LEGRAND Wattstopper DW-100-24 Manual De Instrucciones página 2

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.

PIR Sensitivity Adjustment
The DW-100-24 constantly monitors the controlled environment and automatically adjusts the PIR to avoid common ambient conditions
that can cause false detections, while providing maximum coverage.

Alerts
The DW can provide audible alerts as a warning before the load turns OFF.

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:
• Both requires motion detection by the PIR and the Ultrasonic.
• Either requires motion detection by only one technology.
• PIR requires motion detection by the PIR.
Initial Occupancy: The method that activates a change from "Standby" (area unoccupied and load
OFF) to "Occupied" (area occupied and load may turn ON).
Maintain Occupancy: The method indicating that the area is still occupied and the lights should remain ON.
Re-trigger: In Auto On Mode, after the load turns OFF, detection by the selected technology within the selected Time Delay turns the
lights back ON. If the load was turned ON with the ON/OFF button, the re-trigger time is 30 seconds.
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. You can eliminate coverage in unwanted areas. Since masking removes
bands of coverage, take this into account when troubleshooting coverage problems.
Ultrasonic Sensor
The sensor has two ultrasonic transceivers operating at 40kHz. Detection sensitivity
can be adjusted using the trimpot under the ON/OFF buttons.
Side View
The DW sensor turns the load OFF three 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.
Default setting. Suitable for most applications.
Reduces sensitivity by approximately 50%. Useful in cases where the PIR is detecting movement outside of
the desired area (also consider masking the lens) and where heat sources cause unnecessary activation.
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.
No audible warnings provided.
