FREQUENTLY TESTED QUESTIONS AND
ANSWERS IN DETAILS 100% VERIFIED
EXAM HIGHLY RECOMMENDABLE FOR
GRADE A+
1. A fire alarm control unit (FACU) is required to provide which primary
function in a protected premises system
A. HVAC control
B. Signal processing and system supervision
C. Lighting control
D. Elevator speed regulation
✔ Correct Answer: B. Signal processing and system supervision
Explanation: The FACU is the central component that receives, processes,
and supervises all fire alarm signals and system status conditions.
2. Which NFPA standard governs fire alarm system installation
A. NFPA 10
B. NFPA 13
C. NFPA 70
, D. NFPA 72
✔ Correct Answer: D. NFPA 72
Explanation: NFPA 72 is the National Fire Alarm and Signaling Code, which
outlines requirements for installation, performance, and maintenance.
3. A Class B initiating device circuit will result in what condition when a single
open occurs
A. System failure
B. Entire system shutdown
C. Loss of devices beyond the break
D. Alarm condition
✔ Correct Answer: C. Loss of devices beyond the break
Explanation: Class B circuits lose communication with devices past the
open but continue operating for devices before the break.
4. What type of detector is most suitable for detecting smoldering fires
A. Ionization detector
B. Photoelectric detector
C. Heat detector
D. Flame detector
✔ Correct Answer: B. Photoelectric detector
Explanation: Photoelectric detectors are more responsive to visible smoke
from smoldering fires.
5. A supervisory signal indicates
A. Fire condition
B. System normal operation
C. Off-normal condition of system equipment
D. Trouble condition
✔ Correct Answer: C. Off-normal condition of system equipment
Explanation: Supervisory signals indicate abnormal conditions such as valve
closures or pressure issues in suppression systems.
, 6. What is the primary purpose of end-of-line resistors
A. Increase voltage
B. Detect circuit integrity
C. Reduce current
D. Enhance sensitivity
✔ Correct Answer: B. Detect circuit integrity
Explanation: End-of-line resistors allow the system to monitor wiring
continuity and detect opens or shorts.
7. A notification appliance circuit (NAC) is used to
A. Detect fire
B. Power initiating devices
C. Activate horns and strobes
D. Monitor sprinkler valves
✔ Correct Answer: C. Activate horns and strobes
Explanation: NACs provide power and signaling to notification appliances to
alert occupants.
8. Which device senses a fixed temperature threshold
A. Rate-of-rise detector
B. Fixed temperature heat detector
C. Smoke detector
D. Beam detector
✔ Correct Answer: B. Fixed temperature heat detector
Explanation: Fixed temperature detectors activate when a preset
temperature is reached.
9. In addressable systems, each device has
A. Shared identity
B. No identification
C. Unique address
D. Analog signal only
✔ Correct Answer: C. Unique address
