Questions & Answers

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

Asked by: greg
It is recommended that you chose one or the other. The sensors will not work in conjunction with each other.

I have 3 x 301's in a row. please post a wiring diagram for more than 2 devices in a row. Also when should use the walk thru mode ?

Asked by: dale
We do not have a diagram that shows more than 2 sensors. You should connect the primary switch, install the second per the diagram and then mirror the same with the remaining 2 switches. A short hallway that is not used often or a storage closet application are places where Walk through mode may be appropriate.

Can this be use on one side of a 3 way system with the other switch a regular 3 way>

Asked by: cody
Hello Cody, The DSW301 Occupancy sensor supports Multi-way functionality for use with additional DSW301 sensors. The DSW301 will not work with a traditional 3-way switch and must be paired with another DSW301 for 3-way applications. Best Regards, Technical Support
