Installation Manual
Auxiliary Intercom
An auxiliary intercom is a wired communication system that can be used in the
event of base station failure. The wiring diagram below shows where the
connections are made for a 3M™ Wired Intercom Systems Classic Series Model
D15. You can use a different brand of intercom system, but the wire color
coding will be different, so you will have to determine how to wire the systems
together by following the terminal labels.
