INTRODUCTION
The MRC44CB1 connecting block allows added flexibility for current MRC44 system owners in regard to Keypad placement. It
also provides for the addition of external IR Receivers and/or utilizing other Xantech IR Keypads on an existing MRC44
system (i.e. using SMARTPAD3 or WATERPAD Keypads in addition to or instead of, the standard MRC Controller Keypads).
FEATURES
• Add external Xantech IR Receivers in conjunction with MRC44 Keypads
• For Retro installs requiring J-Box style keypads only, allows integration of SMARTPAD3 or WATERPAD Keypads to an
existing MRC44 system
• Add outdoor Zone or Sub-Zone utilizing WATERPAD Keypad
• Extend maximum distance of Secondary Keypad to 600ft
• External Power Supply selector jumper. Enables use of external 12v supply for longer cable runs and applications requiring
higher current capacity supplies
• IR Receive confirmation LED
SPECIFICATIONS
• 1 – Three Terminal, Screw-Type connection for +12VDC, GND, and SIGnal from Xantech IR Receivers and IR Controller
Keypads
• 1 – 3.5mm mini stereo “Quick Connect” IR IN input jack
• 2.1mm coaxial power jack
• 2 – RJ45 connectors for connection to/from MRC Controller and MRC44 Keypad
• Max Distance powered from MRC44 Controller: 200ft as measured from MRC44 Controller to last keypad/IR Receiver in
line
• Max Distance powered fro external 782-00 PS: 600ft as measured from MRC44 Controller to last keypad/IR Receiver in
line.
• Dimensions: 3-½” W x 1” D x ¾”H

EXAMPLE A
SUBSTITUTING A SMARTPAD3, WATERPAD OR IR RECEIVER IN PLACE OF A MRC44 KEYPAD
This is desired if an outdoor zone keypad is required or if the keypad must be mounted in a standard J-Box
1. Remove Power Jumper (JP1) from MRC44CB1
2. Mount MRC44CB1 to a convenient location using the Adhesive strip supplied
3. Run a CAT5 jumper from the MRC44 Keypad output to the connector labeled Controller on the MRC44CB1
4. Run 3 conductor 22AWG cable (or higher) to desired keypad or IR receiver location
5. Connect one end of the 3-conductor cable to the V G S terminals of the MRC44CB1 connecting block and the other
end to the proper +12v, IR Out, and GND terminals of the desired Keypad or IR Receiver.
Note: Refer to applicable instructions supplied with Keypad or IR Receiver for proper wiring instructions.
6. Connect 781RG or 782-00 Power Supply (depending upon current load requirements) to MRC44CB1 2.5mm Coaxial
Jack
Caution! Make sure jumper JP1 On MRC44CB1 is removed before connecting Power Supply to connecting block.

SUBSTITUTING A SECONDARY SUB-ZONE MRC44 KEYPAD WITH A SMARTPAD3, WATERPAD OR IR RECEIVER
This is applicable if the Sub-Zone location is outdoors, requires a J-Box style mount, or if local speaker Mute is required.
1. Mount MRC44CB1 to a convenient location using the Adhesive strip supplied
2. From Primary MRC44 Keypad, run a CAT5 wire to the secondary location.
