MRC88 KEYPAD FEATURE DESCRIPTIONS
Figure 4 – The Model MRC88 Keypad – Front Panel Features and Functions
MRC88 KEYPAD - FRONT FEATURES:
1. MRC88 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 MRC88
system. A Programmable Learning Remote such as the Xantech URC2 is recommended for integrating the
IR commands of the MRC88 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) LED Off = Zone OFF
b) Steady Green = Zone ON
c) Slow Green Blink = Zone MUTE

  • Page 5: Mrc88 Controller/Amplifier Physical Location And Mounting

    MRC88 CONTROLLER/AMPLIFIER PHYSICAL LOCATION AND MOUNTING (BASIC/ADVANCED) When you mount the MRC88 Controller, you should plan its location carefully. Pay close attention to each of the following factors (refer to Figure 6A above): 1. The amplifier is convection cooled. That is, it depends on the natural free flow of air up through the slot perforations in the bottom plate, over the internal heat dissipating fins, then out the top cover, for adequate cooling.

    3. If the cabinet contains other heat generating components or you are using several MRC88's in a large multi- zone system, you will have to pay even closer attention to adequate ventilation.

    Figure 9 – Removing the MRC88 Keypad from the wall 1. Insert the MRC88 keypad removal tool into the slot at the bottom of the keypad, as shown in Figure 9, 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.

    Plug the supplied 283M IR emitters into the appropriate IR Emitter jacks - Figure 3-(26). Be careful to match the source audio and video connection number on the MRC88 to the IR Emitter jack number. This will ensure that the IR control signal will be routed to the correct source component. Find the IR sensor window on the source component and attach the emitter to the components sensor window after removing the protective paper cover on the flat side of the emitter head.

  • Page 11: Zone Related Wiring Connections

    ZONE RELATED WIRING CONNECTIONS In typical applications, each zone will have at least one MRC88 Keypad and a pair of stereo speakers. In those zones with both audio and video, at least one video monitor or television will also be used. In order to make these connections, the minimum requirement is home runs of one CAT5 cable for each zone’s...

    Using a 3.5mm mono mini phone connector, this control can be used to close relays (Xantech CC12) or turn on an AC outlet (Xantech AC1, AC2) for activity common to the system. Connect one end of the 3.5mm Mono Mini jack and the other end to the device to control. Tip=Control Voltage; Sleeve=GND...

    The STATUS line is an output and is active Hi (+12VDC) when the MRC88 Keypad is powered ON and is LOW (0VDC) when the Keypad is OFF. Use this to provide Bank Tracking LED on the SMARTPAD/WATERPAD keypad or other.
  • Page 16 Model MRC88 / MRAUDIO8x8 Extended Runs and Secondary Keypads In Zone Figure 11 – MRC88 Keypad CAT5 Cable Lengths The maximum cable length for CAT5 connections to a single keypad is 500 feet (see Figure 11-A). For two keypads in a zone, the distance to the last keypad is cut in half to 250 feet (see Figure 11-B). This same relationship applies to systems with 4 Keypads in the zone (Max distance to last keypad is 125ft.).
