WITH ANSWERS | LATEST UPDATE .
What does PLFA stand for? - Correct Answer -Power Limited Fire Alarm
What does NPLFA stand for? - Correct Answer -Non Power Limited Fire Alarm
What material must NPLFA circuit conductors be made from - Correct Answer -Only solid or stranded
copper is permitted
What is a single station detector? - Correct Answer -Battery powered smoke detectors that do not
communicate off premises.
What is a multiple station detector? - Correct 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.
How frequently must household single and multiple single station detectors be inspected and
tested? - Correct Answer -In accordance with the manufactures recommendations, at least monthly.
How frequently must household single and multiple station detectors be inspected and tested? -
Correct Answer -At least 3 years, by a qualified service technician.
How frequently must heat detectors be tested? - Correct Answer -Two or more annually, different
detectors must be tested each year, and within 5 years all detectors must have been tested.
What does "restorable" mean? - Correct Answer -The detector can be "restored" or "reused" after it
has initiated.
What does "non-restorable" mean? - Correct Answer -The detector cannot be 're-used" after it has
initiated an alarm. (Think of a heat detector, which self destructs upon initiating.)

, What size conductors are permitted? - Correct Answer -Size 18 AWG and 16 AWG are permitted,
provided they do not exceed certain rated ampacities
What is used to protect transformers or other devices supplied from power-supply conductors? -
Correct Answer -An overcurrent device not rated over 20 Amperes
When located within 7ft of the floor, how shall cables be fastened? - Correct Answer -Cables shall be
fastened in an approved manner at intervals of not more than 18 inches.
Single conductors shall not be smaller that ___ AWG? - Correct Answer -18
Conductors of 26AWG shall only be permitted in which circumstances? - Correct Answer -Where
spliced with a connector listed as suitable for 26 to 24 AWG.
How should PLFA conductors NOT be installed? - Correct Answer -PLFA conductors shall not be
strapped, taped or attached to the exterior of any conduit or raceway.
What is Plenum cable? What are its characteristics? - Correct Answer -Cable that can be installed in
ducts, plenums or other spaces used for environment air. It has adequate fire resistance and low
smoke-producing characteristics.
What is riser cable? What are its characteristics? - Correct Answer -Cable to be used in vertical wire
runs in shafts or between floors. Not to be used where Plenum cable is required. It is capable of
preventing fire from rising form floor-to-floor.
What is Genral Purpose Cable? What are its characteristics? - Correct Answer -Cable for general
purpose fire alarm use. Not to be used where Plenum or Riser cable is required. It is resistant to the
spread of fire.
What type shall plenum cable be? What substitutions are allowed? - Correct Answer -Power Limited
Fire Alarm Plenum (FPLP) CMP can be substituted.
What type shall riser wire be? What substitutions are permitted? - Correct Answer -Power Limited
Fire Alarm Riser (FPLR) CMP,FPLP,CMR can be substituted.
