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 ar-
eas where CFL lighting and indirect sunlight are present. You should avoid locating the WS120 near
potential sources of electrical or optical noise, such as light dimmers or low-voltage lights. Avoid
locating the WS120 near any potential sources of electrical or optical noise, such as light dimmers,
low-voltage lights, and neon lights.
AvOIdING OpTICAL FEEdBACk
If installing the WS120 in the same room as an IR flasher, it is possible for the flasher’s IR output
to be picked-up by the WS120. This effect, known as an optical feedback loop, can cause erratic
operation. Optical feedback is similar to acoustical feedback: the howling or whistling sound heard
in a P.A. system when the microphone is too close to the speaker. To avoid optical feedback:
1. Re-position the flasher(s) and/or the sensor.
2. Use Niles MF1 or MF2 flashers and cover them with the supplied IR blockers.
