Questions & Answers
how do you adjust time delay
The time delay on the DSW-301M-W is adjusted using the DIP switches located behind the button cover.
The sensor keeps the load ON until no motion is detected for the selected time delay. You can set the delay as follows:
🔹Test Mode / 20 minutes (DIP 1 OFF, DIP 2 OFF):
Test Mode uses a short 5-second delay and automatically cancels after 10 minutes, or when a fixed time delay is selected. Once Test Mode times out, the sensor defaults to a 20-minute delay. To restart Test Mode, change the time delay to a fixed setting and then return it to the Test setting.
🔹15 minutes (DIP 1 ON, DIP 2 OFF):
This is the factory default setting.
Additional fixed time delays of 5, 15, or 30 minutes are available by selecting the appropriate DIP switch combination.
