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).
