, 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.

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 **

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?
