Recovery from a flat battery
Should the battery pack become discharged, the latch will no longer function.
This could be in the locked or unlocked state.
Holding a PP3 9V battery up to the contacts on the bottom of the unit will allow
the circuitry to operate normally.
A valid user card can then be used to open the door to access the batteries.
+ve -ve
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 2 seconds, increasing up to 10 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 10 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.
