Battery Replacement

A coin-style battery (Cr1220 or Br1220) powers the real time clock

during a power loss.

To replace the battery:

1. Unplug the control module from wall outlet.

2. Hinge the control module forward to access the connection

panel.

3. Remove the zone run connections. They should already be

labeled, if not, label before removing (for example: Zone 1 Run

2).

4. Remove the six screws that hold the panel.

5. Taking care not to disturb the other connections, lift the panel

to expose the coin battery in its housing at the front left of the

module.

6. Use a ball-point pen to dislodge the existing battery.

7. Insert a new battery with the positive (+) side facing upward.

8. Replace the connection panel, securing all six screws. Reconnect

the zone run cables.
