ADDING DOOR SWITCH EXTENSION CABLE
When the Door Switch is installed far from the VM Controller, an extension will be provided with two wires,
BLACK and RED.
To connect the extension to a “NO” switch, using a Wire Connector join the T310 Black wire with the
extension’s Black wire and the T310 Brown wire with the extension’s Red wire, now the Black and Red wires
will be available. Cut the “NO” wire and join the Black one to the Door Switch and the Red one to the VMC.
