1. What is the primary purpose of a fire alarm system?
A. To prevent fires from occurring
B. To alert occupants of a fire **
C. To extinguish fires automatically
D. To inspect electrical wiring
Rationale: The primary function of a fire alarm system is to alert
occupants to evacuate during a fire.
2. Which type of fire detector responds to heat rather than smoke?
A. Ionization smoke detector
B. Photoelectric smoke detector
C. Heat detector **
D. Carbon monoxide detector
, Rationale: Heat detectors activate when a certain temperature or
rate of rise is reached, unlike smoke detectors.
3. 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.
4. What is the minimum audible sound level required for a fire alarm in
sleeping areas?
A. 60 dB
B. 65 dB
C. 75 dB **
D. 85 dB
Rationale: NFPA 72 specifies a minimum of 75 dB at the pillow level
in sleeping areas to ensure occupants are awakened.
5. Which component of a fire alarm system receives signals from
detectors and initiates notification?
A. Initiating device
B. Control panel **
C. Notification appliance
D. Circuit breaker
, Rationale: The control panel monitors devices and activates alarms

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