OHIO FIRE ALARM 2025 UPDATED EXAM WITH MOST TESTED
QUESTIONS AND ANSWERS | GRADED A+ | ASSURED SUCCESS
WITH DETAILED RATIONALES
1. Where Public Mode audible appliances are installed, they shall be ______ above the average
ambient sound level.
A) 5 dB
B) 15 dB
C) 25 dB
D) 30 dB
Rationale: NFPA 72 requires audible appliances in Public Mode to be 15 dB above ambient sound
levels to ensure audibility.
2. Where audible appliances are installed in mechanical equipment rooms, the average ambient
sound level is:
A) 60 dB
B) 75 dB
C) 85 dB
D) 100 dB
Rationale: Mechanical rooms often have high noise levels, so NFPA 72 sets the ambient sound level
at 85 dB for proper alarm audibility.
3. An average ambient sound level greater than ______ shall require the use of a visible notification
appliance.
A) 90 dB
B) 95 dB
C) 105 dB
D) 110 dB
Rationale: Environments exceeding 105 dB require visual alarms (strobes) because audible alarms may
not be effective.
4. All fire detection devices shall be listed or approved for the purpose for which they are intended.
,ESTUDYR
A) True
B) False
Rationale: NFPA 72 mandates that all fire detection devices must be listed and approved for their
intended use.
5. A detector should not be recessed in any way unless it has been tested for such mounting.
A) True
B) False
Rationale: Recessed mounting can affect detector performance, so they must be tested and
approved for such installation.
6. How far from the doorway shall a Manual Fire Alarm Station be mounted?
A) 3 ft
B) 5 ft
C) 7 ft
D) 10 ft
Rationale: NFPA 72 requires manual pull stations to be installed within 5 ft of exit doorways for easy
access.
7. Vane-type flow switches have no longer than _____ to initiate an alarm.
A) 30 sec
B) 60 sec
C) 90 sec
D) 120 sec
Rationale: NFPA 72 limits the delay to 90 seconds to ensure timely fire alarm activation.
8. Smoke detectors must be tested every:
A) 6 months
B) 1 year
C) 2 years
D) 5 years
, ESTUDYR
Rationale: NFPA 72 mandates annual testing of smoke detectors to ensure proper operation.
9. Sensitivity in smoke detectors and single & multiple-station smoke alarms in other than 1 & 2
family dwellings shall be checked within _____ year(s) after installation.
A) 1 year
B) 2 years
C) 3 years
D) 5 years
Rationale: NFPA 72 requires sensitivity testing within 1 year of installation to ensure proper detection.
10. A spot-type heat detector located on a wall shall not be more than _____ inches from the ceiling.
A) 6"
B) 12"
C) 18"
D) 24"
Rationale: Heat detectors must be within 12" of the ceiling to detect rising heat effectively.
11. With a peak ceiling, heat and smoke detectors shall be located within _____ of the peak,
measured horizontally.
A) 24"
B) 36"
C) 48"
D) 60"
Rationale: NFPA 72 requires detectors to be within 36" of the peak for optimal coverage.
12. Smoke detectors shall not be located near:
A) Walls
B) Corners
C) Air supply diffusers
D) Ceilings
Rationale: Air diffusers can disrupt smoke flow, leading to delayed or missed alarms.
