Audio intercom kit including buttonhole and headset.
The external dashboard has 1 button for surface wall mounting, vandal resistant.
The handset is designed to operate at 220V but has a button to open the switch.
The connection is two-wire between the handset and the conversational. When controlling an elbow-type locking device, two more wires are needed next to the handset. The system can work with 2 or 3 handsets tied in parallel, and when the bell button is pressed, they all ring simultaneously.
