The system allows the simultaneous full-duplex communication with multiples speaker units. By activating the intercom system through the dedicated firefighters' key, the speaker unit establishes an immediate handsfree communication between the machine room, the elevator car and the floors.
The system is made up by the Master Powercomm for the connection of the floor and cabin speaker units, and by the Floor Terminal and the Intercom speaker unit.
It is possible to connect up to 10 floor terminals over the dedicated BUS and 2 speaker units in the cabin. The terminals are waterproof IP-X3 with excellent speech quality and can be associated to pre-existing Esse-ti autodiallers.
