Walk-Through
The Walk-Through mode shortens the time delay to reduce the amount of time the load is ON after a brief moment of occupancy, such
as returning to an office to pick up a forgotten item then immediately exiting.

Coverage testing has been performed according to he NEMA WD 7 guideline. For best
performance, use in spaces not larger than 15' x 15'.
Ultrasonic Sensor
The sensor has two ultrasonic transceivers operating at 40kHz. Detection sensitivity can be
adjusted using the trimpot under the ON/OFF buttons.
1. Make sure that the power has been turned OFF at the circuit breaker.
2. Connect wires to the UW flying leads as shown in the wiring diagram
that is appropriate to the UW model and electrical supply.
3. Attach the UW to the wall box by inserting screws into the two wide
holes on the top and bottom of the attached metal bracket.
4. Match them up with the holes in the wall box and tighten.
5. Turn the circuit breaker ON.
6. Wait one minute, then push the ON/OFF button for each load and the
lights will turn ON.
7. Test and adjust the sensor if necessary.
8. Install industry standard decorator wall switch cover plate (not included).
A Test Mode with a short time delay of 5 seconds is set when DIP Switches 1, 2, & 3 are OFF. It cancels
automatically after ten minutes, or when you set a fixed time delay. When the Test Mode times out, the
sensor assumes a 20 minute time delay. To restart Test Mode, change the time delay setting to any fixed
amount and then return it to the Test setting.
Time delays are 5, 10, 15, 20 (default), 25, or 30 minutes.
The UW sensor turns the load OFF 3 minutes after the area is initially occupied, if no motion is detected
after the first 30 seconds. If motion continues beyond the first 30 seconds, the set time delay applies.
Walk-Through mode disabled.
When only one minute is left in the time delay, the load connected to the relay turns OFF for one second.
This provides a one minute warning before the load(s) are turned OFF by the sensor.
No visual alert for delay expiration warning.
Unit will beep at one minute*, at 30 seconds and at 10 seconds before turning OFF load. When Walk-
Through is active, the unit beeps three times at 10 seconds before the load goes OFF.
*If Visual Alert is also ON, the one-minute time-out warning beep is replaced by the visual alert.
No warnings provided.
