Questions & Answers

Questions & Answers

What is the IP rating of DT-#100 series?

Asked by: Anonymous
We do not have a DT-100 sensor, if your question concerns the DT-305, this device is specified for indoor use only and does not have an IP rating.

Is it possible to have one sensor control two power packs? If yes, is there a wiring diagram of how this is accomplished?

Asked by: Jason
Jason, Yes You will use only one RED from the LV side of the power packs and cap the other. Then wire the following two wires in parallel, Blue - control output and Black - common.

I would like to use this occupancy sensor only to control HVAC via the external contact not lighting. Is it possible to connect 24V power directly to the sensor and avoid using the battery pack?

Asked by: Joe
Yes, the sensor can be powered via another 24V source, but it there's any question as to the voltage level or stability of the external source, we would recommend using one of our power packs.

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.
