INTRODUCTION FEATURES & BENEFITS The MS120 is aflush-mount IR sensor designed for use with the Niles infrared extender systems. The MS120 offers a number of improvements over other miniature IR sensors.
INSTALLATION CONSIDERATIONS Type of Cable The MS120 connects to the Niles infrared main systems unit or IRH61 0 sensor expansion hub with an individual home run of CAT-5 cable. When running wires inside walls, most states and municipalities in the U.S. specify that you must use a special type of wire. Usually, the requirement is that the wire has a specific "CL" fire rating, such as "CL-2" or "CL-3".
We do not recommend this. The cable connected to the MS120 can act as an "antenna" for electrical noise. Locating the MS120 cable too close to a light dimmer or switch may interfere with the MS120. If you must locate the MS120 near electrical devices, install it in a separate metal electrical box, ground the box to the electrical system ground, and route the MS120 cable several feet away from all electrical wiring.

INSTALLATION If you are installing the MS120 into an existing wall, take time to consider any possible obstructions which may be hidden inside the wall, such as wood or metal studs; electrical, telephone or other types of wiring; plumbing; AC or heating conduits; old wall safes; etc. 1. Determine a mounting location for the MS120. Select a location where you will have access to the rear of the MS120 after it is installed.
TROUBLESHOOTING This manual contains instructions for the MS120 only. For specific information on the adjustment and operation of your Niles infrared extender system, please refer to the instruction manual included with your Niles IR main system unit (MSU140, MSU250, MSU480 MSU440Z). ,. Test the remote control(s) by operating the AN equipment directly. Replace the batteries if needed. 2. Double check the cable connections on the MS120 and on the main system unit. Look for open, shorted or reversed wires. 3.
