Presentation Mode
Presentation Mode is a feature of the Auto ON mode.When both relays are manually turned OFF the DSW holds the lights OFF until no
motion has been detected for the duration of the Time Delay. With subsequent occupancy, the DSW turns the load ON. If both relays are
ON and one relay is manually turned OFF this relay remains OFF until both the Time Delay and retrigger delay expires for the relay that
is ON, after that time the ON Mode control settings again apply.
Time Delays
The DSW sensor holds the load ON until no motion is detected for the selected time delay. Select the time delay using DIP switch
settings. In the DSW-302-347, both relays use the same delay. See DIP SWITCH SETTINGS for more information.

(DIP 1, 2, OFF)
Time Delay
(15 min. DIP 1 ON & 2 OFF)
Walk-Through Mode
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.
Walk-Through Mode
(DIP #3 ON)
No Walk-Through
(DIP #3 OFF)
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.

(DIP #4 OFF)
Low, 50%
(DIP #4 ON)
Alerts
The DSW can provide audible alerts as a warning before the load turns OFF.

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 require 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
5 seconds turns the lights back ON. If the load was configured as Manual ON, the re-trigger time
is 30 seconds.

A Test Mode with a short time delay of five seconds is set when DIP switches 1 & 2 are OFF. It
cancels automatically after ten minutes, or when you set a fixed time delay. When the Test Mode
times out, the sensor will assume a 20 minute time delay. To restart Test Mode, change the time delay
setting to any fixed amount and then return it to the Test setting.
Time delays are 5, 15, or 30 minutes are available. The default is a 15 minute delay.
The DSW sensor turns the load OFF 3 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. This is the default.
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.
