve handle, operating the valve, and observing the water discharge out of the main drain (Ch. 5 Review)

How can a person confirm that a gate-type street valve is fully or partially opened or closed?

By using a street key to turn the valve and observe the effect on the amount of flow from the fire hydrant (Ch. 5 Review)

What is the purpose of calculating fire flow for a particular location? Should reductions in the calculated fire flow be permissible if a partial or full fire sprinkler system protects a structure?

Calculating the needed fire flow provides an estimate of the number of gallons needed to fight a fire (manually) at a particular location. Once the number is determined, the water purveyor analyzes the water system to determine if the system is capable of meeting the needed fire flow or requires infrastructure improvements. Full reductions are not practical since fire sprinkler systems are designed to control fires, not necessarily extinguish them. If the fire is not out upon arrival of the fire department, then additional water would be necessary to fight the remaining fire. In addition, the fire sprinkler system could fail to deliver any water before the fire department arrives. Partial reductions are more practical since properly designed, installed, and maintained systems will, in most instances, not only control but extinguish the fire. (Ch. 5 Review)

Which extinguishing agent is effective on Class B and C fires, but has limited use on Class A fires?

Carbon dioxide (pg 288)

________ are used to prevent water from flowing out of the fire protection system back into the water supply system.

Check valves (pg 112)

Name and describe the different types of valves used to control the water flow in a water supply network.

Check valves permit water to flow in one direction by use of an internal hinged disk or plate called a clapper. When the source water pressure is greater on the supply side, the clapper opens; when the pressure equalizes, the clapper shuts. However, check valves offer little protection against water supply contamination. Backflow prevention devices operate in a similar manner as the check valve but in many cases have two independent check valves that prevent backsiphonage or backflow. Some even have the ability to dump the water out of the backflow device so there is no possibility of a backsiphonage or backflow condition occurring. (Ch. 5 Review)

Which of the following classes of fire involves ordinary combustibles such as cloth, grain, paper, rubber, and wood?

What problems are created when a fire alarm system experiences false alarms?

False alarms remove resources from service and can delay response to a legitimate fire. Repeated false alarms can change human behavior when people stop responding to alarms because they do not think the alarms are legitimate. (Ch. 4 Review)

When determining the water supply demand for a water-based fire protection system at a particular location, what role does the fuel load play?

Fuel load determines the amount of water that is necessary to control a fire at a particular hazard. The water supply is one of the most critical factors when designing a water-based fire protection system. The greater the fuel load, the greater the water supply demand. The water supply must have adequate pressure, flow, and duration for the intended hazard, and any deficiency will result in a system that may not perform as needed. Many water supplies are inadequate for the fuel load, and without a supplemental water supply, a fire could quickly overwhelm the fire protection system. (Ch. 5 Review)

Which of the following extinguishing agents forms a vapor barrier between the Class B fuel and the atmosphere, thus cooling and smothering the fire?

Foam (pg 288)

What are the differences between foam, foam solution, and foam concentrate?

Foam is a mixture of foam concentrate, water, and a gas, typically air, that when combined in the correct proportions, produces air-filled bubbles to smother, isolate, and cool two-dimensional flammable and combustible liquid fires or fills an area to create a barrier. Foam concentrate is a condensed form of the foam product, and a foam solution is the result of mixing foam concentrate and water in the correct proportions. (Ch. 8 Review)

Free burning stage (pg 9)

Installation of which type of fire department connection overcomes topography and distance from the hydrant problems?

Freestanding (Ch. 6 Review)

How does friction loss affect a water supply and what are some ways to overcome it?

Friction loss is a loss of hydraulic energy due to the resistance of the interior walls of the pipe and components that reduce the water pressure in the system. Typically, the water supply loses pressure as the water moves away from the source, and pressure levels at the farthest delivery points could be very low or nonexistent if the system design is inadequate. To overcome friction loss, engineers use large transmission and distribution mains, minimize the number of changes in directions water must flow, install pumps, and use materials that allow water to flow with less friction. (Ch. 5 Review)

What is friction loss and how does it affect the design of an automatic fire sprinkler system?

Friction loss is a progressive pressure drop when the flowing water makes contact with the piping and components in the water system. Pressure loss due to friction causes the designer to make changes to the design to compensate for the pressure loss. (Ch. 7 Review)

Why should heat detectors not be used in place of smoke detectors?

Heat detectors can be slower to initiate an alarm than other detectors are, especially smoke detectors. This is because they detect fires via the heat generated by the fire and not the smoke that forms before sufficient heat buildup. (Ch. 3 Review)

Discuss the different fire detector classification.

Detectors are classified by the component of a fire signature they detect: heat, smoke, flame, or gas.9. Why should heat detectors not be used in place of smoke detectors? (Ch. 3 Review)

Why do some insurance companies prefer a diesel driver to an electric driver?

Diesel drivers are considered more reliable because they are self-contained units that have batteries to start the motor and a fuel supply. (Ch. 5 Review)

List the types of fire and explain each.

Diffusion flame fire is usually the result of a combustible gas emitted by a burning material that mixes with the oxygen in the air surrounding the material. The gas, fuel, and oxygen move into the reaction zone of the flame from opposite sides and, once consumed, the fuel and oxygen combustion products spread out or "diffuse" from the flame. Smoldering is burning in which sufficient air flows over the surface area of the material, providing enough oxygen to sustain the slow combustion process although there is no flame. Spontaneous combustion or self-heating results when certain materials undergo oxidation in an environment that limits heat dissipation, causing the heat to remain in the area and increase the temperature to promote the reaction. Premixed flame is a process in which the fuel and oxygen mix before ignition or combustion occurs. (Ch. 1 Review)

Of the different piping used to make up a supply network, which type of piping supplies a number of smaller areas within the system?

Which NFPA standard, titled National Fire Alarm and Signaling Code, lists system classifications for fire alarm systems?

NFPA 72 (pg 77)

Was it appropriate to adapt the existing dry chemical extinguishing system to protect the new spray booth?

No, a design professional will need to evaluate the hazard and current system to determine the level of protection needed for each booth. (Ch. 9 Review)

In this situation, if electrically controlled/electromagnetically locked egress components substituted for access-controlled egress components, would the lack of any fire protection system make this a noncompliant system?

No; the codes do not require a fire alarm, fire detection, or fire sprinkler system when a person can make physical contact with the door hardware to unlock the door. (Ch. 13 Review)

Does the lack of any fire protection system make this a noncompliant installation?

No; the codes state that the access control system has to be connected and release upon activation only if there is a fire alarm, fire detection, or fire sprinkler system. (Ch. 13 Review)

Which components of a water spray fixed system are very important and available in automatic or open configurations?

Nozzles (pg 228)

Once an alarm activates, the elevators travel to the first floor or, if the alarm originates on the first floor, to an alternative floor so fire fighters can use them to investigate the alarm. (Ch. 4 Review)

Which of the following is the correct mixture for Halon 1211?

One part carbon, two parts fluorine, one part chlorine, one part bromine (pg 269)

Briefly explain the activation and operational sequence for wet and dry chemical extinguishing systems.

Operation of a wet or dry chemical system can be automatic or manual. For automatic activation, a fire must build to such a level that it activates an automatic sensing device such as a fusible link or heat detector located near or within the protected area. For manual activation, a person must make physical contact with the releasing device, such as a manual station, to start the extinguishing sequence. Once the control panel receives the signal from an automatic sensing device or manual activation device, a mechanical or electronic release starts a simultaneous operational sequence: the agent flows, control of the associated utilities takes place, and an alarm sounds. (Ch. 9 Review)

Discuss the purpose of performing operational, discharge, and functional inspections and tests on water-based fire protection systems.

Operational, discharge, and functional tests verify the system is capable of performing as designed and will operate when needed. Water-based fire protection systems are just like any other mechanical equipment; they break, wear out, leak, are subject to different environments, and need exercise. Without performing the inspections and tests, there is no understanding of the operational readiness of the system. (Ch. 8 Review)

What measurable characteristics of a water supply must be deemed sufficient before a fire protection system can adequately protect a hazard?

Pressure, flow, and duration (Ch. 5 Review)

Under what conditions is it appropriate to use private mode notification?

Private mode notification is appropriate for occupancies where the occupants are not physically or mentally capable of responding, or where their movement within a building is restricted. These include nursing homes, hospitals, prisons, and jails. In this arrangement, trained individuals receive the signal at a location within the facility then respond and implement emergency procedures to better manage the situation and avoid unnecessary movement of occupants. (Ch. 3 Review)

Remote supervising station fire alarm system (pg 80)

What are the differences between commercial application fire sprinkler heads and residential fire sprinkler heads?

Residential heads have a thinner heat-sensitive element than standard response sprinkler heads so that the thinner materials can absorb heat much more rapidly, leading to quicker activation and water application. The deflector on a residential head generates a high-on-the-wall discharge pattern to ensure response to fires for drapes, curtains, or other hanging decorations. In addition, residential sprinkler heads do not flow large amounts of water and can operate at lower pressures. (Ch. 7 Review)

Semiautomatic, manual dry, and automatic dry standpipes (Ch. 6 Review)

Fuel dispensers at service stations are equipped with signs that include instructions and safety warnings. Use the fire tetrahedron to explain the reasons for these warnings.

Service stations offer an environment where the elements of the fire tetrahedron can easily come together to start a fire. The purpose of these signs is to state specific warnings in an effort to reduce the possibility of the introduction of a heat source that could cause a chain reaction to sustain a fire. By not smoking, turning off the motor, not using a cell phone, and discharging static electricity, some of the likely heat sources are no longer available to ignite the fuel. (Ch. 1 Review)

Which of the following systems is NOT preferred, because problems with ground faults and short circuits may send false alarms or prevent transmission to the municipal center?

Shunt auxiliary fire alarm system (pg 82)

Smoldering/decay stage (pg 10)

Does it matter if the elevator lobby area door on the sixth floor does not close?

It does matter because the elevator lobby will not be a protected enclosure and will not provide an area of refuge. (Ch. 12 Review)

What is a density/area curve? How would the system designer use the density/area curve when designing an automatic fire sprinkler system?

It is a graph that establishes the relationship between the required amount of water flow from a sprinkler head (density) and the area that must be covered by the water for different hazard classifications. The designer would determine the hazard level, find the curve that represents the hazard, then choose the point on the curve that will work best for the design. (Ch. 7 Review)

Why is it important to perform periodic water flow testing on a water-based fire protection system after the system's installation?

It is important to perform testing to ensure the adequacy of the water available to supply the system demand, and to ensure the valves that supply the water to the system are open. (Ch. 5 Review)

In this particular situation, is it acceptable to mix the three different manufacturers' foam concentrates in the same tank?

It is likely the foam concentrate from Manufacturer A and Manufacturer B can be mixed, but it is unlikely Manufacturer C's foam concentrate is compatible. (Ch. 8 Review)

Should a manual fire alarm box be able to initiate an alarm that activates the smoke control system?

It is not prohibited, but if a manual fire alarm box is activated on a different floor or area of the building, it could cause confusion regarding the actual location of the fire. (Ch. 12 Review)

Why was the alarm barely audible or not heard at all on the 7th, 10th, and 14th floors of the building?

It is typical for the alarm in a modern high-rise building to only sound on the floor of origin, the floor above origin, and the floor below origin. (Ch. 4 Review)

What access system is used as a backup to the siren sensor if it fails to detect the siren?

Key switch (pg 330)

Large volume spaces (pg 308)

What does NOT factor into requirements for automatic smoke detection in assembly or business occupancies?

Level of exit discharge (pg 89)

What are the three major differences between the NFPA 13 system and the residential fire sprinkler systems that change the overall protection goals?

Life safety by reducing the system water supply requirements, creating a special type of sprinkler head, and placing the fire sprinkler heads in the locations where a fire is most likely to start, but not everywhere (Ch. 7 Review)

Under the NFPA's commonly used color coding system, which color is used for a hydrant that provides 1500 gallons per minute or greater?

Light blue (pg 118)

The fire sprinkler systems in the building were most likely designed based on what occupancy/hazard classifications?

Which carbon dioxide delivery system is primarily installed at industrial facilities for use by trained personnel and the fire department?

Standpipe/mobile supply system (pg 269)

Why are referenced standards so important to the code development process?

The code development community recognizes the necessity to look outside of their organizations in order for the model codes to cover all important and related issues thoroughly. This community therefore references documents published by other nationally recognized organizations that have specific knowledge and expertise to meet the required performance characteristic or design intent. The use of referenced standards ensures utilization and adoption of the best methods, standards, and practices. If all information were included as part of the model code documents, there would be an overwhelming and potentially unmanageable amount of information to review. (Ch. 2 Review)

What concerns do you have with dated inspection tags, tamper indicators, or seals affixed to the system?

Tags, indicators, and seals that are over 6 months old may be an indication the system is not being inspected, tested, or maintained when necessary (Ch. 9 Review)

Discuss the pros and cons of the ICC and NFPA code development process. Do you feel that each organization has adequate representation from all of the appropriate parties throughout the process and that each arrives at a true consensus? What suggestions would you make to improve each organization's methods?

The student should discuss how each process works, highlighting different types of participation (who can be involved and at what level, and who makes the initial and final decisions concerning code changes). In addition, the student should discuss the role of industry, professional organizations, trade associations, manufacturers, suppliers, code officials, consultants, and government agencies in the process and whether the process is too long or too short. (Ch. 2 Review)

In this situation, if the use and occupancy condition was assembly and delayed egress lock components were installed on the main entrance/exit doors, would this installation be code compliant?

The system is noncompliant if the adopted model code is NFPA 5000 because NFPA 5000 does not permit delayed egress components on the main entrance/exit doors in assembly use and occupancies. The system is noncompliant if the adopted model code is the IBC® because the IBC® does not permit this type of hardware in assembly use and occupancies. (Ch. 13 Review)

What is the most probable reason the old part of the building was not required to have an automatic fire sprinkler system installed when it was built?

The system was not required by code. (Ch. 2 Review)

Upon looking at a sprinkler head, how can the temperature rating be determined?

The use/occupancy conditions of the structure are the most important factor when determining installation requirements for a fire protection system in a structure. (Ch. 2 Review)

List and explain the various types of inspections and tests performed when accepting and maintaining wet and dry chemical extinguishing systems.

The visual inspection makes sure the components are the correct size, type, and material, and are in the correct location and orientation. The discharge and acceptance tests ensure that the wet and dry chemical systems discharge the appropriate amount of agent from the system nozzles and that all of the associated equipment operates properly. (Ch. 9 Review)

Why is it so important to have an accurate water flow test when designing a water-based fire protection system?

The water flow test provides the system designer with information concerning the pressure, flow, and duration of the water supply that is available for the hazard. Since the hydraulic calculations for the system design are based on the water flow test data, an inaccurate test could result in undersized or oversized piping, fittings, fire mains, and fire pumps; and a system that probably will not protect the hazard. (Ch. 5 Review)

When a foam concentrate container is labeled 1% or 3%, what does that signify?

This means the foam is usable on different hazards where one hazard only requires a 1% mixture, whereas the other requires 3%. (Ch. 8 Review)

Two-way emergency communication system (pg 84)

What should the occupants do if the alarms are not heard but the fire trucks can be seen and heard arriving at the building?

Unless occupants feel they are in danger, they should wait for instructions from the fire department. The fire department will provide information and instruction through the emergency voice alarm communications system. (Ch. 4 Review)

Why would fire alarms—but no voice instructions—have been heard on every floor in the much older high-rise buildings where some of the occupants previously resided?

Unlike today's modern high-rise buildings, most—if not all—high-rise buildings built before the mid-1980s only sounded a general alarm throughout the building; emergency voice alarm communication systems were not required when these buildings were constructed. (Ch. 4 Review)

What is the first factor used to determine any fire alarm installation requirements of a building?

Use and occupancy (pg 88)

What is the most probable reason the old part of the building was not required to install an automatic fire sprinkler system when the addition was built?

Use and occupancy did not change (Ch. 2 Review)

What is done to confirm that the design and installation meet the minimum standards and are consistent with the approved plans?

Visual inspection (pg 209)

Which system is a fixed fire protection system that discharges a very fine spray with water droplets that must be 1000 microns or less in size?

Water mist system (pg 230)

Why is it so important to have relief valves on a fire pump?

Water-based fire protection system components are rated for a maximum pressure, so to ensure that the rated pressure of the components is not exceeded, relief valves operate and relieve the excessive water and air pressure buildup associated with the operation of the fire pump.

Explain how wet and dry chemical systems control and extinguish fire.

Wet agents react with the fats and convert into a soapy foam blanket that covers the surface of the burning liquid fuel to smother and cool the liquid. Dry chemical agents cover and smother the burning material. (Ch. 9 Review)

Which of the following hydrant styles always has water in it for immediate use by fire fighters and is controlled by separate valves for each opening?

Wet barrel (pg 115)

Compare and contrast the different types of hydrants.

Wet barrel hydrant—Installed where the temperature is usually above freezing Dry barrel hydrant—Installed where the temperature drops below freezing Wall hydrant—Installed when it is difficult to locate a hydrant sufficiently away from a structure but where exposure to fire and falling debris is minimal Flush hydrant—Installed where barrier protection is not enough and the potential for damage is great Yard hydrant—Installed as part of a water supply system that can be supplied from a remote location and when access to a water supply is difficult (Ch. 5 Review)

Is it generally acceptable to mix three different manufacturers' foam concentrates in the same tank?

Yes, as long as the foam concentrate is the same type, has the same mixing ratio, and has been confirmed to be compatible by the manufacturer, they can be mixed. (Ch. 8 Review)

Is there any specific reason why Manufacturer C's Class A 3% foam concentrate should not be mixed with the other foam concentrates?

Yes, this foam concentrate is meant to work on ordinary combustible Class A fires, not on flammable and combustible liquid Class B fires. (Ch. 8 Review)

Is there a problem with the elevator doors staying open when they recall to the first floor?

Yes; because the elevator shaft is pressurized, leaving the doors open could allow too much air to escape, compromising the ability of the system to oppose the smoke and gases. (Ch. 12 Review)

In this situation, if delayed egress locks were substituted for access-controlled egress components, would the lack of any fire protection system make this a noncompliant system?

Yes; delayed egress systems require the building to have an automatic fire detection or automatic fire sprinkler system to deactivate the alarms. (Ch. 13 Review)

A wet or dry chemical system initiates a(n) ______ upon activation.

Ammonium phosphate is _________ in order to differentiate it from other dry chemicals.

yellow (pg 248)

What are some of the common myths and facts regarding automatic fire sprinkler system operation and performance?

· All sprinkler heads operate simultaneously. · Sprinkler heads activate for no reason. · The amount of water discharged will cause a flood or drown a person. · It costs more to repair water damage than fire damage. · Smoke detector activation will cause a sprinkler head to operate. The facts are: · Sprinkler heads operate independently and only the sprinkler head(s) in the fire area, not every head in a building, activate to control or suppress the fire. · Sprinkler heads undergo numerous tests by third-party testing and certification organizations such as Underwriters Laboratories and FM Global to ensure that the sprinkler heads maintain stability when standing ready to operate. It is rare that a sprinkler head accidentally activates unless the head has suffered mechanical damage, exposure to freezing conditions, or excessive heat. · Because sprinklers limit the spread of fire and smoke and in many cases extinguish the fire, the exposure to fire damage and smoke damage is limited. A manual hose stream will deliver 10 to 100 times more water than one sprinkler head during a fire event; this water could cause substantially more collateral damage. · The vast majority of smoke detectors operate independently of fire sprinkler systems and although there are smoke detectors that integrate with specialized fire suppression systems, they do not activate the sprinkler head, per se, but send a signal to a panel that releases water into the system. (Ch. 7 Review)

List the code requirements for delayed egress locks.

· Controlled doors must unlock upon activation of the automatic sprinkler or automatic fire detection system. · Controlled doors must unlock upon loss of power to the lock or locking mechanism. · Applying 15 pounds of force to the controlled door for 1 or 3 seconds (depending on the code) starts an irreversible process that must release the door in 15 seconds and sound an alarm at or near the door. (Note: If approved, the door can have a 30-second delay.) · Relocking the door is only by manual means. · A sign must be posted above and within 12 inches of the release device that instructs the occupant to push on the release device until an alarms sound and indicates whether it will open within 15 or 30 seconds. · There must be emergency lights at the door so the occupant can read the sign. · A signal to unlock the doors from a fire command center or a releasing mechanism located at the main entrance of the building is required. (Ch. 13 Review)

List and describe the three components of the means of egress.

· Exit access—Any useable space on any floor of a structure/building that a person uses to move toward the exit access, until that space reaches an exit. · Exit—An area such as an exit stairway or horizontal exit, built to protect people from a fire so they can safely leave the building or structure. · Exit discharge—The area outside of the exit door that the person uses to move away from the building until he or she reaches a street, alley, or other land leading to the street (Ch. 13 Review)

Name the three most widely used NFPA standards that deal with automatic fire sprinkler system design and installation and explain the application for each.

· NFPA 13, Standard for the Installation of Sprinkler Systems, is primarily for commercial and industrial properties. · NFPA 13D, Standard for the Installation of Sprinkler Systems in One- and Two-Family Dwellings and Manufactured Homes, is for home sprinkler systems. · NFPA 13R, Standard for the Installation of Sprinkler Systems in Low-Rise Residential Occupancies, combines elements of NFPA 13 and NFPA 13D to provide a fire sprinkler system that addresses the challenges associated with multi-occupant and multi-dwelling residential facilities. (Ch. 7 Review)

List and describe the three broad categories used to identify fire sprinkler heads.

· Old-style sprinkler head—A head where the water spray pattern developed by the deflector discharges water up and down, with 40% to 60% of the water flows initially downward · Standard spray sprinkler head—A head where all of the water spray pattern discharges down toward the floor, is characterized by a ½-inch orifice, and develops the umbrella or similar water distribution pattern · Specialty sprinkler head—A head with different physical characteristics than a standard spray sprinkler head where the head could have a smaller or larger orifice, a protective coating or special finish, a special frame and/or a deflector with a different and unique design for use with a specific installation or application (Ch. 7 Review)

Of the different methods of heat transfer, which is the transfer of heat from one body of material to another by direct contact?

Conduction (pg 11)

Why is it so important to ensure that the fire mains only supply water to fire protection systems and fire hydrants?

Connecting other systems (e.g., domestic water) on the same fire main could deplete the water supply for the fire protection system or hydrant. (Ch. 5 Review)

What are the differences between the containment, exhaust, and opposed airflow methods of smoke control?

Containment uses increased pressure to surround the fire area so the smoke and gas will not escape. Exhaust removes the smoke and gases from the fire area. Opposed airflow uses large amounts of air to move the smoke and gas in a particular direction. (Ch. 12 Review)

Which of the following forms of heat transfer occurs from one body to another through a medium such as a liquid or gas?

Convection (pg 11)

List and explain the differences between the different NFPA classifications for fire alarm systems.

Fire alarm system is the classification given to residential and commercial building (local) fire alarm systems. In the home, there can be single-station, multi-station, combination, and home fire alarm systems. The capabilities range from providing just an audible warning up to providing fire, security, and medical alerts. When dealing with commercial buildings, protected premises systems provide local audible and visual notification of a system problem, a supervisory problem, or a fire emergency, and may interface with other building systems and provide on- and off-site notification. The supervising station fire alarm system is the classification given to a fire alarm system in which signals are transmitted to a remote location where they are received and processed by trained individuals. Included in this category are proprietary supervising fire alarm systems. In these systems, a group of fire alarm systems at one location or multiple locations are under the constant supervision of the property owner's trained personnel, who monitor all of the owner's facilities' fire alarm system signals from a dedicated location. Also, central station service fire alarm systems are fire alarm systems in which all system functions and fire alarm signals automatically transmit to a central station facility that is staffed with trained, qualified, and proficient personnel who take the appropriate action to process, record, and respond to the signals and to maintain the systems being monitored. The remote supervising station fire alarm system transmits either directly to a public safety communications center via approved fire department radio frequencies, to a dedicated one-way (outgoing only) telephone line, or to dedicated communication circuits. If signals are not sent directly to a fire or public safety communications center, they are instead sent to an approved location where trained individuals monitor the signals at all times. The public fire alarm reporting system is the system that transmits alarms through circuits connected to a municipal communications center after an initiating device activates. The initiating device is typically a municipal fire alarm box or street box that is located on a street in the community. One-way emergency communications systems can propagate critical information to an individual, building, complex, and even an entire city by a number of different methods, including but not limited to texts, pages, emails, phone calls, emergency voice alarm communications systems, sirens, speaker arrays, and highway alert message boards. Two-way emergency communications systems permit first responders and, in some cases, building occupants a method of two-way communications within a building. The equipment is located in critical locations throughout the building to enable communication back to the fire command center. (Ch. 4 Review)

Define the terms fire and combustion and explain the difference between them.

Fire is a rapid oxidation process that produces varying degrees of heat, light, and flame. Combustion is a chemical reaction process in which a combustible material and an oxidizing agent produce heat or energy, along with other products that continuously sustain the process. The difference between fire and combustion is that in the combustion process, the released energy stays in the reaction to continue the reaction, whereas fire is a form of combustion that emits energy in the form of heat and light. (Ch. 1 Review)

Which type of lines tap off of distribution lines and directly connect to the water-based fire protection system or hydrant?

Discuss the different water supply systems that provide water to the supply network.

Gravity—A system in which the water source is at a higher elevation than the location it serves, thus eliminating the need for pumps because the water flows at a sufficient pressure Pumped—A system in which the water comes from a source at a lower elevation than the location it serves Combination gravity/pumped—A system that utilizes both gravity and pumps to manage the water supply3 (Ch. 5 Review)

Which system, if it has failed to shut down under fire conditions, will be the strongest contributor to smoke movement?

HVAC system (pg 310)

Under what circumstances should a dry chemical extinguishing system upgrade to a UL 300-compliant wet chemical extinguishing system? Name at least five reasons to require an owner of such equipment to replace the existing system.

If the appliances, location of appliances, and cooking medium change, then the suppression system installed to protect the operation should be upgraded because the agent and installation were not approved for the conditions. In addition, as manufacturers change their product line and the agents and equipment phase out, it will be problematic for the operator to maintain the equipment and suppression agent in compliance with original listing, installation, and approval because the replacements will not be listed or approved for the conditions unless tested as such, which is unlikely due to the cost. (Ch. 9 Review)

What two features that relate to stairway door operation are required in high-rise buildings, and why are they required?

If the doors are locked on the ingress side, provisions to unlock are required. In addition, an in-stair telephone or two-way communication located at every fifth level of a building or structure are required. The purpose of these features is to ensure that a person does not get trapped in the stairway. (Ch. 13 Review)

Where does the initial fire alarm signal sound in a modern high-rise building?

In a modern high-rise building, the initial fire alarm signal sounds on the floor of origin, the floor above the floor of origin, and the floor below the floor of origin. (Ch. 4 Review)

Which of the smoke control methods is best suited for a large volume space such as an atrium, and why?

In large volume spaces, there are no physical barriers so the smoke and gas will rise but possibly stratify if the space is tall enough. This condition makes the exhaust method the best because by supplying clean makeup air from below, the exhaust system can continue to pull the smoke and gas up and out of the structure. (Ch. 12 Review)

Discuss the similarities and differences between specialized water-based fire protection systems and standard fire sprinkler systems.

In many ways, there are few major differences between the four most prominent types of automatic fire sprinkler systems and the specialized water-based systems. All of these systems use water as the primary suppression agent, all must have an automatic water supply, all use the same or similar components, all must automatically activate, and in some instances, all of these systems use the same type of specialized system valve. Differences include some use of specialized spray nozzles instead of fire sprinkler heads, the integration of foam agents with water in certain types of systems, the use of specialized components, and the design and application methods.

Spontaneous combustion (pg 8)

What role do static and residual water pressures play in the design of a water-based fire protection system?

Static and residual water pressures provide the design professional with part of the information required to determine if the water supply is adequate to meet the demand. Based on this information, the design professional will determine what, if any, measures are necessary to improve the supply. (Ch. 5 Review)

_________ is defined as the pressure exerted on a water supply system when there is no water flowing.

Static pressure (pg 121)

List and describe the different classes of standpipe systems.

The Class I standpipe system is a system capable of supplying the required amounts of water at high pressure for manual firefighting purposes. The Class II standpipe system is a system that uses a small-diameter hose and nozzle attached to the standpipe so that building occupants, fire brigades, or fire fighters can fight small incipient-stage fires. The Class III standpipe system is a system typically equipped with a small-diameter hose and nozzle for trained building occupant use, but that is also capable of supplying the required water pressure and flow to support manual fire department suppression activities. (Ch. 6 Review)

dentify the two most prominent model code organizations that are leading the code development process.

The International Code Council and the National Fire Protection Association (Ch. 2 Review)

Why would a certifying authority request the "Record of Completion" before the actual acceptance test of a fire alarm system?

The Record of Completion holds the contractor responsible that the system installation is verified according to approved plans and will function as required, and that the system was inspected and tested by the contractor prior to the approving authority's acceptance test. (Ch. 4 Review)

Why is it so important to perform fire alarm system acceptance testing and periodic inspections and tests?

The acceptance test certifies that the system was installed as designed and approved, and operates as required. Failing to perform periodic inspections, tests, service, or maintenance of fire alarm systems, devices, or components can lead to unknown operational conditions and failure of the system. (Ch. 4 Review)

What is the air-to-water differential that governs the operation of dry pipe valves?

The air-to-water differential (ratio) principle states that a certain amount of water can be held back by a certain amount of air such as 5:1, where 5 pounds of water pressure requires 1 pound of air to keep the valve closed. The exposed surface area of the clapper valve determines the differential where the air side is larger than the water side. (Ch. 7 Review)

Why is the annunciation panel valuable to the responding fire personnel and building maintenance personnel?

The annunciation panel provides visible and valuable information (Ch. 3 Review)

What do the design density and remote area establish when designing an automatic fire sprinkler system?

The design density establishes that at a minimum, all of the sprinkler heads in the remote area must be able to deliver the stated minimum amount of water for the required amount of time. The remote area establishes the most hydraulically demanding part of the system. (Ch. 7 Review)

What are the design goals behind installing smoke control or management systems?

The design goals behind installing smoke control/management systems are to provide a tenable environment in the areas adjacent to the fire area for building occupants and fire fighters during a fire emergency, and to contain the smoke within its place of origin. (Ch. 12 Review)

What options are available to a fire protection system designer when it is determined that the water pressure is inadequate to support the design?

The designer can install gravity tanks, pressure tanks, or stationary fire pumps. (Ch. 5 Review)

Some smoke and fire doors are held open by magnets or other devices to allow easy movement from one part of a building to another, but upon activation of this function, which of the following happens?

The device holding the door open releases so the door can close to create a smoke or fire barrier. (pg 86)

What are the different elements of the smoke control acceptance test plan and why is it so important to perform annual smoke control system inspection and testing?

The different elements of smoke control acceptance include description of the smoke control systems, the design criteria, how these criteria will be demonstrated and proven, what will constitute successful performance, the step-by-step procedures and the test instrumentation, and the equipment that will be used in the process. Without annual testing, smoke control systems can rapidly fall into a state of disrepair or failed performance, particularly in multi-tenant office buildings during the initial build-out of first-generation tenants. Mechanical systems not only require exercising, but verification that reprogramming of the fire alarm system for new tenant alarm devices did not change the operation of the system, systems were not electrically disconnected due to nuisance operation, there were no failed damper motors, damper linkages were not intentionally disconnected, and no fan motors tripped on thermal overload. (Ch. 12 Review)

Who are the different individuals or organizations that should be present at the acceptance test of a smoke control system, and why?

The different parties that should be present at the acceptance test are the testing agent, engineer of record, approving authority, fire department personal, and the building owner's operating and maintenance personnel. The testing agent and engineer must be present to conduct the test, the approving authority to verify the results, and the fire department and building owner's operating and maintenance personnel to observe how the system operates and functions. (Ch. 12 Review)

What is the probable cause of the fire alarm signal continuing to sound?

The dry pipe sprinkler system pressure switch is holding pressure. (Ch. 3 Review)

What are the factors that contribute to the flashover stage of a fire?

The factors contributing to the flashover stage of a fire include the amount and type of fuel, the size of the room, the available air, and the manner in which heat is transferred within the fire area. (Ch. 1 Review)

__________ is/are considered to be the most important part(s) of any fire alarm system?

The fire alarm control panel (pg 40)

Why is the fire alarm control panel often referred to as the "brain" of the fire alarm system?

The fire alarm control panel is the point of interface between the system components. It monitors the integrity of the system circuits and devices; processes manual and automatic input signals from the initiating devices; drives the notification appliances; provides an interface to control or activate other fire protection and building systems in a fire emergency; and provides the power to support all of the system devices. (Ch. 3 Review)

Which function of a fire alarm system is caused by interfacing fire dampers with the fire alarm system to prevent propagation of smoke, hot gases, and flame?

The fire dampers close. (pg 87)

The fire triangle depicts the relationship between the three components (fuel, heat, and air) necessary for combustion, whereas the fire tetrahedron depicts the relationship between fuel, heat, air, and the uninhibited, chemical, or self-sustaining chain reaction necessary to sustain combustion. (Ch. 1 Review)

What are the differences between foam-water sprinkler systems and foam-water spray systems?

The foam-water sprinkler systems protect areas of a building or structure and equipment, whereas the foam-water spray system uses directional foam application to protect a specific hazard or piece of equipment within a building or structure. (Ch. 8 Review)

Discuss the events that led to the formation of the International Code Council in the 1990s.

The formation of the European Union and the adoption of the NAFTA treaty placed the three regional model code organizations in jeopardy of losing their competitive advantage. This was due to inconsistencies between the codes that forced manufacturing and construction businesses to deal with three different codes instead of one. (Ch. 2 Review)

Using the fire tetrahedron, describe four methods of fire extinguishment.

The four components of the fire tetrahedron are fuel, heat (energy), air (oxygen), and the chemical or self-sustaining chain reaction. By reducing, interrupting, or eliminating the fuel, less fuel is available to continue the combustion process. By cooling, the reduction in heat (energy) will not permit other available fuels to reach an ignition temperature that is to sustain the combustion process. By reducing the amount of available air (oxygen) below 16%, there is an insufficient amount of air to sustain the combustion process. By disrupting the uninhibited, chemical, or self-sustaining chain reaction, the reaction is unable to sustain the combustion process. (Ch. 1 Review)

Compare and contrast the four pressure differential methods used to control smoke.

The four methods are stairway, floating zone/floor-by-floor, hoistway, and refuge. All methods use the containment method to prevent the smoke and gases from either escaping an area or entering an area. (Ch. 12 Review)

(Ch. 13 Review)

List the stages of fire development and explain each.

The incipient stage occurs when the heat source, fuel, and oxygen come together to generate more heat than dissipated to promote the uninhibited chain reaction. The free burning stage occurs as fire consumes the surrounding air and materials necessary to generate the flammable gas that sustains the combustion process. The flashover stage occurs when all of the combustible contents in a compartment reach their ignition point and are consumed in flame. The smoldering or decay stage fire begins at the point at which the available fuel is exhausted or the oxygen level drops below 16%. (Ch. 1 Review)

What two changes in the commercial cooking industry prompted Underwriters Laboratories to update "Outline of Investigation, Subject 300" to the UL 300?

The introduction of high-efficiency appliances that heated cooking oils quicker, cooked hotter, and cooled at a slower rate and the introduction of vegetable oils that replaced animal fats (Ch. 9 Review)

What are the different life safety and fire protection systems that interface with smoke control systems?

The life safety and fire protection systems that interface with smoke control systems are fire sprinkler, fire alarm and detection, HVAC, elevators, fire doors, fire dampers, and backup power systems. (Ch. 12 Review)

Why is it important that fire mains are the correct size?

The line size must be large enough to meet the flow demands of the water-based fire protection system. (Ch. 5 Review)

Explain the differences between a local application system and a total flooding system.

The local application system protects exposed hazards that are sufficiently isolated from other exposures where the extinguishing agent discharges directly onto or near the hazard. The total flooding system protects an enclosed area where the agent fills the entire area to achieve extinguishment. (Ch. 9 Review)

Why is it so important to document the location of a duct detector?

The location of the detector must be documented and clearly identified because even if there is no fire or smoke, many duct detectors are very difficult or impossible to see from the floor level. (Ch. 3 Review)

What are the pressure ranges for low-, intermediate-, and high-pressure water mist systems?

The low-pressure systems are less than 175 psi, intermediate-pressure systems are between 175 psi and 500 psi, and high-pressure systems are in excess of 500 psi and in many installations, require pressures over 1000 psi. (Ch. 8 Review)

What are some of the problems associated with discharging wet and dry chemical agents? Are there alternative methods that would satisfy the minimum requirements of NFPA 17 and 17A for accepting new wet and dry chemical extinguishing systems? Should there be a requirement to perform a discharge test every few years?

The main problem is collecting and weighing the agent to prevent the agent from covering everything in sight and determining if the agent was evenly distributed. Many manufacturers do not recommend discharging the wet or dry agent to avoid creating problems with the piping and nozzles that could become clogged. Instead, the manufacturers recommend alternatives, including air or water or other noncorrosive agents plus the use of drying agents after any liquid-based test. The discharge test should be performed every few years to ensure the piping and nozzles are not clogged. (Ch. 9 Review)

What are the major components of a fire pump assembly besides the fire pump?

The major components of a fire pump assembly are the controller, the driver, and in some instances, the transfer switch. (Ch. 5 Review)

What information was stamped or applied to fire sprinkler heads manufactured before 2001?

The manufacturer's name or symbol, model number, type of head, K-factor, year of manufacture, listing or approvals, and temperature rating (Ch. 7 Review)

Are there specific building code requirements for the installation of specialized water-based fire protection systems? If so, what are they? If not, why not?

The model building codes state requirements to install automatic fire sprinkler systems or alternative fire suppression systems, but there is no language specifying a certain type of fire suppression system installation for the hazard. The system must protect the hazard by controlling or extinguishing the fire. Simply stated, the hazard determines the use of a particular type of system. Certain systems are appropriate for some hazards, conditions, and applications, but not other hazards, conditions, and applications. (Ch. 8 Review)

Why is there a need for visual notification appliances?

The need for visual appliances stems from conditions and situations in which people are not able to hear an audible alarm. This inability to hear an audible alarm is due to loud ambient noise levels, hearing loss, and deafness. (Ch. 3 Review)

Explain the differences between noninterlock, single-interlock, and double-interlock preaction systems.

The noninterlock arrangement requires two separate activation events but only if the first event is the fire detector activation; otherwise if a system sprinkler head activates first, the valve trips and water flows out of the activated sprinkler head. The single-interlock arrangement follows the requirement that a detector will release the water into the pipes but needs a sprinkler head to activate to flow water out of a sprinkler head. The double-interlock arrangement requires that both a detector and a sprinkler head activate before any water will flow into the piping and out of the sprinkler head. (Ch. 7 Review)

Why is the opposed air method of control rarely used?

The opposed air method of control requires very complex control and large air volumes in order to work. (Ch. 12 Review)

Why would it be inappropriate to install a water flow switch on a dry pipe sprinkler system?

The paddle of the switch arm could blow off and create a blockage somewhere in the pipe due to the velocity and force of the water rushing through the pipe of a dry, pre-action, or deluge system. (Ch. 3 Review)

Explain the differences between a pipe schedule-designed automatic fire sprinkler system and a hydraulically designed automatic fire sprinkler system.

The pipe schedule system relies on tables that are based on the type of hazard encountered and state how many fire sprinkler heads can be installed on a particular size of pipe. The hydraulically designed system relies on a mathematical method of determining flow and pressure at any point along the sprinkler system piping for determining pipe size throughout the system. (Ch. 7 Review)

Based on all of the maintenance and operational concerns associated with Class II standpipe systems, is there still a need to install Class II standpipe systems?

There are still communities where facilities, organizations, and operations utilize and maintain a Class II standpipe system as their primary manual firefighting equipment. However, in some urban areas where there are paid full-time fire departments and where equipment is readily available and maintained by department personnel, it is unlikely personnel would rely on equipment where the integrity is unknown. Therefore, installation of this type of system should be based on an evaluation of the communities' needs. For example, some urban jurisdictions do require installation of the hose valve and associated piping but do not require installation of the hose. (Ch. 6 Review)

Which of the following is a myth that requires further education in order to dispel the public's opinion of automatic fire sprinkler systems?

They cause more damage than they are worth. (pg 170)

List the code requirements for access-controlled egress.

· Secured doors must unlock upon activation of the automatic sprinkler, automatic fire detection, or fire alarm system (if installed in the building), and remain unlocked until fire protection system reset. · Secured doors must unlock by activation of a sensor located on the egress side of the door that detects occupants approaching the door. · Secured doors must unlock upon loss of power to the lock, locking mechanism, or sensor. · Secured doors must unlock by activation of a manual-unlocking device located no less than 40 inches and no more than 48 inches vertically above the floor and within 5 feet of the secured door. · Where there is a manual unlocking device, it must be accessible and clearly identified by a sign that reads "Push to exit." · When a manual unlocking device operates, it must immediately interrupt the power to the lock and remain unlocked for at least 30 seconds. · There must be emergency lighting at the door. (Ch. 13 Review)

What are the four major types of fire sprinkler systems and for what environment is each best suited for installation?

· Wet system—A system with water in the pipes at all time and best used where a minimum temperature of 40°F can be maintained at all times. Example: Office building · Dry system—A system with a gas (usually air) in the pipes in which a minimum temperature of 40°F cannot be maintained at all times. Example: Parking garage · Preaction system—A system that interfaces with fire detection equipment and requires a fire detector to activate and/or an automatic fire sprinkler head to operate to flow water. Example: Computer room · Deluge system—A system equipped with open fire sprinkler heads that simultaneously discharges water from all sprinkler heads. Example: Aircraft hangar (Ch. 7 Review)

Discuss the pros and cons of requiring smoke control and management systems. Which use and occupancy conditions would benefit from the installation of these systems, and which would not?

The pros are that the systems are designed to provide a tenable environment in a building during a fire emergency and, to a degree, keep hot gases and smoke confined. The cons are that these systems can be a challenge to design and require that the property owner or responsible party keep up with the required periodic inspection and testing. Without annual testing and receipt of documented reports, smoke control systems can rapidly fall into a state of disrepair or failed performance; this is particularly true in multi-tenant office buildings during the initial build-out of first-generation tenants. Problems may occur due to reprogramming of the fire alarm system for new tenant alarm devices, electrically disconnecting systems due to nuisance operation, damper motors failing to operate, intentionally disconnecting damper linkages, and fan motors tripped on thermal overload. Occupancies that would benefit include any place where there is an evacuation challenge, any location where it could take time to reach the exit discharge such as a high-rise or a subway station, large open space occupancies, and any location where people are not free to move about.
