COVERAGE PATTERNS
The WS detects motion in areas up to 900 sq. ft. and up to 35 feet from the sensor. Ideally,
the sensor is designed for small amounts of motion in spaces up to 300 sq. ft. The Fresnel
lens on the sensor is a multiple segment viewing lens with a field of view of 180°.
The sensor must have a clear view of the people in the space in order to detect occupancy.
Obstructions, such as furniture blocking the sensor’s lens, may prevent occupancy
detection.

MASKING THE LENS
Opaque adhesive tape is supplied so that sections of the sensor’s view can be masked. This
allows you to eliminate coverage in unwanted areas.
Since masking removes bands of coverage, remember to take this into account when
troubleshooting coverage problems.

INSTALLATION
WS Wall Switch
Wall Junction Box
1. Connect the existing wires in the wall box to the sensor flying leads. (See Wiring Directions at right).
• Do not allow bare wire to show below connector.
• The ground wire must be tightly grounded for the unit to operate properly.
2. Attach the sensor to the wall by mounting it in the wall box with the two mounting screws provided.
3. Turn ON power at the circuit breaker.
4. Test the sensor using the procedure in the Sensor Adjustments section.
• There is an initial warm‑up period after installation. It may take up to a minute before the load turns ON due to a sensor
warm‑up period during initial power‑up (this occurs during installation only). The load turns ON after the warm‑up period ends if
the sensor detects motion.
• Rapid successive pressing of the ON/OFF button causes a delay in function. A single press of the button causes an immediate
response. If the button is pressed again within 2 seconds, the switch ignores it. Wait at least two seconds between button
presses.
5. Install industry standard decorator wall switch cover plate (not included).
CAUTION: TURN THE POWER OFF AT THE CIRCUIT BREAKER BEFORE INSTALLING THE SENSOR.
