1. MRC44 Keypad.
2. Power. Turns the zone ON and OFF. Can be programmed with IR
codes or sequences.
3. IR Sensor. Receives IR from hand-held remotes to control both source
components and the MRC44 system. A Programmable Learning Remote
such as the Xantech URC2 is recommended for integrating the IR
commands of the MRC44 and source components into a single
controller. Compatible with most brands of remote controls, though some
may not be programmable and will therefore only control the source
components.
4. Status Indicator LED. Will indicate zone/system status and will flash as
IR is received at the IR Sensor. These indicators, one for each Keypad,
provide the following Information:
a) Off=Zone OFF
b) Steady Green=Zone ON
c) Flash Green=Zone MUTE
d) Flash Red=IR Sensor INPUT or Keypad OUTPUT
e) Flash Amber=System BUSY
5. LCD Display. When the zone power is ON, the LCD will indicate the
selected source, zone and system status, zone volume level and other
system conditions. The display is automatically backlit when any button
is pressed.

6. Source 1 Selector. Selects source input 1, reverses source icon on LCD
Display when source is selected and sends IR commands programmed
to this button (if any) to the source 1 and common emitter outputs. Also
used in Dynamic Monitor Lockout and Dynamic Zone Link Modes.
7. Source 2 Selector. Selects source input 2, reverses source icon on LCD
Display when source is selected and sends IR commands programmed
to this button (if any) to the source 2 and common emitter outputs. Also
used in Dynamic Monitor Lockout and Dynamic Zone Link Modes.
8. Source 3 Selector. Selects source input 3, reverses source icon on LCD
Display when source is selected and sends IR commands programmed
to this button (if any) to the source 3 and common emitter outputs. Also
used in Dynamic Monitor Lockout and Dynamic Zone Link Modes.
9. Source 4 Selector. Selects source input 4, reverses source icon on LCD
Display when source is selected and sends IR commands programmed
to this button (if any) to the source 4 and common emitter outputs. Also
used in Dynamic Monitor Lockout and Dynamic Zone Link Modes.
10. Vol

11. Vol -.Decreases zone volume and moves the Volume Bar on the LCD
Display to indicate volume level (non-programmable).
12. Mute. Mutes zone speaker output. Sends IR commands programmed to
this button (if any) to the selected source and common emitter outputs.
13. CH
+. Sends IR commands programmed to this button to the selected
source and common emitter outputs.
14. CH
-. Sends IR commands programmed to this button to the selected
source and common emitter outputs.
15. Status. Displays zone and system status (zone/source activity, linked
zones, audio setup, etc – non-programmable).

keypad in a zone. If there are two keypads in a zone, remove only from
the first keypad.
21. Enable Sensor. Jumper. Enables IR sensor on Keypad. Remove when
using an external IR receiver.
22. IR Sensitivity Adjustment. Carefully adjust for background light level to
prevent false triggering of the IR circuits. Slowly turn counter-clockwise
to reduce sensitivity.
23. LCD Backlight Adjustment. Adjusts brightness of LCD backlight. This

Keypad mounting for the MRC44 Keypad does not require a junction box.
The MRC44 keypad can be mounted on drywall, lath & plaster, button board
or other surfaces covering a hollow wall. Follow these simple procedures to
install the provided MRC44 mounting bracket and keypad:
1. Cutting the hole
a. Mark the desired mounting location for the center of the keypad.
b. Using a level, make proper horizontal and vertical marks on surface
to be cut, to properly orient template.
Figure 4 – MRC44 Keypad mounting template

Page 12 Model MRC44KP

c. Locate the provided template so that the mark is in the center of the
hole, which is in the center of the template.
d. Rotate the template around the center until the template is level.
e. Press or hammer the template in place so that the holding tabs
pierce the wall and hold the template in place.
f. Mark or scribe the outline of the template on the wall.
g. Remove the template and cut a clean hole through the wall along the
outline of the template, being sure that your cut is on the outline. Any
cut outside of the outline by more than ¼” may not be covered by the
keypad.

2. Installing the Mounting Bracket
a. Attach the ground wire to the ground lug to the rear of the back-bar
with the provided green screw, before beginning the bracket
installation process.
NOTE: A ground wire connected to Earth ground is required to
protect against static discharge.
b. Run the supplied screws through the top (marked on the front of the
bracket) of the mounting bracket into the back-bar as shown in
Figure 5.
c. Pull the CAT5 cable through the hole in the wall.
d. Pull the CAT5 cable through the hole in the mounting bracket.
e. Slide the left or right side of the back-bar into the wall.
f. Center the mounting bracket in the wall and tighten the screws until
the bracket is firmly held in the wall. Over tightening will distort the
bracket and prevent the Keypad from snapping tight against the wall.
Under tightening will cause the Keypad to be loose against the wall.
g. If there is not enough room to slide the keypad in as described
above, you can hold the back-bar in place as you run the screws
through the mounting plate and into the back-bar. TIE A LONG
STRING TO THE BACK-BAR so that you can easily retrieve it in
case you drop the back-bar into the wall!
3. With the Controller/Amplifier turned off, connect the CAT5 cable to the
appropriate RJ45 connector, using Figure 7 as a guide for CAT5
termination.
4. Add or remove jumpers on the rear of the MRC44 keypad-according to
Table 1 (Keypad connections).

5. Firmly snap the MRC44 Keypad into the bracket that you have just
installed (see Figure 3).
6. Confirm all Keypad operations.

1. Insert the MRC44 keypad removal tool into the slot at the bottom of the
keypad, as shown in Figure 6, being sure that the tool is inserted so that
the “insert to here” line slides under the Keypad. This will reduce the risk
of damage to the Keypad or the wall.
2. Twist the removal tool in either direction until the bottom of the Keypad
pulls away from the wall, then carefully grip the edges of the Keypad with
your fingers and pull it off the wall.
NOTE: Since the Keypad snaps into the mounting bracket and there are
a large variety of wall textures, the Keypad may POP OUT or require
some additional effort to pull it off the wall, depending on your particular
installation.

MRC44 Keypad Cable Connections at the MRC44 Controller/Amplifier
1. See Figure 7 for termination of the CAT5 cables to the RJ45 connectors.
2. Connect the zone keypad to the appropriate zone Keypad connector on
the rear of the MRC44 Controller/Amplifier.
CONNECTIONS AT THE ZONE LOCATION
Single Keypad Connections
1. Refer to Figure 7 for proper termination at the zone-end of the CAT5
cable.
2. Connect the CAT5 cable from the MRC44 Controller/Amplifier into the
RJ45 jack marked “Controller” on the rear of the MRC44 keypad.
3. Depending on the number of MRC44 keypads and IR receivers used in a
zone the jumper pins on the MRC44 keypad are to be connected as
shown in Table 1.
Multiple Keypad Connections
1. For a second keypad in the same zone, terminate the CAT5 cable with
the same configuration as shown in Figure 7.
2. Connect the CAT5 coming from the MRC44 Controller to the
“CONTROLLER” jack on the Primary Keypad. Plug a CAT5 cable into
the “EXPANSION” jack on the Primary Keypad and connect it to the
“CONTROLLER” jack on the Secondary Keypad. Set the jumpers
according to the above Table 1.
3. When adding an IR receiver in the zone, set the jumpers according to the
above table and connect the cables as shown in Figure 8.

The maximum cable length for CAT5 connections to a single keypad is 400
feet (see Figure 8A). For two keypads in a zone, the distance to the last
keypad is 200 feet (see Figure 8B).

Figure 9 – MRCCB1 MRC44 Connecting Block
If both keypads in the zone are using an external IR receiver, the MRC44
Connecting Block (see Figure 9) is used to expand the connections on
the back of the primary keypad as shown in Figure 8C.
If your installation requires cabling beyond these limits you can use the
MRC44 Connecting Block to power the keypads from a separate run of
+12VDC as shown in Figure 8D. The +12VDC can also be generated in
the zone from a model 782 power supply or from a source at the
Controller/Amplifier location (run an 18 gauge speaker wire to the
MRC44 Connecting Block to minimize line loss. This method will extend
the distance to the last keypad in the zone to a maximum of 1000 feet.
The Maximum cable run to the external IR receiver in each of the above
cases is 250 feet from the keypad.
