INSTALLATION INSTRUCTIONS
Description:
The passive infrared sensors work by detecting the difference between heat emitted from the human body in motion and the
background space. The sensor switch can turn a load ON and hold it as long as the sensor detects occupancy. After no motion is
detected for the set time delay, the load turns OFF automatically. The sensor switch has one relay (equal to single pole switch), it
also includes Ambient Light Level Sensor.
Coverage Area:
The coverage range of the sensor switch is specified and illustrated in Figure 1. Large objects and some transparent barriers like
glass windows will obstruct the sensor’s view and prevent detection, causing the light to turn off even though someone is still in the
detection area.
LOCATION/MOUNTING
Since this device responds to temperature changes, care should be taken when mounting the device.
DO NOT mount directly above a heat source, in a location where hot or cold drafts will blow directly on the sensor, or where
unintended motion will be within sensor’s field-of-view.
INSTALLATION
1. Connect lead wires as shown in WIRING DIAGRAM (see Figure 2): Black lead to Line (Hot), Red lead to Load
wire, White Lead to Neutral wire, Green lead to Ground.
2. Gently position wires in wall box, attach sensor switch to the box.
3. Mount device “TOP” up.
4. Restore power at circuit breaker or fuse, wait one minute.
5. Remove the small cover plate. (Illustrated as Figure 3.)
6. Locate the adjustment knobs on the control panel to perform test and adjustments.
(Illustrated as Figure 4.)
7. Replace the small cover plate after testing and adjusting.
8. Attach the wallplate.
NOTE: If twist on wire connector is provided, use to join one supply conductor with one 16 AWG device control lead.
ADJUSTMENT
Time Delay Knob
Default position: 15 Seconds (Test mode)
Adjustable: from 15 Seconds to 30 Minutes (clockwise)
Sensor Sensitivity Range Knob
Default position: Center at 65%
Adjustable: 30% (Position 1) to 100% (Position 4)
Note: Turn clockwise for larger rooms. Turn counter clockwise to avoid false alerts in smaller rooms or near
doorway or heat source.
Ambient Light Level Knob: Default position: Daylight (100% at position 4)
Adjustable: Daylight to 30 Lux (Counter clockwise)
OPERATION
Band Switch
Push-button:
As illustrated in Figure 5, the Load stays OFF when the button is pushed in and locked. (switched OFF) As illustrated in Figure 6,
the Load turns ON after the button is pressed and released. The sensor switch stays at the AUTO Mode until the button is pressed
OFF next time.
