Communication/Intercom Disconnects

Communication/Intercom Secondary Disconnects are designed to expand the number and type of circuits that can be disconnected. They are used for intercom wiring and can also be used to disconnect additional communication conductors connected to a dispenser.

SECONDARY DISCONNECTS

Secondary Communication/Intercom Disconnects expand the capability of the primary disconnect. They connect to and are controlled by any Primary Disconnect via the included 6’ and 25’ DB-9 cables. These Secondary Disconnects are used for communication circuits with 4 or 8 conductors per dispenser.


Emergency Stop

Secondary Disconnects connect to the primary disconnect allowing secondary circuit conductors to be disconnected when the emergency stop system is activated.

Intercom Disconnect

Handles any intercom configuration that uses 1 call button & 1 speaker, 2 call buttons, or 2 speakers per dispenser OR an intercom configuration that uses 2 call buttons & 2 speakers per dispenser.

Easy Installation

Individual disconnects for each circuit types allows the disconnect to be located where the conductors enter the building. This can eliminate costly additional wiring and downtime that maybe required to re-route conductors to a central location such as the electrical room, during a retrofit or site upgrade.
