- What is the primary purpose of a fire alarm system?
- To prevent fires from occurring
- To alert occupants of a fire **
- To extinguish fires automatically
- To inspect electrical wiring
Rationale: The primary function of a fire alarm system is to alert
occupants to evacuate during a fire.
- Which type of fire detector responds to heat rather than smoke?
- Ionization smoke detector
- Photoelectric smoke detector
- Heat detector **
- Carbon monoxide detector
Rationale: Heat detectors activate when a certain temperature or
rate of rise is reached, unlike smoke detectors.
- What NFPA standard governs the installation of fire alarm systems?
A. NFPA 13
B. NFPA 72 **
C. NFPA 101
D. NFPA 70
Rationale: NFPA 72 is the National Fire Alarm and Signaling Code,
which outlines installation and maintenance standards.
- What is the minimum audible sound level required for a fire alarm in
- 60 dB
- 65 dB
- 75 dB **
- 85 dB
sleeping areas?
Rationale: NFPA 72 specifies a minimum of 75 dB at the pillow level
in sleeping areas to ensure occupants are awakened.
- Which component of a fire alarm system receives signals from
- Initiating device
- Control panel **
- Notification appliance

- To notify the fire department only
- To test the fire alarm system
Rationale: Manual pull stations provide a means for occupants to
trigger the alarm if they discover a fire.
- Which type of fire detector is most responsive to smoldering fires?
- Ionization detector
- Photoelectric detector **
- Heat detector
- Flame detector
Rationale: Photoelectric detectors are better at detecting slow,
smoldering fires because they sense visible smoke particles.
- What is the purpose of a NAC (Notification Appliance Circuit)?
- To provide power to the control panel
- To activate notification devices like horns and strobes **
- To communicate with the fire department
- To monitor smoke detectors
Rationale: NACs deliver power from the control panel to audible and
visual notification appliances.
- Which type of fire alarm system is designed for a single building and is
- Addressable system
- Conventional system **
- Central station system
- Remote station system
self-contained?
Rationale: Conventional systems divide the building into zones, each
wired to a control panel.
- What is the advantage of an addressable fire alarm system?
- Lower installation cost
- Each device has a unique address for precise location identification
- No maintenance required
- Uses less wiring than a conventional system
**
Rationale: Addressable systems allow precise identification of which
detector or device has activated.
- How often should fire alarm systems be tested according to
NFPA 72?
- Monthly for all devices
- Weekly for control panels only
- Annually for all devices **
- Every 5 years
