NOTE: It is not necessary to remove the remaining four screws - see sections 2.3 “FIRElink-400 Standard
Detector - Interior View” on page 8, 2.4 “FIRElink-400CM Command Module Detector – Interior
View” on page 9 and 2.5 “FIRElink-CM Stand Alone Command Module – Interior View” on page

Lift the display away from the main board. If the display needs to be completely removed, unplug the
display ribbon connectors from the detector or Command Module main board, taking note of the position
of the connectors which are as follows:
 For the Standard Detector (FIRElink-400), a single ribbon cable connected to the detector’s ‘Front
Panel’ display connector (see section 2.3 “FIRElink-400 Standard Detector - Interior View” on page
8).
 For the Command Module detector (FIRElink-400CM), a twin ribbon cable, one ribbon connected
to the detector’s ‘Front Panel’ display connector and marked ‘DISPLAY DET’, and one connected
to the Command Module board’s ‘Commander Display’ connector and marked ‘DISPLAY COM’
(see sections 2.4 “FIRElink-400CM Command Module Detector – Interior View” on page 9 and 2.5
“FIRElink-CM Stand Alone Command Module – Interior View” on page 10).
 For the stand-alone Command Module, a twin ribbon cable, one ribbon connected to the ‘Detector
Display’ connector and marked ‘COMMAND DET’, and one connected to the ‘Commander Display’
connector and marked ’COMMAND COM’ (see section 2.5 “FIRElink-CM Stand Alone Command
Module – Interior View” on page 10).
When completely removing the display it is recommended that the ribbon connectors
be removed from the main detector or Command Module board rather than from the
display board. When removing these connectors, ensure that suitable antistatic
precautions are taken, for example use of antistatic wrist straps, to prevent possible
static damage to the unit’s electronics. Refitting of the display is the reverse of the
above procedure
NOTE: Ensure that the connectors are refitted as described above.
To refit the front cover, hook the recessed lip at the top of the front cover behind the two retaining guard
rails at the top of the chassis like so:
