1. Which NFPA standard provides the primary installation
requirements for fire alarm systems?
A. NFPA 3
B. NFPA 25
C. NFPA 101
D. NFPA 72
NFPA 72 contains installation, testing, and maintenance requirements
for fire alarm systems.
2. A Class A signaling line circuit (SLC) must be capable of:
A. Maintaining operation with a single ground fault only
B. Maintaining operation with a single open in the circuit
C. Operating without a return path
D. Serving NAC and SLC simultaneously
Class A circuits provide redundant return paths, keeping the circuit
operational if one path opens.
3. Which device type typically requires an end-of-line resistor?
,A. Addressable pull station
B. Conventional smoke detector circuit
C. Addressable relay
D. Intelligent heat detector
Conventional initiating circuits require EOL devices for supervision.
4. For audibility requirements in sleeping areas, NFPA 72 mandates a
minimum of:
A. 70 dBA
B. 75 dBA
C. 85 dBA
D. 60 dBA
Sleeping areas require at least 75 dBA measured at the pillow.
5. A fire alarm control unit located in an unoccupied mechanical room
must:
A. Not require any protection
B. Be accessible to authorized personnel
C. Be installed outdoors
D. Be mounted at least 15 ft above the floor
FACP accessibility and environmental protection are required.
6. What type of circuit must restore its function automatically after a
fault is cleared?
A. Class D
B. Class E
C. Class A
D. Class X
Class A circuits automatically return to full operation after fault
removal.
, 7. A fire alarm system with elevator recall features must follow
requirements found in:
A. NFPA 1
B. NFPA 13
C. NFPA 72 and ASME A17.1
D. NEC Article 500
Elevator recall uses both fire alarm and elevator safety standards.
8. Which device is required in an elevator machine room when
sprinklers are installed?
A. Combination smoke/heat detector
B. Pull station
C. Class A NAC
D. Heat detector
Elevator machine rooms require heat detection if sprinklers are present.
9. A fire alarm secondary power supply must support the system for:
A. 12 hours standby and 10 minutes alarm
B. 24 hours standby and 5 minutes alarm
C. 6 hours standby and 15 minutes alarm
D. 72 hours standby and 30 minutes alarm
Typical requirements for most systems are 24 hours plus 5 minutes.
10. A releasing control panel for clean agent systems must comply
with:
A. NEC Article 700
B. NFPA 13
C. NFPA 2001
D. NFPA 20
NFPA 2001 covers clean agent extinguishing systems.
