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 number of seconds indicated turns the lights back ON. If
the load was turned ON with the ON/OFF button, the re-trigger time is 30 seconds.
COVERAGE PATTERNS
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.
