Where multiple door-entry phones or monitor backplates have the same user code, connect the CFP button on one
only; all the devices will ring simultaneously.
20 m MAX - Use shielded cable for the connection and do not route the cables in the vicinity of heavy inductive loads
or power supply cables (230V/400V).
Programming
• Each door-entry phone in the system is identified by means of its own code. This code must be set using the Dip switch on
the phone card.
• The user code must be set according to the corresponding information provided in the programming table (see: “Dip
switch programming table”).
• Coding can take place at any time, even without a power supply.
