8 Maintenance
FIRElink-25 is a very low maintenance detection system. If required, external cleaning of the unit should
be performed using a damp (not wet) cloth. Do not use solvents as these may mar the front panel label.
The only part that may require field replacement during servicing is the dust separator assembly. The
dust separator condition can be checked using the Dust Separator test in the Miscellaneous tab of the
remote software ‘Detector settings’ screen (see section 2.8.3) which gives a percentage reading of dust
separator efficiency. When this level drops to 80% the detector will signal a fault and the dust separator
will need replacing. To replace the filter, simply remove the front cover and pull the filter out from the
main unit. Slide the replacement filter in so that the ‘Direction of flow’ arrow printed on the carton
duplicates that on the ‘Direction of flow’ label beside the filter slot.
As dust contained in the dust separators may expose maintenance personnel to a ‘Nuisance Dust‘ hazard
as defined by the ‘Control of Substances Hazardous to Health‘ (COSHH), it is strongly recommended that
suitable masks and protective clothing be worn when changing filters.
Used separators are not
intended for re-use and should be disposed of.
8.1 Diagnostics
The remote control software includes a diagnostic function which carries out a number of checks to verify
the correct functioning of the detector. A good time to run these tests is as a part of planned
maintenance. To call up diagnostic mode, select the menu options

Cancel button.
