Coverage Patterns; Installation - LEGRAND Wattstopper DSW-302 Installation Instructions Manual

Coverage testing has been performed according to the NEMA WD 7 guideline. For
best performance, use in spaces not larger than 18' x 15'.
PIR Sensor
The sensor has a two-tiered, multi-cell viewing Fresnel lens with 180 degree field of
view. The red LED on the sensor flashes when the PIR detects motion.
Masking the Lens
Opaque adhesive tape is supplied so that sections of the PIR sensor's view can be
masked. This allows you to eliminate coverage in unwanted areas. Since masking
removes bands of coverage, remember to take this into account when troubleshooting
coverage problems.
Ultrasonic Sensor
The sensor has two ultrasonic transceivers
operating at 40 kHz. Detection sensitivity
can be adjusted using the trimpot under the
ON/OFF buttons.
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. Reinstall the cover plate.
Light Level Adjustment
The light level can be set with loads ON or OFF. To enable light level control and set the threshold:
1. Make sure the room is lit appropriately.
2. Put the sensor into TEST mode (see Time Delay switches). You have 10 minutes to complete the procedure.
3. Press and hold the ON/OFF button (Relay 1 button on the DSW-302) for 3 seconds, until you hear a beep.
4. Step away from the sensor. After 10 seconds a beep sounds, indicating that the threshold level is set. This threshold is retained,
even if power is lost, until it is re-set or disabled. In the DSW-302, light level control only affects Relay 2. To disable light level
control, press and hold the Relay 1 button for 7 seconds until a double beep tone sounds.
Reset to Default
Use the DIP Switch Settings tables on the previous page to return features to factory settings. To reset the DSW, press and hold the
Relay 1 button for 10 seconds until a triple beep sounds. This resets the sensor and disables light level control (the brightest ambient
light will not hold the light OFF).
WARNING: TURN THE POWER OFF AT THE
CIRCUIT BREAKER BEFORE WIRING.
1. Make sure that the power has been turned OFF at the circuit breaker.
2. Connect wires to the DSW flying leads as shown in the wiring diagram that is appropriate to the DSW 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.
4. Turn the circuit breaker ON. Wait one minute, then push the Auto ON/OFF switch for each load 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).
