Introduction The Niles WS120 is a wall-mount, Decora® style IR sensor designed for use with the Niles infrared extender systems. Installed in a remote room location, the WS120 receives the IR commands transmitted from your existing hand-held remotes in that room. The commands are carried via a CAT-5 cable to your A/V equipment in another room, and instantly “repeated”. The WS120 is compatible with all current Niles infrared systems.
FEATURES AND BENEFITS The WS120 offers a number of improvements over other wall-mount IR sensors.
INSTALLATION CONSIDERATIONS The WS120 is a Decora-style module and is designed to use standard Decora-style cover plates and mounting hardware. Decora cover plates (up to 6-gang) with color-matched plate screws are available from your Niles dealer. TOOLS REQUIRED • 1/8” Standard Slotted Screwdriver • 1/4” Standard Slotted Screwdriver • Wire Stripper Type of Cable The WS120 connects to the Niles infrared main systems unit or IRH610 sensor expansion hub with an individual home run of CAT-5 cable.
INSTALLATION CONSIDERATIONS (continued) Receiving Range and Pickup Angle The receiving range of the WS120 will vary according to the IR output strength of the remote control being used. Remote strength varies among brands depending on the number and size of batteries used, and how many IR emitters the remote has. For example, remotes that operate on two small AAA batteries and have only one IR emitter are generally not as strong as remotes that use the larger AA size batteries and have two emitters.
INSTALLATION CONSIDERATIONS (continued) the WS120. If you must locate the WS120 near electrical devices, install it in a separate metal electrical box, ground the box to the electrical system ground, and route the WS120 cable several feet away from all electrical wiring. Avoiding Interference The WS120 is designed to work in most applications including plasma and LCD displays and in areas where CFL lighting and indirect sunlight are present.

INSTALLATION CONSIDERATIONS (continued) Using the WS120 with Niles MultiZone Keypads The WS120 is fully compatible with the Niles MultiZone Keypad that have an IR-Sensor connection, follow the wiring instructions in Figure 4. For specific information see your Niles MultiZone Keypad manual. Figure 4 T his color code is based on the industry standard T568A coding for the RJ45 connector.
INSTALLATION If you are installing the WS120 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 conduit, etc. 1. Locate the connector plug. 2. Strip 1/4” of insulation from the end of each wire. 3. Use a small flathead screwdriver or your thumbnail to raise the locking tabs, exposing the holes on the removable connector plug. 4.
IOPERATION Operation of the WS120 is simple. Stand within the operational range of your WS120. Aim your hand-held remote at the WS120 and press the button for the desired command. Your IR command is instantly repeated to your A/V equipment. Green “Power Status” LED When the WS120 is correctly connected (as shown in Figure 1), the Green LED will stay lit as long as the preamp/receiver is on. When your preamp/receiver is off, the LED will stay off.
TROUBLESHOOTING This manual contains instructions for the WS120 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). The bi-color blue/green LED on the front of the WS120 is a useful troubleshooting aid. The led should light solid green when status is detected. The blue LED should light only when a remote command is being received.
TROUBLESHOOTING (continued) Eliminating optical feedback In some installations, two conditions combine to create an optical feedback loop. Symptoms can include: poor range, intermittent operation or no operation. The conditions which sometimes combine to create a feedback loop are: 1. Both a sensor and a flasher are located within the same room. 2. There is some low-level noise or interference on your system.
TROUBLESHOOTING (continued) IR Test LED Off: Optical Interference IR Test LED On or Flickering: Electromagnetic Interference EMI (Electromagnetic Interference) Identify the source of the interference. The most common sources of electromagnetic interference are listed in the Installation Considerations section on page 5. To eliminate EMI try the following methods: 1. Move the sensor or the sensor cable away from the EMI source or move the source of the EMI away from the sensor or the cable. 2.
