ModuLaser Modular Aspirating Smoke Detector Installation Manual 81
Cleaning the detector
The outside of the detector should be cleaned with a damp cloth when
necessary.
Caution: Do not use solvents to clean the detector. Use of solvents may damage
the detector.
Replacing the dust filter cartridge
Replace the dust filter as described below, when required. Used dust filter
cartridges are not intended for reuse and should be discarded.
The detector will indicate a Filter fault when the filter value (on the detector status
screen, see “Detector status” on page 42) reaches 20%.
The detector should be powered on when replacing the dust filter to ensure that
the filter status is reset.
WARNING: Health hazard: The dust in the dust filter will expose maintenance
personnel to health hazards, due to the environment of the area being protected.
It is recommended that suitable masks and protective clothing be worn when
changing filters. Maintenance work must be performed in compliance with
national and/or regional requirements and other applicable standards.
