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.
What type shall general purpose wire be? What substitutions are permitted? -
CORRECT ANSWER-Power Limited Fire Alarm (FPL) CMP,FPLP,CMR,FPLR,CMG,
and CM can be substituted. (All types)
What is the maximum voltage permitted through multi-conductor NPLFA cables? -
CORRECT ANSWER-150 volts
