1. What is the primary purpose of a fire alarm system?
A. Automatically extinguish every fire in a building
B. Detect fire conditions and provide notification to occupants and
emergency responders
C. Control all electrical equipment in a building
D. Replace the need for fire suppression systems
,Rationale: A fire alarm system detects indications of fire, such as
smoke or heat, and initiates appropriate notification and control
functions. It helps occupants evacuate and alerts emergency
personnel. Although it may interface with suppression systems, it does
not replace fire suppression equipment or guarantee that a fire will be
extinguished.
2. Which component receives signals from initiating devices and
determines the appropriate system response?
A. Notification appliance
B. Manual pull station
C. Fire alarm control unit (FACU)
D. End-of-line resistor
Rationale: The fire alarm control unit receives and processes signals
from initiating devices and other system components. Based on its
programming and configuration, it activates notification appliances,
transmits signals, and operates connected control functions. End-of-
line resistors supervise circuits rather than process system-wide alarm
information.
3. Which device is specifically designed to allow a person to manually
initiate a fire alarm?
,A. Heat detector
B. Smoke detector
C. Manual fire alarm box
D. Duct detector
Rationale: A manual fire alarm box, commonly called a pull station,
allows a person to initiate an alarm without waiting for an automatic
detector to respond. It is typically installed along designated means of
egress and must be accessible and identifiable.
4. What is the principal function of a smoke detector in a fire alarm
system?
A. Measure the structural strength of a building
B. Detect airborne particles associated with combustion
C. Measure water pressure in sprinkler piping
D. Detect carbon monoxide exclusively
Rationale: Smoke detectors respond to airborne combustion particles
using technologies such as photoelectric or ionization sensing. They
provide early warning of many fire conditions. Smoke detectors are
not interchangeable with carbon monoxide detectors, which are
designed to detect a different gas.
, 5. Which condition generally causes a fire alarm control unit to
indicate a trouble signal?
A. A properly operating detector senses smoke
B. A manual pull station is activated
C. An open circuit occurs on a supervised initiating circuit
D. A notification appliance operates normally
Rationale: An open circuit in a supervised circuit can interrupt the
electrical path used for monitoring field devices. The control unit
generally identifies this abnormal condition as trouble. An actual fire
input normally produces an alarm signal, while normal appliance
operation does not ordinarily indicate a trouble condition.
6. What does a supervisory signal generally indicate?
A. A confirmed fire in an occupied room
B. An abnormal condition involving a monitored fire protection
system or its equipment
C. A complete loss of all building electrical power
D. A routine detector cleaning cycle
Rationale: Supervisory signals commonly indicate abnormal
conditions involving systems such as sprinkler control valves, fire
