physical damage such as chafing, bending, twisting, or
breaking has occurred. Replace attaching parts when
found to be defective.
Bends will not be less than two
inches in radius.
Replace cable detector only when physical
damage such as chafing, bending, twisting, or breaking
has occurred. Make all bends and routing with fingers
only. Replace attaching parts when found to be defective
thermocouple detectors when cracked, corroded, or
damaged. Replace attaching parts when found to be
connected to identified plug terminal
replacement in the same way.
Testing of Fire Detection System Test fire
detection system using the following procedures
Test system for proper operation by turning
on power supply and placing FIRE DET TEST switch in
test position Red warning light should flash on within 10
seconds. Turn switch and power off
Test required after repair or replacement of
units in fire detector system or when system is Inoperative
Replace lamp in warning light, when warning
light does not flash on.
Polarity, ground, resistance, and continuity tests
are required for systems with thermocouple
detect or units.
Resistance and continuity tests are required for
systems with sensing elements or cable

Fire Extinguishing Systems. The fire extinguisher
system Is the one-shot type consisting of one or more
monobromotrifluoromethane (CB and CF3Br), discharging
tubing, overboard discharge tube, discharge indicator,
circuit breakers, and control panel switch. The container

Maintenance of Fire Extinguishing Systems.
Maintenance of fire extinguisher system consists of
Inspection and replacement of defective parts using the
Check for specific pressure on pressure
gauge as given In applicable aircraft maintenance manual
Inspect overboard discharge indicator for
evidence of system being discharged due to thermal
