Multiple Keypads In A Zone - AMX Distributed Audio Controllers Delta Series Operation And Reference Manual

Multiple Keypads in a Zone

Certain situations such as large rooms or rooms with more than one common entrance may require more
than one keypad control to conveniently manage the zone. This configuration allows for 2 Matrix
keypads to be placed on the control circuit. Make sure that the second (AUX) keypad has the wire loop
cut so that it's addressed to the Delta Controller as an auxiliary keypad, rather than a "MAIN" keypad
(FIG. 9).

Main Keypad wiring
The main keypad wiring uses all four conductors and connects to speakers as normal. The
secondary keypad "taps off" of the D and G terminals of the main keypad input for a
secondary control point.
The secondary keypad must have the loop cut to configure it as the secondary (AUX) keypad.
