Ohio State Fire Alarm Practice Test 2 (2026)
1. What is the primary purpose of a fire alarm system?
A. Control building access
B. Detect fire conditions and notify occupants
C. Reduce utility costs
D. Monitor internet traffic
Correct Answer: B
Rationale: The primary purpose of a fire alarm system is to detect fire-related conditions and provide
timely notification to occupants so they can evacuate or take appropriate action.
2. Which NFPA standard governs fire alarm and signaling systems?
A. NFPA 13
B. NFPA 25
C. NFPA 72
D. NFPA 101
Correct Answer: C
Rationale: NFPA 72, the National Fire Alarm and Signaling Code, establishes requirements for the
design, installation, inspection, testing, and maintenance of fire alarm systems.
3. What device allows occupants to manually activate a fire alarm system?
A. Smoke detector
B. Heat detector
C. Pull station
D. Relay module
Correct Answer: C
Rationale: A manual pull station allows a person to initiate an alarm when a fire or emergency
condition is discovered.
4. Which type of smoke detector is generally more responsive to smoldering fires?
A. Ionization detector
B. Photoelectric detector
C. Heat detector
D. Flame detector
Correct Answer: B
Rationale: Photoelectric smoke detectors are more sensitive to larger smoke particles commonly
produced by smoldering fires.
,5. What does FACU stand for?
A. Fire Alarm Circuit Utility
B. Fire Alarm Control Unit
C. Fire Access Control Unit
D. Fire Alarm Communication Utility
Correct Answer: B
Rationale: FACU stands for Fire Alarm Control Unit, which serves as the central processing and
monitoring component of the fire alarm system.
6. Which signal indicates a fire emergency requiring immediate action?
A. Trouble signal
B. Supervisory signal
C. Alarm signal
D. Maintenance signal
Correct Answer: C
Rationale: An alarm signal indicates the detection of fire or a fire-related emergency condition
requiring immediate response.
7. Which color is commonly used to indicate a trouble condition on a fire alarm panel?
A. Green
B. Blue
C. Yellow/Amber
D. White
Correct Answer: C
Rationale: Yellow or amber indicators are commonly used to identify trouble conditions affecting
system operation.
8. Which circuit class provides a return path to the control panel?
A. Class B
B. Class C
C. Class A
D. Class E
Correct Answer: C
Rationale: Class A circuits return to the control unit, allowing operation to continue despite a single
open fault.
, 9. What is a supervisory signal?
A. Signal indicating fire
B. Signal indicating normal operation
C. Signal indicating an off-normal condition in a monitored system
D. Signal indicating battery charging
Correct Answer: C
Rationale: Supervisory signals indicate abnormal conditions affecting fire protection systems, such as
a closed sprinkler control valve.
10. What is the most common secondary power source for a fire alarm system?
A. Solar panels
B. Generator only
C. Rechargeable batteries
D. Capacitors
Correct Answer: C
Rationale: Rechargeable batteries provide backup power when primary AC power is interrupted.
11. What is the purpose of an end-of-line resistor?
A. Increase circuit voltage
B. Monitor circuit integrity
C. Improve speaker output
D. Ground the system
Correct Answer: B
Rationale: End-of-line resistors allow the fire alarm panel to supervise circuits and detect opens or
faults.
12. Which detector activates when a preset temperature is reached?
A. Smoke detector
B. Beam detector
C. Fixed-temperature heat detector
D. Aspirating detector
Correct Answer: C
Rationale: Fixed-temperature heat detectors operate when the sensing element reaches a specified
temperature threshold.
13. Which code primarily governs fire alarm wiring methods?
