PIR Sensitivity Adjustment
The DSW sensor constantly monitors the controlled environment and
automatically adjusts the PIR to avoid common ambient conditions that can cause
false detections, while providing maximum coverage.
High
(DIP #5 OFF)
Low, 50%
(DIP #5 ON)
Alerts
The DSW can provide audible alerts as a warning before the load turns OFF.
Audible Alerts
(DIP #7 ON)
No Audible Alerts
(DIP #7 OFF)
Trigger Mode
The DSW 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 configured as Manual ON, the re-trigger time is 30 seconds.

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. This is the default.
No audible warnings provided.
