Installation
Connecting A Power Failure Telephone
The system provides a tip and ring pair connected to
line one that is to be used as an emergency power
failure circuit. This power failure pair is located on
Mod jack 1 for all common equipment models. This
jack is the right-most jack when facing the right side of
the cabinet. The power failure pair is only active
during an AC power failure. An industry standard
single-line telephone, such as a Comdial2500-xx can
be connected
to
the power failure pair and used to
provide communications capability should the AC
power to the system be interrupted.
