Rated 1 out of 5 by from horrible for office setting This is horrible for an office setting if you work at a computer or are required to read/write for extended periods. The lights constantly turn off, requiring you to get up to turn the lights back on.

If the switch is not working on motions how do you set it to do so

Asked by: Bobby
Hi Bobby, To set this switch to auto on when you enter, you have to put dipswitch 8 in the down/off position to enable auto on.

Replaced sensor switch w/DSW-301. Connected line to blk, grn to ground, capped ylw, and load to combo of blu/wht, red, neutral. Load is 120-wt LED driver. PIR flashes red, device "clicks" on/off, but no power to LED driver. how to diagnose?

Asked by: Jerome
Hi Jerome, I suggest giving the wiring another look. You mentioned the load is connected to a combination of blue with white striped wire, red, and neutral. The wiring should be as follows: Black > Power from your Service Panel Red > Load wire to be connected to your fixture Yellow > Traveller Wire (to be capped if used as a single pole switch) Green > Ground Blue with White Stripe > Connect to the Neutral (If there is no neutral present, connect along with the ground wire) I would verify functionality at this point.

Does holding the button down for 10 seconds return this to operation as a regular light switch that ONLY works with manual button press? NO motion/light control or auto-off?

Asked by: Matthew
No, to put the switch/sensor into Service Mode (where it will function like a manual switch), simply turn the Ultrasonic Sensitivity trimpot to Minimum.

DSW-301,  instructions don’t show a wiring diagram with a three way switch, will it not work that way or do have to have 2 -301 devices?

Asked by: Zach
Hello, The DSW-301 supports multi-way wiring, which requires multiple DSW-301 ( up to 4 sensors) to complete a 3-way configuration. Best Regards, Justin
