Emergency and Standby Power Systems

True or False? Fire extinguishers must be in a glass case mounted on the wall.

Portable fire extinguishers

True or False? An alarm can be activated both manually and automatically.

True.

True or False? Manual fire alarms must typically be placed within 5 feet from the latch side of an exit door.

True.

Most alarms must be audible and what?

Visible

True or False? The decision to use an automatic sprinkler system, fire detection system, or smoke detector system is mostly based.

False, the decision is mostly based on occupancy type and/or size of the building.

True or False? The codes do not allow the connection of fire and smoke alarm systems to the building's security system.

False, this is allowed and often used in new technology systems. However, some jurisdictions may have restrictions.

Which of the following statements about detection systems is true? a. Smoke detectors should be located next to the intersection of a wall or ceiling. b. If heat detectors are used, smoke detectors are not necessary for accurate detection. c. Smoke detectors are especially effective in detecting smoldering fires. d. All of the above are correct.

c. Smoke detectors are especially effective in detecting smoldering fires. (Detection systems must be 4 inches from the intersection of a wall and ceiling, if too close it will be inactive. Heat and smoke detectors are used together.)

Which of the following is not typically allowed by the codes because a sprinkler system is provided? a. A reclassified occupancy type b. An increased travel distance c. A lower finish classification d. A lower fire resistance rating of a structural element

a. A reclassified occupancy type

What type of systems direct occupants out of the building during an emergency by verbal command? a. Emergency voice alarm communication system b. Accessible warning system c. Visual/audible alarm system d. a and c

a. Emergency voice alarm communication system

Which type of sprinkler system would typically be used where the system would be exposed to freezing temperatures? a. Wet pipe system b. Dry pipe system c. Deluge system d. Fast-response system

b. Dry pipe system (pipes aren't filled with water until heat is detected as to not freeze the pipes. Pipes are filled with pressurized air or nitrogen.)

Which of the following statements about fire-related codes is not correct? a. They control building materials such as ducts, wiring, and pipes. b. Elements and devices required by fire-related codes do not have to meet accessibility requirements of the ADA and ABA. c. They include provisions for fire protection and smoke protection. d. All of the above.

b. Elements and devices required by fire-related codes do not have to meet accessibility requirements of the ADA or ABA. (Accessibility requirements cover alarm and accessible warning systems, reaching distances, and protrusions into path of travel.)

Which of the following is not considered an alarm system? a. Accessible warning system b. Manual fire alarm c. Voice communication system d. Mass notification system

b. Manual fire alarm is considered a detection system, not alarm system, since it requires an occupant to alarm it.

When specifying a visual alarm, which of the following are regulated by the codes and the ADA standards? a. Height b. Color and intensity c. Flash rate and duration d. All of the above

d. All of the above

Which class of standpipe is designed for use by building occupants? a. Class I b. Class II c. Class III d. b and c

d. b and c (Class II is designed for occupant use and Class III is designed for occupant and fire department use. Class I is only designed for fire department use.)

NFPA 170

fire safety and emergency symbols

Which of the following is not a type of sprinkler head? a. Residential b. Pendant c. Large-drop d. Fast-response

b. Pendant (This is a sprinkler orientation, such as upright, sidewall, recessed, and concealed. Sprinkler heads: standard, fast-response, residential, quick-response, extended coverage, open, and large-drop.)

Which of the following is not typically used by the codes to determine if a standpipe is required in a building? a. The number of stories in a building b. The number of stairwells in a building c. A sprinkler system is located in the building d. The type of occupancy located in the building

b. The number of stairwells in a building (although used in stairwells, the number of stairs doesn't determine if a standpipe is required.)

Which of the following is not considered a detection system? a. Smoke or heat detectors b. Manual fire alarms c. Firestops d. b and c

c. Firestops. A firestop is a through-penetration protective and part of a prevention system.

Which of the following statements about an EVACS is not correct? a. It provides direction to the occupants during an emergency. b. Its speaker locations are based on paging zones created within the building. c. It is required in most occupancy classifications. d. It is similar to a public address system.

c. It is required in most occupancy classifications. (EVACS, Emergency Voice/Alarm Communication Systems, are most often required in high rises and hazardous buildings.

When required in a Class A space, the codes typically require that no occupant can be more than how many feet from a fire extinguisher?

75'

True or False? Only multiple-station smoke detectors are required by the codes to be tied into the building's power source, but single-section smoke detectors are not.

False, both must be tied into the building's power source.

True or False? When a fire occurs, detection system only detects presence of smoke.

False, some detection systems can detect smoke, other gases, heat and change in temperature, or multiple symptoms of fire.

Which of the following sprinkler head orientations are available recessed and surface mounted? a. Pendant and sidewall b. Upright and pendant c. Concealed and sidewall d. Upright and conceiled

a. Pendant and sidewall

Which of the following specialty types of rooms or areas is the most likely to use a non-water-based fire extinguisher system? a. Restaurant kitchen b. Atrium c. Trash chute d. Boiler room

a. Restaurant kitchen

Which of the following would affect the need for a sprinkler system? a. Building size b. Occupancy type c. Specific room use d. All of the above

d. All of the above

How much clearance is typically required below the head or deflector of a sprinkler?
