Recovery from a flat battery
Should the battery pack become discharged, the unit will no longer function -
this could be in the locked or unlocked state. The application of an external PP3
9V battery will allow the circuitry to operate as normal.
This allows the door to be opened with a valid user card giving access to the lock
allowing the battery pack to be replaced.

When the battery voltage falls below 4V, the user will see a delay between the card being read and access being
granted. This delay provides a warning that the battery pack should be replaced.
The warning delay starts at 5 seconds, increasing up to 25 seconds as the battery discharges with use.
Low battery warning
Alarm sounder
The alarm is activated when the door fails to re-lock itself. The alarm will sound for 60 seconds during which time
the unit will try to lock the door once every 0 seconds. After 60 seconds the unit will then shut down. When
the unit is woken up, it will immediately try to lock the door. If it fails, the alarm cycle will start again. Failure to
relock will substantially reduce battery life.
