Questions & Answers
My lights are not automatically turning off. Does this mean the sensor has gone bad or would a bad sensor not allow the lights to turn on at all
Hello,
we may need to troubleshoot to determine if there indeed is a component issue. Simply start with disconnecting the blue control output wire on the back of the sensor - it is low voltage. If the lights turn off when this is done the power pack is fine - possible sensor issue. If lights remain ON when the wire is removed - power pack needs to be replaced.
Please call us if further assistance is needed, 1-800-879-8585 opt 3

can I wire these together so that when one area comes on they all come on. I have 3 currently servicing a barber shop. when 1 area comes on I want them all to come on, Is this possible with the DT 305? If so how?
Hello,
It sounds like we have three separate power packs, we can use one power packs red/blue/black and the other two packs we will cap the red 24v off and in parallel connect the blues and blacks.

Has this item been discontinued?
Hello David,
I have checked our inventory, and discontinued list. The DT-305 is not an obsolete item, and is available

I have 3 occupancy sensors that do seem to shut off the lights when unoccupied. I see the red and green light flickering meaning we clearly have power.
The red and green are activity LEDs for the sensors, if the LEDs continue to flash when you stand still, then the sensor is likely false tripping. I suggest to start with placement, assure all sensors are 5-6' away from air supplies this is common to false trip the sensors causing lights to either stay ON or OFF.

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

I have a DT-305 and the two incandescent light fixtures that it controls are blinking on and off constantly. Is this a defective sensor or power pack issue?
Please reach out to our tech. support team for further assistance troubleshooting this issue.

Does the sensor provide data as to how often the area is occupied?
Hi Eric,
Sorry but no the sensor does not provide that data with this model.

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