Using the Emergency Card on the lock to be opened, a green light will turn on and the lock unlocked until you release the emergency open mode. In order to release the emergency open mode activate the deadbolt. If the emergency open stays on use the DTU tablet or Legacy – in the Lock Control menu select release EM and send the information to the lock. Since the lock is on, a DTU card is not needed.

Note: the Emergency Card can open all locks in the building and override the deadbolt.

In this case consider the following two options :

a) The mortise is not properly plugged to the board. Please remove the back of the lock to make sure the mortise is properly plugged – we recommend unplugging and plugging it back to the board. You will hear a click on the mortise – if so it means the mortise is OK. Now again try the key to confirm it is operational.

If the mortise does not make the click sound, try the key to confirm it is still not working. If so, we suggest trying with a different mortise.

b) The antenna reader is not properly plugged to the board. Please make sure the antenna reader is plugged to the board – we recommend unplugging and plugging it back to the board. Now try the key, fob or wristband to confirm if the antenna reader is operational or needs to be changed.

Note : Confirm all wires are in good condition.
