If it needs to connect the lock to the door intercommunication system, the door video intercommunication system or the external button of remote opening:
Connect the contacts C1, C5 of socket of external connections to terminals of operating relay of the door intercommunication system, the door video intercommunication system or the external button of remote opening. In that case resistance of connecting wires should not exceed 100 Ohm.
At that connection the lock operates as usual, and when you press the KEY button on the door intercommunication system the lock will unfasten (lock opening will be submitted by the light and/or sound signal on the both lock keyhandles) and will be opened unless the door will be opened. At door closing the lock will fasten.
If you set up auto-fastening (function 34), the lock will be in open position after pressing the KEY button for a time set up by the function.
