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. Tests with various manufacturers’ remote controls
have shown that the operating range can vary from a minimum of 20’ to a maximum of about 35’.
Infrared signals travel essentially line-of-sight. They will not pass through or around solid objects.
Do not rely on an IR signal being able to “bounce” off a wall or object to the WS120. The IR pickup
angle of the WS120 is 30° off-axis (horizontal and vertical) at 25’.
JUNCTION BOxES
The mounting depth of the WS120 is 1-1/4”. When installed, the unit extends 3/4” behind the
sheetrock wall (assuming 1/2” sheetrock). Suitable electrical boxes are available from your Niles
dealer or local electrical supply company.
dO NOT INSTALL ThE WS120 INTO ELECTRICAL BOxES WITh 110 vOLT dEvICES.
Some states or municipalities allow devices such as the WS120 to be installed into the same
electrical box as 110 volt devices, provided a “low-voltage partition” is used between the devices.
We do not recommend this. The cable connected to the WS120 can act as an “antenna” for
electrical noise. Locating the WS120 cable too close to a light dimmer or switch may interfere with
