2015 Operations Manual

Battery Failure Override

The DoorBox has been designed so a standard PP3 (9 Volt) battery can be placed against the

contact points surrounding the Blue and Red light so the lock can be opened to replace the

batteries should they fail.

The procedure is as follows:

1. Place the contact points of the PP3 (9 Volt) battery against the contact points

surrounding the Blue and Red light.

2. The positive + PP3 (9 Volt) terminal against the Red light contact point and the negative

– PP3 terminal against the Blue light.

3. Enter the Master Code. The motor will withdraw the locking pin allowing the lock to be

opened.

4. Open the lid and from the interior of the DoorBox remove the rear-ﬁxing bolt and screw

that secures the lock to the DoorBox.

5. Peel the lock from the DoorBox and turn it over to reveal the battery compartment.

Simply replace the batteries and re-install the lock.
