  • Page 2: Unit Description And Operation

    UNIT DESCRIPTION AND OPERATION The DW-100-24 Dual Technology Low Voltage Wall Switch sensor combines advanced passive infrared (PIR) and ultrasonic technologies into one unit. The combined technologies help to eliminate false triggering even in difficult applications. Selectable operating modes allow the sensor to turn a load ON, and hold it ON as long as either or both technologies detect occupancy.

  • Page 3: Time Delays

    Time Delays The DW-100-24 holds the load ON until no motion is detected for the selected time delay. Select the time delay using DIP switch settings. In the DW-200, both relays use the same delay. Test/20 min A Test Mode with a short time delay of five seconds is set when DIP switches 1 &...

  • Page 4: Trigger Mode

    Trigger Mode The DW sensor has four occupancy trigger options, set with DIP switches 5 and 6. Determine the appropriate option using the Trigger matrix. In the Trigger Mode DIP switch setting table, in order to deem the area occupied: •...

    2. Check the wire connections, in particular, the Neutral and Line connections. Verify that connections are tightly secured. 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 and 2 to OFF to start Test Mode.
