Keypad 2 Wire Control Only Configuration
In some retrofit configurations it is not feasible or possible to re-route the speaker cable
through the keypad. In cases such as this, it is possible to run a separate cable pair
(CAT- 3 / CAT- 5 / Twisted Pair) cable from the MRC- 8e to the keypad device for control
purposes.This diagram shows the connections of the control signal path to the keypad,and
the speaker connections to the MRC- 8e.
