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 A firestop is a through-penetration protective and part of a prevention system. A manual fire alarm is part of the detection system because it is a device activated by an occupant upon detection of a fire

Which of the following statements about detection systems is correct? 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 necessarily for accurate detection. C. Smoke detectors are especially effective in detecting smoldering fires D. all of the above are correct

C Placing a smoke detector too close to the intersection may not provide accurate detection. Codes and standards require a smoke detector to be a minimum of4 inches from a wall/ceiling intersection so that air currents do not cause smoke and heat to bypass the unit. Heat and smoke detectors are often used together to require two indicators of fire for more accurate detection.

NFPA 12

Carbon Dioxide Extinguishing Systems

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

The decision to use an automatic sprinkler system, fire detection system, or smoke detection system is mostly based

FALSE Although budget may be a consideration, the choice of system will most often be dictated by the codes based on the occupancy type and / or the size of the building

Only multiple-station smoke detectors are required by the codes to be tied into the buildings' power source, but single-station smoke detectors are not

FALSE Both multiple-and single-station smoke detectors must be tied into the building's power source.

Fire extinguishers must be in a glass case mounted on the walls.

FALSE Fire extinguishers van be surface mounted using a bracket, or recessed within a wall using a cabinet. The cabinet can have either a vision panel or a solid door that is clearly marked

The codes do not allow the connection of fire and smoke alarm systems to the building's security system

FALSE New technology allows fire and smoke alarm systems to be tied to the other building controls such as the mechanical system or the security system, although some jurisdictions may restrict the extent of these connections

When a fire occurs, a detection system only detects the presence of smoke

FALSE Depending on the type of a detector, a detection system can detect smoke and other gases, heat and changes in temperature, or multiple symptoms of fire

fire safety and emergency symbols

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

75 feet

Which of the following is not considered an alarm system? A. Accesible warning system B. Manual fire alarm C. Voice communication system D. Mass notification system

B. A manual alarm system is considered a detection system because it is used by an occupant after he or she detects a fire

NFPA 110

Emergency and Standby Power Systems

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. Emergency voice/alarm communication systems are most often required in high-rise buildings, as well as hazardous building types such as factories and large storage facilities

What type of system directs 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 systems use an intercom to verbally direct the occupants out of a building. Visual/audible alarm systems use a variety of different sounds and light patterns to direct occupants, but no verbal direction. An accessible warning system encompasses devices that would be used in addition to typical visual, audio, and voice communication systems

Manual fire alarms must typically be placed within 5 feet from the latch side of an exit door

TRUE

An alarm can be activated both manually and automatically

TRUE An alarm system can be activated manually using a pull station, or automatically upon the operation of an automatic sprinkler system, fire detection system, or smoke detection system.
