  • Page 2: Unit Description And Operation

    UNIT DESCRIPTION AND OPERATION The UW Ultrasonic Wall Switch sensors employ 40kHz ultrasonic technology in a single-gang wall switch unit. The UW sensor can turn a load ON, and hold it ON as long as the sensor detects occupancy. After no movement is detected for the selected time delay, the lights switch OFF.

  • Page 3: Time Delays

    Presentation Mode is a feature of the Auto ON mode.When both relays are manually turned OFF the UW holds the lights OFF until no motion has been detected for the duration of the Time Delay. With subsequent occupancy, the UW turns the load ON.

  • Page 4: Audible Alerts

    Visible Alert The UW sensor can provide a visual alert as a warning one minute before the load turns OFF. Visible (DIP #5 ON) 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.

  • Page 5: Installation

    INSTALLATION WARNING TURN THE POWER OFF AT THE CIRCUIT BREAKER BEFORE INSTALLING THE SENSOR OR WORKING ON THE LOAD. 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 below that is appropriate to the UW model and electrical supply.

  • Page 7: Sensor Adjustment

    ADJUSTMENTS Sensor Adjustment Remove the wall plate. Remove the button cap by firmly squeezing together the top sides of the button assembly. Gently pull it away from the unit. When the adjustments are completed, replace the button cap by inserting its hinges into the tabs on the main unit and then squeeze the top of the button while pressing it into the unit.
  • Page 8 3. If lights still do not turn ON, call 800.879.8585 for technical support. Lights do not turn OFF 1. There can be up to a 30 minute time delay after the last motion is detected. To verify proper operation, set DIP switch 1 to ON, then reset switches 1, 2 and 3 to OFF to start Test Mode.
