1. Which of the following is the primary purpose of a fire alarm
system?
A. To suppress a fire automatically
B. To provide early warning of a fire **
C. To ventilate smoke from a building
D. To detect carbon monoxide
Rationale: The main purpose of a fire alarm system is to alert occupants
and emergency responders as early as possible so that life safety is
prioritized.
2. What type of fire detector is most responsive to flaming fires?
A. Ionization smoke detector **
B. Photoelectric smoke detector
C. Heat detector
D. Carbon monoxide detector
Rationale: Ionization detectors respond faster to small, fast-flaming fires
because they detect ionized particles produced by combustion.
3. A photoelectric smoke detector works best for detecting:
A. Smoldering fires **
B. Explosions
C. Rapidly spreading flames
D. Carbon monoxide
,Rationale: Photoelectric detectors are more sensitive to larger smoke
particles, common in slow, smoldering fires.
4. Which of the following is a component of a fire alarm control
panel?
A. Notification appliance circuits **
B. Fire extinguisher
C. Fire hose
D. Sprinkler head
Rationale: The control panel manages initiating devices and outputs,
including notification appliances like horns and strobes.
5. NAC in a fire alarm system stands for:
A. Network Access Control
B. Notification Appliance Circuit **
C. Neutral Alarm Conductor
D. Node Activation Channel
Rationale: NACs supply power and signals to notification devices such as
horns, bells, and strobes.
6. Which wiring method is typically required by code for fire alarm
circuits?
A. Twisted pair over CAT5
B. Nonmetallic sheathed cable
C. Listed fire alarm cable **
D. Coaxial cable
Rationale: Fire alarm cables must meet UL listing and fire-resistance
requirements to ensure signal integrity during a fire.
, 7. A common power supply requirement for a fire alarm control
panel is:
A. 120 VAC primary with 24 VDC secondary **
B. 240 VAC only
C. 12 VDC only
D. 48 VAC
Rationale: Standard fire alarm panels operate on 120 VAC with a 24 VDC
output for powering devices.
8. What is the minimum duration that a secondary (battery) power
supply must operate a fire alarm system in normal conditions?
A. 15 minutes
B. 30 minutes
C. 24 hours **
D. 7 days
Rationale: Batteries must maintain system operation for 24 hours in
standby, plus additional time for alarm conditions.
9. Which of the following devices directly initiates a fire alarm
signal?
A. Control panel
B. Smoke detector **
C. Notification appliance
D. Supervisory switch
Rationale: Initiating devices like smoke or heat detectors, and manual
pull stations, send signals to the control panel.
10. The NFPA standard most commonly referenced for fire alarm
systems installation is:
, A. NFPA 13
B. NFPA 72 **
C. NFPA 70
D. NFPA 101
Rationale: NFPA 72 is the National Fire Alarm and Signaling Code,
covering installation, testing, and maintenance.
11. A manual pull station must be installed:
A. In a mechanical room only
B. Near exits and at accessible locations **
C. Above 8 feet from the floor
D. Only in high-rise buildings
Rationale: Manual pull stations must be accessible to occupants and
located along exit paths for quick activation.
12. Which of the following is a supervisory signal in a fire alarm
system?
A. Smoke detector activation
B. Fire pump trouble **
C. Horn activation
D. Sprinkler water flow
Rationale: Supervisory signals indicate abnormal conditions in
equipment required for fire protection, such as a valve or pump issue.
13. What is the typical voltage of a notification appliance circuit
(NAC)?
A. 12 VDC
B. 24 VDC **
