CERTIFICATION EXAM OFFERED BY NICET |
Q&A WITH RATIONALES
1. What is the primary function of a fire alarm
system?
A) To extinguish a fire
B) To notify occupants and emergency responders
of a fire condition
C) To pressurize stairwells
D) To shut down HVAC systems
Correct answer: B
Rationale: The primary function of a fire alarm
system is to detect a fire, notify occupants, and alert
emergency responders. Extinguishment is the role
of suppression systems.
2. Which organization publishes NFPA 72, the
National Fire Alarm and Signaling Code?
A) International Code Council (ICC)
B) National Fire Protection Association (NFPA)
C) Underwriters Laboratories (UL)
,D) American National Standards Institute (ANSI)
Correct answer: B
Rationale: NFPA 72 is published by the National Fire
Protection Association (NFPA), which develops
codes and standards for fire and life safety.
3. A fire alarm control unit (FACP) is listed under
which UL standard?
A) UL 268
B) UL 864
C) UL 1971
D) UL 609
Correct answer: B
Rationale: UL 864 is the Standard for Control Units
and Accessories for Fire Alarm Systems. UL 268
covers smoke detectors, UL 1971 covers visual
notification appliances, and UL 609 covers heat
detectors.
4. According to NFPA 72, what is the maximum
allowable delay from the operation of an initiating
,device to the automatic activation of a fire safety
function?
A) 5 seconds
B) 10 seconds
C) 15 seconds
D) 20 seconds
Correct answer: B
Rationale: NFPA 72 Section 23.8.1.2 specifies that
the delay from the operation of an initiating device to
the automatic activation of a fire safety function
(e.g., elevator recall) shall not exceed 10 seconds.
5. A system that serves contiguous or
non‑contiguous properties under one ownership is
considered what type of system?
A) Central station system
B) Proprietary system
C) Remote station system
D) Auxiliary system
Correct answer: B
, Rationale: A proprietary system is defined as a fire
alarm system that serves contiguous or
non‑contiguous properties under one ownership.
6. According to NFPA 72, secondary power for
remote supervising station systems shall be capable
of normal operation for how many hours and then
operate the system in alarm for how many minutes?
A) 12 hours / 5 minutes
B) 24 hours / 5 minutes
C) 24 hours / 15 minutes
D) 48 hours / 15 minutes
Correct answer: B
Rationale: NFPA 72 requires secondary power for
remote supervising station systems to be capable of
24 hours of normal operation followed by 5 minutes
of alarm operation.
7. What is the minimum conductor size for a
non‑power‑limited fire alarm circuit (NPLFA)
according to NFPA 70?
A) 14 AWG
