1. What is the primary purpose of a fire alarm system?
a. To provide general building lighting
b. To control HVAC temperature
c. To detect fire conditions and provide notification
d. To monitor electrical consumption
Answer: c. To detect fire conditions and provide notification
Rationale: A fire alarm system is designed to detect conditions
associated with fire and alert occupants and appropriate responding
personnel. Detection, notification, monitoring, and related control
functions work together to support life safety.
2. Which device is primarily designed to detect visible smoke
particles?
,a. Heat detector
b. Smoke detector
c. Waterflow switch
d. Manual pull station
Answer: b. Smoke detector
Rationale: Smoke detectors sense smoke particles produced by
combustion. Depending on the detector type, they may use
photoelectric or other sensing technologies to identify smoke before
temperatures become high enough to activate many heat detectors.
3. What is the main function of a manual fire alarm box?
a. Automatically detect smoke
b. Allow occupants to manually initiate an alarm
c. Supply standby power
d. Regulate sprinkler pressure
Answer: b. Allow occupants to manually initiate an alarm
Rationale: A manual fire alarm box, commonly called a pull station,
allows a person who observes a fire or emergency condition to initiate
the fire alarm system manually.
4. Which component is considered the central processing unit of a
conventional fire alarm system?
,a. Notification appliance
b. Initiating device
c. Fire alarm control panel
d. End-of-line resistor
Answer: c. Fire alarm control panel
Rationale: The fire alarm control panel receives signals from initiating
devices, processes those signals, activates appropriate notification
appliances, supervises system circuits, and may communicate alarm or
supervisory conditions to a monitoring facility.
5. What does an end-of-line resistor primarily accomplish on a
supervised initiating circuit?
a. Increases available voltage
b. Allows the panel to supervise circuit integrity
c. Amplifies alarm signals
d. Converts AC power to DC power
Answer: b. Allows the panel to supervise circuit integrity
Rationale: An end-of-line resistor establishes the expected electrical
condition of a supervised circuit. If the circuit is opened or otherwise
changes beyond the expected range, the control panel can identify a
trouble condition.
, 6. Which condition generally indicates that a fire alarm system
requires attention but is not necessarily an active fire alarm?
a. Alarm
b. Trouble
c. Evacuation
d. Notification
Answer: b. Trouble
Rationale: A trouble condition indicates a fault or abnormal condition
affecting system supervision or operation. Examples include wiring
faults, power problems, or disabled equipment.
7. What is the purpose of standby batteries in a fire alarm system?
a. To provide decorative emergency lighting
b. To operate the system when normal primary power is unavailable
c. To increase detector sensitivity
d. To eliminate the need for circuit supervision
Answer: b. To operate the system when normal primary power is
unavailable
Rationale: Fire alarm systems require reliable power during
emergencies. Standby batteries provide secondary power when the
