ADVANCE INSTALLATION – MRC44, MRAUDIO4X4, BXAUDIO4X4 & WPK Waterpad
An additional keypad device can be connected to the MRCKPSP. Figure 4 shows an application
where a WPK Waterpad is connected and used in the same zone as the two keypads. An external
power supply is used to power both primary and secondary keypads as well the Waterpad. The
power jumper must be set to “EXT”.

The keypads should follow the jumper settings as discussed in “BASIC INSTALLATION – MRC44,
MRAUDIO4X4, BXAUDIO4X4”.
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. The distance between the
MRCKPSP and the WPK Waterpad is 250 feet maximum.
Since an external power supply is being used, the system must be powered up in a specific
sequence. Apply power to the MRCKPSP before starting the MRC44 Controller.
