DESCRIPTION AND OPERATION
The DW Dual Technology Multi-Way Wall
Switch sensors combine advanced passive
infrared (PIR) and ultrasonic technologies
into one unit. The combined technologies
help to eliminate false triggering even in
difficult applications.
• The DW sensor has Multi-Way
available on all models.
• A “walk-through” mode can turn lights
off after only 3 minutes, if no activity is
detected after 30 seconds following an
occupancy detection.
• The DW-311 has one relay with
dimming control capability and two
buttons to allow control of the dimming.
• DW sensors contain a light level
sensor. If adequate daylight is present,
the sensor holds the load OFF until
light levels drop, even if the area
is occupied. See the Light Level
Adjustment section.
WARNING: TURN THE POWER OFF AT THE
CIRCUIT BREAKER BEFORE WIRING.
INSTALLATION
1. Make sure that the power has been turned OFF at the circuit breaker.
2. Connect wires to the DW flying leads as shown in the wiring diagram
that is appropriate to the DW model and electrical supply. The ground
wire (green) must be fastened to ground for the sensor to work
properly.
3. Attach the sensor to the wall box by inserting screws into the two wide holes on the
top and bottom of the attached metal bracket. Match them up with the holes in the wall
box and tighten. Do not use excessive force when installing the sensor into the
wallbox. Doing so can bend the mounting strap which can affect button operation.
4. Turn the circuit breaker ON. Wait one minute, then push the Auto ON/OFF switch and
the lights will turn ON. There is a delay due to initial power-up of the sensor that only
occurs during installation.
5. Test and adjust the sensor if necessary.
6. Install industry standard decorator wall switch cover plate (not included).

Troubleshooting

Lights Do Not Turn ON with Motion (LED Flashes)

Addresses issues where lights fail to turn on despite the PIR LED flashing, checking wiring and ON mode.

Lights Do Not Turn ON with Motion (LED Does Not Flash)

Troubleshoots lights not turning on when motion is detected and the PIR LED is not flashing, checking sensitivity and line.

Lights Do Not Turn OFF

Provides steps to diagnose why lights do not turn off, including checking time delay and sensor placement.

Sensing Motion Outside Desired Areas

Offers solutions for unwanted motion detection, suggesting lens masking and sensitivity adjustments.

Red LED is OFF

Diagnoses the issue of the red LED being off, indicating potential problems with Service Mode or Time Delay settings.
