Alerts
The DSW can provide audible alerts as a warning before the load turns OFF.
High
(DIP #4 OFF)
Default setting. Suitable for most applications.
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.
Time Delay
(15 min.
DIP 1 ON & 2 OFF)
Time delays of 5,
15
(default), or 30 minutes are
available. See DIP SWITCH SETTINGS for information.
Test/20 min
(DIP 1 & 2 OFF)
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.
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.
Low, 50%
(DIP #4 ON)
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.
Audible Alerts
(DIP #7 ON)
No Alerts
No warnings provided.
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.
Walk-Through
Mode
(DIP #3 ON)
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.
No Walk-Through
Walk-Through mode disabled.
Shading indicates default operation.
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,
both relays use the same delay.
