Operation Diagram
Wiring diagrams
Use connection lines independent from other lift circuits.
Preliminary operations
Before connecting the CITCOC handset intercom device it is necessary to insert the resistor supplied (22 Ohm) as in the picture.
In pre-wired systems (handset intercom device CITCOC.P / CITCOC.P40) it is not necessary to carry out this intervention because it has already been done in DMG.
Intercom system with hands-free intercom device (CITCAB) in the elevator car
For connection with DMG pre-wired systems, please consult the relevant installation guide.
Intercom system with AMIGO emergency telephone
For connection with DMG pre-wired systems, please consult the relevant installation guide.
