Detector
Head dirty
It is recommended that the detector is replaced for new. Please Note: Where temporary work
involving the generation of dust, smoke, paint spray, and other aerosols is to be carried out in an
area protected by smoke detectors, the removable dust covers supplied with the device should be
fitted to prevent contamination or false alarms. The devices should also be temporarily disabled
at the Control Panel. Care must also be taken to ensure that the dust covers are removed and the
devices re-enabled once the environment is clear.
Warning: No attempt should be made to open the case for cleaning inside the head.
