Time Delay: Switches 4, 5, 6
The sensor will hold the lights on as long as occupancy is detected. The time
delay countdown starts when no motion is detected. After no motion is detected
for the length of the time delay, the sensor will turn the lights off. The sensor
can select the time delay using SmartSet, or you can select a fixed time delay.
• SmartSet records occupancy patterns and uses this history to choose
an optimal time delay from 5 to 30 minutes. SmartSet behavior starts
immediately and is refined continually as history is collected.
Walk-through mode turns the lights 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 selected time delay applies.
LEDs
When enabled, the red PIR and green Ultrasonic Activity LEDs on the sensor
will light when the associated sensor detects motion.
PIR Sensitivity
• Minimum forces a reduced detection range for the PIR.
• Max./SmartSet causes the DT-355 to monitor the controlled environment
and automatically select the maximum sensitivity that will provide reliable
operation without false detection. This setting is constantly updated.
