Xantech MRCKPSP Installation Instructions

Multi-room controller, keypad splitter

INSTALLATION INSTRUCTIONS

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.

►MRC44CTL

►MRC88CTL

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.

The primary keypad must have both the "secondary" and "zone termination" jumpers removed. The

secondary keypad must have both the "secondary" and "zone termination" jumpers installed. The

distance between the MRCKPSP to the MRC44 Keypads is 250 feet maximum. The distance

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