Contact Closure Support for 2 Devices (FEATURE 41 and FEATURE 42)

The IP500 v2 Control Unit has a Contact Closure control jack on the back panel. This is a 3.5 mm stereo jack that can drive two external adjunct relays.

This feature allows users at eligible extensions to control an external adjunct by entering feature codes at their system or standard telephone. The port can control a variety of devices, the most common being door strikes, night bells, lighting, or voice recording systems.
