TFM 12 FIRE ALARM ACTUAL PREP BANK
2026 EXPERT SOLUTIONS CONFIRMED
◉ What is used to protect transformers or other devices supplied from
power-supply conductors? Answer: An over-current device not rated
over 20 amperes for a PLFA system. For a NPLFA system, it is 7
amps if using 18 AWG wire, 10 amps if using 16 AWG wire, and for
14 AWG or larger, refer to article 315 in the NFPA 70.
◉ When located within 7 feet of the floor, how shall cables be
fastened? Answer: Cables shall be fastened in an approved manner at
intervals of not more than 18 inches.
◉ Single conductors shall not be smaller than ___ AWG? Answer: 18
◉ Conductors of 26 AWG shall only be permitted in which
circumstance? Answer: When used in a multi-conductor cable.
◉ How shall PFLA conductors NOT be installed? Answer: PFLA
conductors shall not be strapped, taped, or attached to the exterior of
any conduit or raceway.
◉ What is Plenum cable? Answer: Cable that can be installed in
ducts, plenums, or other spaces used for environmental air, and shall
also be listed as having adequate fire-resistant and low smoke-
producing characteristics.
, ◉ What is a Riser cable? Answer: Cable to be used in vertical wire
runs in shafts between floors. Not to be used where Plenum cable is
required.
It is capable of preventing fire from rising from floor to floor.
◉ What is general purpose cable? Answer: Cable for general purpose
fire alarm use. Not to be used where plenum cable or riser cable is
required.
It is resistant to the spread of fire.
◉ Why 'type' shall plenum cable be? What substitutions are allowed?
Answer: FPLP; CMP can be substituted.
◉ Why 'type' shall riser cable be? What substitutions are allowed?
Answer: FPLR; CMR, FPLP, and CMP can be substituted.
◉ What 'type' shall general purpose wire be? What substitutions are
permitted? Answer: FPL; CMG, CM, CMP, FPLP, CMR, FPLR, can
be substituted.
◉ What is the maximum voltage permitted through multi-conductor
NPFLA cables? Answer: 150 volts
