RECOMMENDABLE FOR GRADE A+
1. A fire alarm system is primarily designed to:
A. Suppress fire automatically
B. Detect fire conditions and alert occupants
C. Provide structural support during fire
D. Replace sprinkler systems
✔ Correct Answer: B (Detect fire conditions and alert occupants)
Explanation: Fire alarm systems are intended to detect fire indicators such
as smoke or heat and notify occupants for evacuation and response.
2. Which document provides the fundamental requirements for fire alarm
systems installation in the United States?
A. NEC Article 250
B. NFPA 72
C. OSHA 1910
D. IBC Chapter 1
✔ Correct Answer: B (NFPA 72)
, Explanation: NFPA 72, the National Fire Alarm and Signaling Code, governs
installation, testing, and maintenance of fire alarm systems.
3. A manual pull station is classified as what type of device?
A. Initiating device
B. Notification appliance
C. Control unit
D. Power supply
✔ Correct Answer: A (Initiating device)
Explanation: Manual pull stations initiate an alarm signal when activated
by a person.
4. Smoke detectors typically respond to:
A. Temperature rise only
B. Visible flame
C. Particles in the air
D. Pressure changes
✔ Correct Answer: C (Particles in the air)
Explanation: Smoke detectors sense combustion particles suspended in
the air.
5. Heat detectors are best suited for areas where:
A. Smoke is always present
B. Rapid evacuation is required
C. Dust or fumes may cause false alarms
D. Fire risk is low
✔ Correct Answer: C (Dust or fumes may cause false alarms)
Explanation: Heat detectors are used where smoke detectors would
produce nuisance alarms due to environmental conditions.
6. A notification appliance circuit (NAC) is used to:
A. Power initiating devices
B. Connect detectors
C. Operate horns and strobes
, D. Monitor wiring faults
✔ Correct Answer: C (Operate horns and strobes)
Explanation: NACs provide power and signaling to notification appliances
such as horns and strobes.
7. The primary function of a fire alarm control panel (FACP) is to:
A. Extinguish fires
B. Monitor and control system inputs and outputs
C. Supply water
D. Vent smoke
✔ Correct Answer: B (Monitor and control system inputs and outputs)
Explanation: The FACP processes signals from devices and controls
notification appliances.
8. In a conventional system, devices are grouped into:
A. Loops
B. Zones
C. Nodes
D. Circuits only
✔ Correct Answer: B (Zones)
Explanation: Conventional systems organize devices into zones to indicate
general alarm locations.
9. Addressable systems differ from conventional systems because they:
A. Use more wiring
B. Identify exact device locations
C. Cannot detect smoke
D. Require no maintenance
✔ Correct Answer: B (Identify exact device locations)
Explanation: Addressable systems assign unique addresses to each device
for precise identification.
10.A supervisory signal indicates:
A. Fire condition
