10 Maintenance
Local standards and specification requirements must be adhered to. A typical maintenance procedure
could entail the following steps:
Check detector, wiring and
pipework for damage
T
Check original design is still
valid, e.g. changes due to
building upgrades
T
Check detector for
contamination and clean if
necessary
T
Check maintenance logs for
issues and rectify as appropriate
T
Isolate detector from the fire
panel if required
T
Smoke test to check detector
operation and Fire relay
connection
T
Check transport times against
original records: significant
increases or decreases in
transport times may imply
damaged pipes or sampling
holes that need clearing
T
Simulate a Fault to check the
Fault relay and connection
T
Complete and file maintenance
records
T
Reconnect detector to fire panel
if required
NOTE: It is prudent to disconnect or isolate the detector from the fire panel during maintenance to prevent
unintentional alarm activations.
NOTE: The detector should be powered down during internal cleaning (use an air duster can or dry air
gun).
