According to NFPA 70, what is the maximum unsupported length of 1/2-inch
flexible metallic conduit where flexibility is required after installation?
a) 6 feet
b) 3 feet
c) 4 1/2 feet
d) 5 feet
Correct Answer: c) 4 1/2 feet
Explanation:
The NEC (NFPA 70) limits the unsupported length of flexible metallic conduit to 4
1/2 feet when flexibility is necessary. This ensures that the conduit remains secure
and does not sag or become damaged, which could compromise the wiring inside.
What is the maximum bend (in degrees) permitted in a conduit run between
outlet boxes?
a) 180 degrees
b) 270 degrees
c) 360 degrees
d) 90 degrees
Correct Answer: c) 360 degrees
Explanation:
The NEC limits conduit bends between pull points (such as outlet boxes) to a total

of 360 degrees. This restriction ensures that conductors can be pulled through the
conduit without excessive difficulty or damage.
If the primary power is disconnected and the fire alarm system goes into an alarm
condition, what is the minimum acceptable time for secondary power to operate
the voice evacuation systems?
a) 5 minutes
b) 10 minutes
c) 15 minutes
d) 30 minutes
Correct Answer: c) 15 minutes
Explanation:
NFPA 72 requires that secondary power supplies support voice evacuation systems
for at least 15 minutes in full alarm condition. This ensures sufficient time for
occupant notification and safe evacuation during emergencies.
A riser room temperature switch should activate when the temperature falls
below which level?
a) 50°F
b) 45°F
c) 32°F
d) 40°F
Correct Answer: d) 40°F
Explanation:
Temperature switches in riser rooms are designed to activate when temperatures
drop below 40°F to prevent freezing of sprinkler system components. Freezing can
cause pipe damage and system failure, so early warning is critical.

According to NFPA 72, what is the maximum sound pressure level permitted in a
space with notification appliances?
a) 90 dBA
b) 100 dBA
c) 110 dBA
d) 120 dBA
Correct Answer: c) 110 dBA
Explanation:
NFPA 72 sets the maximum allowable sound level at 110 dBA to prevent hearing
damage while still ensuring that alarm signals are clearly audible during
emergencies.
What is the minimum interval for testing a single-station smoke detector in
multifamily units?
a) Monthly
b) Every 6 months
c) Annually
d) Every 2 years
Correct Answer: c) Annually
Explanation:
Single-station smoke detectors in multifamily dwellings must be tested at least
annually to ensure proper functionality and occupant safety.
Where should a technician install a detector in relation to a beam that is less than
12 inches deep and less than 8 feet on center?
a) Above the beam
b) At the ceiling center

c) At the bottom of the beam
d) Between beams only
Correct Answer: c) At the bottom of the beam
Explanation:
Shallow beams can affect smoke movement, so detectors should be placed at the
bottom of the beam to ensure proper smoke detection and response time.
An existing fire alarm cable in a drop ceiling will be spliced. Which one of the
following splice locations will comply with NFPA 70?
a) Inside conduit
b) Above ceiling tiles
c) Inside a junction box without cover
d) Secured inside a listed box or enclosure
Correct Answer: d) Secured inside a listed box or enclosure
Explanation:
The NEC requires all splices to be made within listed, accessible enclosures to
protect connections and allow for inspection and maintenance.
Which function shall be tested for each newly installed smoke detector?
a) Sensitivity level
b) Smoke entry
c) Alarm silence
d) Power consumption
Correct Answer: b) Smoke entry
Explanation:
Smoke entry testing confirms that smoke can physically enter the sensing chamber
and activate the detector, ensuring real-world functionality.
