2. Lift the PCB free of the PCB mounting slots.
To replace the PCB:

2. Ensure that any cabling is clear of the PCB support pillars.
3. Gently pull back the PCB mounting clips and place the PCB on top of the
PCB support pillars.
4. Release the PCB mounting clips ensuring that they spring back into place
and that the PCB is held firmly in place.

SW1 — Accord Tamper
Switch SW1 on the Accord control panel PCB is the control panel tamper. Removing the
enclosure lid releases the tamper switch; this causes a tamper alarm if the system is not in
programming mode.
Note: The installer must attach the Tamper switch pin and spring supplied with the
ancilleries pack in order for the tamper to operate.
