Metreau Keypads

Two-Wire Configurations – Keypad for Control Only

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

Matrix Controller to the keypad for control purposes.

When using CAT3/CAT5 over long runs, it is recommended to "double-up" the control wires (only 2

conductors are required, and there are 4-8 wires available).

FIG. 28 shows the connections of the control signal path to the keypad, and the speaker connections to the

Matrix Controller.
