Cabinet Key Lock
The key lock should not be operated unless the screw locks are tight, i.e. Unlock the case before
undoing the screw lock and only lock the case after tightening the screw locks.
Inspect the main door seal and Manual Panel gasket, ensuring they are intact and in the correct
position. Replace as necessary ensuring that the surface is clean before fitting.
Check the Manual Panel for any damage and replace if necessary. Check that all functions operate
correctly. Press the lamp test keypad and check that all LEDs are operational.
Check the termination panel(s) and master switch panel within the controller and ensure that
there are no loose fixings, or damage to these panels. Tighten any loose fixings and carry out any
repairs that are necessary.
Check the logic rack(s) and other assemblies within the controller are securely fixed. Retighten
loose fixings as necessary.
Ensure that no fault indications are showing.
Fuse Testing
The following tests will result in the signals extinguishing.
Test the 300mA RCD (if fitted) by pressing the test button. The breaker should operate
immediately.
Check that all fuses are secure in their holders. It is strongly recommended that the controller
supply is isolated before any fuses are checked.
Check for damage all wiring, cables and cable forms, particularly any of the more vulnerable small
gauge, single insulation wires and cables, such as ribbon cables. Repair or replace if necessary.
If fitted, the RTC battery backup cell on the CPU Card must be replaced if it has passed the replace
by date on the label below the coin cell holder. The date label supplied with the replacement kit
should be fitted over the existing label. Having done this, the controller records should be updated
accordingly.
