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
Recovery from a at 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
With the product xed securely to the door:
1) Hold the door unlocked by presenting the fail open release card.
2) Check that the handles are running smoothly. This is best done by depressing the handle all the
way to the bottom and then releasing it as slowly as possible. If the handle is left behind at any
point, it is likely that the product has not been installed squarely enough. Check the handle on
both sides of the door.
3) If your nger is able to leave the handle, remove the unit from the door (or slacken the four
mounting screws) and see if the problem goes away. If it does, the installation onto the door is at
fault and the drilling of the mounting holes should be checked for alignment.
4) Return the door to normal operation by presenting the fail open release card again.
This test conrms the correct and free operation of the mechanical lock and also ensures that the
electronic circuits will shut down correctly preserving battery life.
Commissioning checks
The door open time should be kept to a minimum to preserve battery life.
