1. What is the primary purpose of a fire alarm control panel in a fire
alarm system?
A. To extinguish fires automatically
B. To monitor and control the fire alarm system
C. To notify the fire department only
D. To provide emergency lighting
The fire alarm control panel serves as the central hub, monitoring all
devices and initiating alarms when necessary.
2. Which type of fire detector is most effective at detecting
smoldering fires?
A. Ionization smoke detector
B. Photoelectric smoke detector
C. Heat detector
D. Flame detector
Photoelectric detectors respond quickly to larger smoke particles typical
of smoldering fires.
, 3. What is the standard voltage for initiating circuits in a fire alarm
system?
A. 120 V AC
B. 240 V AC
C. 24 V DC
D. 12 V DC
Most fire alarm initiating devices operate on 24 V DC for safety and
compatibility.
4. Which device is designed to provide a visible warning during a
fire?
A. Pull station
B. Heat detector
C. Strobe light
D. Smoke detector
Strobe lights alert occupants visually, especially those who are hearing
impaired.
5. What is the minimum power supply requirement for a fire alarm
system?
A. 50% of total load
B. Primary and secondary (backup) power
C. Only battery power
D. Only AC power
Fire alarm systems require both primary and secondary power to ensure
operation during power failure.
6. Which NFPA standard specifically covers the installation of fire
alarm systems?
, A. NFPA 101
B. NFPA 72
C. NFPA 72
D. NFPA 13
NFPA 72 provides comprehensive guidelines for fire alarm system
installation, testing, and maintenance.
7. What is the primary function of an initiating device circuit (IDC)?
A. To power notification appliances
B. To detect fire or smoke conditions
C. To supply backup power
D. To connect the system to the fire department
IDCs are designed to sense smoke, heat, or manual activation and
report it to the control panel.
8. Which type of fire alarm notification appliance is designed to
produce sound?
A. Strobe
B. Horn or speaker
C. Pull station
D. Smoke detector
Horns or speakers produce audible alerts to notify occupants of an
emergency.
9. In a supervised fire alarm system, what does “supervised” mean?
A. The system is monitored by a security guard
B. The system automatically extinguishes fires
C. The control panel monitors circuits for faults
D. The system is tested daily
, A supervised system can detect circuit failures, open or short circuits,
ensuring reliability.
10. What is the typical spacing requirement for smoke detectors
in a commercial building?
A. 10 ft
B. 30 ft
C. 50 ft
D. 60 ft
NFPA 72 guidelines specify detector spacing to ensure effective
coverage.
11. Which type of heat detector responds when a set
temperature is reached?
A. Rate-of-rise detector
B. Fixed-temperature detector
C. Ionization detector
D. Photoelectric detector
Fixed-temperature detectors activate when the temperature reaches a
predetermined threshold.
12. What is the purpose of a water flow switch in a sprinkler
system connected to a fire alarm system?
A. To shut off sprinklers
B. To alert the fire department only
C. To detect water movement and trigger an alarm
D. To test sprinklers
Water flow switches detect the movement of water when a sprinkler
operates and signal the alarm system.
