1.
In a large campus networked fire alarm system, the primary
purpose of redundant network pathways is to:
A. Increase signal speed
B. Reduce wiring cost
C. Ensure system survivability during pathway failure
D. Simplify programming
Answer: C
Redundant pathways maintain communication even if one
pathway fails, which is required for survivability in mission-
critical systems.
2.
,According to NFPA 72, a Class X pathway differs from Class A
because:
A. It allows only one direction of signal flow
B. It provides isolation between short circuits
C. It requires wireless technology
D. It eliminates supervision
Answer: B
Class X pathways provide isolation so a single short does not
disable the entire loop.
3.
When designing a voice evacuation system, speaker audibility
must typically achieve:
A. 5 dB above ambient
B. 10 dB above ambient
C. 15 dB above average ambient
D. 20 dB above peak ambient
Answer: C
NFPA 72 requires voice messages to be audible at least 15
dB above average ambient sound level.
4.
Emergency control functions associated with smoke control
systems must be:
,A. Manual only
B. Fully supervised
C. Tested once per year only
D. Installed on non-fire circuits
Answer: B
Smoke control interfaces are critical life-safety functions
and must be supervised.
5.
When integrating fire alarm and mass notification systems,
priority must be given to:
A. Weather alerts
B. Fire alarm signals
C. Security announcements
D. Paging messages
Answer: B
Fire alarm signals always take priority over mass
notification messages.
6.
The survivability level required for pathways controlling
smoke control equipment is typically:
A. Level 0
B. Level 1
C. Level 2
D. Level 3
, Answer: C
Smoke control systems typically require Level 2 survivability.
7.
A risk analysis for emergency communication systems is
primarily used to determine:
A. Wire size
B. Battery capacity
C. System performance objectives
D. Manufacturer selection
Answer: C
Risk analysis defines system performance needs based on
hazards.
8.
Secondary power supply capacity for a large emergency voice
system must be calculated based on:
A. Maximum speaker wattage only
B. Standby plus alarm duration
C. Cable length
D. Amplifier type
Answer: B
Battery sizing includes standby duration plus full alarm
operation time.
