INSTALLATION INSTRUCTIONS
MRCKPSP
Multi-Room Controller, Keypad Splitter
DESCRIPTION
The MRCKPSP provides the installer with the ability to wire two keypads to one zone without daisy-
chaining the keypads in the zone. This makes pre-wiring instructions an easier task by allowing the
installer to “home-run” all keypad cables. Plus, the MRCKPSP comes with an additional IR receiver
input/output connection.
The MRCKPSP can be used with the following products.

BASIC INSTALLATION - MRC44, MRAUDIO4X4, BXAUDIO4X4
The MRCKPSP is designed to easily connect two keypads in a zone. Figure 1 shows a
recommended application. The power jumper must be set to “INT”. This enables the multi-room
controller to power the primary and secondary keypads.

between the MRCKPSP and the multi-room controller is less than 15 feet.
