Lift Cabin Audio Unit – Compact 2.344CANCEL Input Connection (Door Contact, Optional)This input helps cancel a rescue request if the lift is fully functional. When the ALARMbutton is pressed, the system waits for a pre-programmed period of time, which is alittle longer than the maximum lift running time. If the lift is functional, it arrives inthe required station within this timeout and opens the door. In that case, the rescuerequest is cancelled. If the door fails to open, the request is accepted.Make sure before installation that the “door open” signal is available in the lift cabin.Requirements In double-door lifts, the signal has to be active only if both the doors opensuccessfully and let the people out. The door position signal has to work even in the case of power outage.Contact controlRequirements None of the CANCEL terminals may be connected electrically with any otherelectrical circuit and a voltage source other than the contact.Instructions1.
