Questions & Answers

Questions & Answers

Can I use a 4 square box with a single gang mud ring to mount DT-300 ceiling sensors & LMDC-100 occupancy sensors?

Asked by: Jeff
An Octagonal J Box is recommended for the DT-300. A standard Single Gang box is appropriate for an LMDC-100. (Please note these 2 devices are not compatible with each other.)

I have an existing system with BT-150 power packs, DT-300 Ceiling Mount Occ Sensors, and LP8 Panel. I am looking to add dimming wall switches to this system. What part numbers do I need? Can this be a wireless switch programmed to the sensor?

Asked by: Dan
Hi Tier 1 Tech Support - thank you for responding. I mistakenly said dimming. I do not need dimming switches I am just hoping to find wireless switches so that i can program them to the existing DT-300 occ sensors without opening up walls/ceilings.

I want to use the internal isolated (DT300) relay output 24VAC/Vto signal occupancy vs non-occupancy to my controller. however, the controller has 0-5, 0-10 VDC, 4-20mA, and dry contact inputs.please let me know how to match output to controller input?

Asked by: CuriousMatt
The isolated relay on the DT-300 is a dry contact which I would recommend you to use unless your controller need voltage. If you are needing more It would be best to contact Wattstopper Tech Support at 1-800-879-8585 option#1 for us to gather more information to help resolve your issue.

Can the DT-300 sensor be wired to have sensor turns lights on and 0-10V dimmer switch controls light output?

Asked by: Anonymous
Hello Mark, The configuration you have requested is possible if the Sensor is wired to the 0-10v dimmer first, followed by the dimmer being wired to the light fixture driver. *A potential delay can occur with the lighting fixture turning on/off via this configuration. Please feel free to give us a call if you need further assistance. legrand Contact information: Phone #: 844-957-3783 - Option 1, followed by option 2 for Technical Support.
