Recovery from a at battery
Should the battery pack become discharged, the unit will no longer function and the door
mechanism will then fail to operate.
There is provision on the underside of the lock to apply an external PP9 battery that will provide
voltage to allow the circuitry to operate as normal.
NOTE: This does not release the lock directly but allows it to operate in its normal secure
operation. Once the door is open, access to the lock will then allow the internal battery pack to
be replaced.
When the battery has discharged to within the 3.5-4V minimum operating threshold. The user
will experience a delay between the card being read and access being granted. This delay is by-
design and acts as a warning that the battery pack is low and should be replaced.
As an example; the delay will at rst be 5 seconds.
The user will present their card as normal then the LED will show green for the 5 second delay,
after which access is granted normally.
The delay will increase in increments up to 25 seconds as the battery continues to discharge.
