Ohio Fire Alarm Practice Test 3
1. What is the primary purpose of a fire alarm system?
A. Reduce insurance premiums
B. Detect fire conditions and notify occupants
C. Replace sprinkler systems
D. Eliminate all fire risks
Answer: B
Rationale: The main function of a fire alarm system is to detect fire-related conditions and provide
timely notification so occupants can evacuate safely and emergency responders can be alerted.
2. Which device is designed to detect visible combustion particles?
A. Heat detector
B. Ionization detector
C. Smoke detector
D. Pull station
Answer: C
Rationale: Smoke detectors sense smoke particles produced by a fire. They provide early warning
before heat levels become dangerous.
3. What type of detector generally responds faster to flaming fires?
A. Photoelectric detector
B. Heat detector
C. Ionization detector
D. Carbon monoxide detector
Answer: C
Rationale: Ionization detectors are typically more responsive to fast-flaming fires that produce
smaller combustion particles.
4. Manual fire alarm boxes are commonly known as:
A. Horns
B. Pull stations
C. Annunciators
D. Relays
Answer: B
Rationale: A pull station allows occupants to manually activate the fire alarm system when a fire is
discovered.
,5. What does NAC stand for?
A. Network Alarm Circuit
B. Notification Appliance Circuit
C. National Alarm Code
D. Notification Access Control
Answer: B
Rationale: A Notification Appliance Circuit supplies power and signaling to horns, strobes, speakers,
and other notification devices.
6. Which device provides a visual fire alarm signal?
A. Horn
B. Bell
C. Strobe
D. Detector
Answer: C
Rationale: Strobes provide flashing visual signals to assist occupants, including those who may have
hearing impairments.
7. What is the primary function of a fire alarm control unit (FACU)?
A. Supply water to sprinklers
B. Monitor inputs and control system outputs
C. Ventilate smoke
D. Operate elevators only
Answer: B
Rationale: The FACU serves as the central processing unit of the fire alarm system, receiving signals
and initiating responses.
8. A supervisory signal indicates:
A. Fire emergency
B. Trouble condition only
C. Off-normal condition of a fire protection system
D. Power failure
Answer: C
Rationale: Supervisory signals monitor conditions such as closed sprinkler valves or abnormal system
status that could affect protection.
, 9. A trouble signal indicates:
A. Confirmed fire
B. System impairment or fault
C. Occupant evacuation completed
D. Sprinkler activation
Answer: B
Rationale: Trouble signals identify issues such as wiring faults, battery problems, or device failures
requiring maintenance.
10. What is the purpose of standby batteries?
A. Improve signal volume
B. Provide backup power during outages
C. Reduce wiring costs
D. Increase detector sensitivity
Answer: B
Rationale: Standby batteries keep the fire alarm system operational when normal electrical power is
unavailable.
11. Which detector type responds to a fixed temperature threshold?
A. Rate-of-rise detector
B. Fixed-temperature heat detector
C. Smoke detector
D. Flame detector
Answer: B
Rationale: A fixed-temperature heat detector activates when a predetermined temperature is
reached.
12. What is an annunciator panel used for?
A. Power distribution
B. Fire suppression
C. Displaying system status information
D. Battery charging
Answer: C
Rationale: Annunciators provide a remote display showing alarm, supervisory, and trouble
conditions.
13. Which NFPA standard primarily governs fire alarm systems?
