What does "Locked" mean on ACO CDNP7ACC Intercom System?
If the ACO Intercom System displays the message "Locked", it indicates that calling the selected apartment is locked. This can be adjusted via program P3.
What to do if ACO CDNP7ACC won’t initiate the connection after call?
If, after a call and picking up the handset, the ACO Intercom System doesn’t initiate the connection and continues ringing, check the resistance of the uniphone line. The resistance between the farthest ends of the line must be less than 60??. Otherwise, solder the connections, check or replace the wiring, or align the uniphone line (increase the cable cross section). For testing, disconnect all receivers and connect one receiver on short wires near the door entry unit.
