TFM 12 FIRE ALARM TECHNICAL
FINAL TEST 2026 QUESTIONS WITH
CORRECT ANSWERS GRADED A+
◍ Primary purpose of a fire alarm system.
Answer: To detect and warn about fire, allowing for evacuation and fire
suppression.
◍ Power Limited Fire Alarm (
P. L.
F. A.).
Answer: A fire alarm system where the power delivered to the system is
limited to prevent risk of fire.
◍ What does NPLFA stand for?.
Answer: Non Power Limited Fire Alarm
◍ What material must NPLFA circuit conductors be made from.
Answer: Only solid or stranded copper is permitted
◍ Non-Power Limited Fire Alarm (
N. P.
L. F.
A. ).
Answer: A fire alarm system where the power delivered is not limited,
potentially posing a fire risk.
◍ What is a single station detector?.
Answer: Battery powered smoke detectors that do not communicate off
premises.
◍ What is a multiple station detector?.
, Answer: Mains powered smoke detectors with battery backup that are linked
together, so that if one unit initiates, alarms in all detectors will sound. They
do not communicate off premises.
◍ Difference between
P. L.
F. A. and
N. P.
L. F.
A. systems.
Answer: P.L.F.A. limits power to prevent fire risk, while N.P.L.F.A. does
not limit power, potentially posing a fire risk.
◍ Type of conductors for
N. P.
L. F.
A. circuits.
Answer: Conductors with higher fire resistance to prevent fire hazards.
◍ How frequently must household single and multiple single station detectors
be inspected and tested?.
Answer: In accordance with the manufactures recommendations, at least
monthly.
◍ A.
W. G..
Answer: American Wire Gauge, important in fire alarm systems for
specifying wire sizes.
◍ Purpose of over-current protection in fire alarm systems.
Answer: To prevent excessive current that can lead to overheating and fire
hazards.
◍ How frequently must household single and multiple station detectors be
inspected and tested?.
Answer: At least 3 years, by a qualified service technician.
, ◍ How cables should be fastened within 7 feet of the floor.
Answer: Cables should be fastened to structural components to prevent
damage.
◍ Condition for conductors of 28
A. W.
G. .
Answer: Permitted when used for power-limited fire alarm circuits.
◍ How frequently must heat detectors be tested?.
Answer: Two or more annually, different detectors must be tested each year,
and within 5 years all detectors must have been tested.
◍ Installation of
P. F.
L. A. conductors.
Answer: Should not be installed in a raceway with conductors of electric
light, power, or Class 1 circuits.
◍ What does "restorable" mean?.
Answer: The detector can be "restored" or "reused" after it has initiated.
◍ Plenum cable.
Answer: Cable with fire-resistant insulation used in plenum spaces for
improved fire safety.
◍ Riser cable.
Answer: Cable designed for vertical runs between floors in a building.
◍ General Purpose cable.
Answer: Standard cable not specifically designed for plenum or riser spaces.
◍ What does "non-restorable" mean?.
Answer: The detector cannot be 're-used" after it has initiated an alarm.
(Think of a heat detector, which self destructs upon initiating.)
◍ Monitoring requirements for fire hood systems and kitchens.
Answer: Specific requirements for monitoring systems in areas prone to
