1. What is the primary purpose of a fire alarm system?
A. To extinguish a fire automatically
B. To detect fire conditions and provide notification
C. To ventilate smoke from a building
D. To provide emergency electrical power
Correct Answer: B. To detect fire conditions and provide notification
Explanation: A fire alarm system is primarily intended to detect conditions associated with fire
and alert occupants and responsible personnel. Depending on the system, detection may occur
through smoke detectors, heat detectors, initiating devices, or other equipment. Notification
appliances then communicate the alarm condition. Fire alarm systems do not normally extinguish
fires themselves.
2. Which NFPA standard is the principal standard governing the installation of fire alarm
and signaling systems?
A. NFPA 10
B. NFPA 13
C. NFPA 72
D. NFPA 101
Correct Answer: C. NFPA 72
Explanation: NFPA 72, the National Fire Alarm and Signaling Code, provides requirements for
fire alarm and signaling systems, including initiation, notification, inspection, testing,
maintenance, and documentation. NFPA 13 primarily addresses sprinkler-system installation,
while NFPA 101 addresses life safety. Inspectors commonly use NFPA 72 together with
applicable building, fire, and electrical requirements.
3. What is an initiating device?
A. A device that receives alarm signals and displays them
B. A device that starts a signal indicating a fire or supervisory condition
, C. A device that provides standby power
D. A device used only to silence notification appliances
Correct Answer: B. A device that starts a signal indicating a fire or supervisory condition
Explanation: Initiating devices detect or initiate conditions that are transmitted to the fire alarm
control unit. Examples include manual fire alarm boxes, smoke detectors, heat detectors,
waterflow switches, and supervisory switches. The control unit processes these signals and
determines the appropriate system response.
4. What is the function of a fire alarm control unit (FACU)?
A. To supply water to sprinklers
B. To process signals and control fire alarm system functions
C. To replace emergency lighting
D. To provide building heating
Correct Answer: B. To process signals and control fire alarm system functions
Explanation: The FACU is the central processing component of many fire alarm systems. It
receives signals from initiating devices, evaluates those signals, activates appropriate notification
appliances, and communicates supervisory, trouble, or alarm conditions. It may also control
auxiliary functions such as elevator recall or HVAC shutdown when properly interfaced.
5. Which condition normally indicates that a fire alarm system has detected a fire or fire-
related emergency?
A. Alarm
B. Trouble
C. Supervisory
D. Normal
Correct Answer: A. Alarm
Explanation: An alarm condition indicates that the system has received a signal requiring
emergency response. A trouble condition generally indicates a fault affecting system integrity,
while a supervisory condition indicates an abnormal condition involving a monitored fire
protection feature. Proper inspection requires distinguishing these conditions.
6. What does a supervisory signal generally indicate?
A. A confirmed building fire
B. A condition affecting a monitored fire protection system
C. Loss of all electrical power
D. A discharged fire extinguisher only
Correct Answer: B. A condition affecting a monitored fire protection system
,Explanation: Supervisory signals commonly originate from devices monitoring fire protection
equipment. Examples include sprinkler control valves being moved from their normal position or
low air pressure in certain sprinkler systems. Supervisory signals require attention but are
different from alarm signals.
7. What does a trouble signal indicate?
A. A fault or abnormal condition affecting the fire alarm system
B. A sprinkler has discharged
C. A fire has been verified
D. An evacuation has been completed
Correct Answer: A. A fault or abnormal condition affecting the fire alarm system
Explanation: Trouble signals indicate conditions such as open circuits, ground faults, battery
problems, loss of power, or equipment failures. A trouble signal should not simply be ignored or
silenced permanently. The underlying cause should be investigated and corrected.
8. Which component normally provides the primary power source for a fire alarm system?
A. Portable generator
B. Building electrical service
C. Smoke detector battery
D. Portable battery pack
Correct Answer: B. Building electrical service
Explanation: Fire alarm systems are normally supplied by the building's approved primary
power source. Secondary power is provided so the system can continue operating when primary
power is unavailable. The inspector should verify that power supplies, connections, and
indications operate correctly.
9. Why is secondary power required for many fire alarm systems?
A. To make the system wireless
B. To maintain operation when primary power fails
C. To increase detector sensitivity
D. To eliminate testing requirements
Correct Answer: B. To maintain operation when primary power fails
Explanation: A fire can interrupt normal building power, so the fire alarm system must be
capable of continuing operation using an approved secondary power source. Batteries are
commonly used. Inspection includes verifying the condition, connections, charging, and
performance of the secondary power supply.
10. Which device is manually operated to initiate a fire alarm signal?
A. Heat detector
B. Manual fire alarm box
, C. Waterflow switch
D. Duct detector
Correct Answer: B. Manual fire alarm box
Explanation: A manual fire alarm box allows a person to manually initiate an alarm when fire or
smoke is observed. It is commonly located along means of egress or other required locations.
Inspectors verify accessibility, physical condition, identification, and operation.
11. What is another common name for a manual fire alarm box?
A. Pull station
B. Horn relay
C. Notification module
D. Control relay
Correct Answer: A. Pull station
Explanation: "Pull station" is a common industry term for a manual fire alarm box. The device
is operated manually to initiate an alarm signal. During inspection, the device should be tested
according to the applicable procedures while ensuring the alarm condition is properly restored
afterward.
12. Which detector responds primarily to visible or invisible products of combustion?
A. Smoke detector
B. Pressure switch
C. Tamper switch
D. Flow switch
Correct Answer: A. Smoke detector
Explanation: Smoke detectors are designed to respond to smoke particles or combustion
products. Different technologies include ionization and photoelectric sensing, although modern
systems may use more advanced multi-criteria technologies. Detector selection and placement
must be appropriate for the environment.
13. What is the basic operating principle of a heat detector?
A. It detects changes associated with temperature
B. It measures carbon dioxide concentration only
C. It detects water pressure
D. It detects electrical resistance in notification appliances
Correct Answer: A. It detects changes associated with temperature
Explanation: Heat detectors respond when temperature reaches a predetermined level or
changes at a specified rate, depending on the detector type. Fixed-temperature and rate-of-rise
