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.

Asked by: Serge St Pierre
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. If more assistance is needed, please call our Technical Support Team 1-800-879-8585

Is there a diagram that shows how a LVSW-104 connects to a LC8 and a DT-300 and so on? This is beyond frustrating trying to find a diagram that shows how this system is actually wired. Makes one want to use Leviton!!!

Asked by: DennisB
Yes, please refer to page 15 and 16 of the LC8 User Manual which shows connectivity for switches and sensors . The LVSW-104 contains 4 separate 2 Wire Momentary switches, so you will follow the diagram for '2-Wire Momentary Push Button' connections. The LC8 User Guide can be found here: https://www.legrand.us/lighting-controls-and-systems/lighting-control-panels/stand-alone-panels/lc8-lighting-control-panel-includes-lcps-120-277y/p/lc8-120-277 If you need additional assistance, please call our Technical Support department at 800-879-8585,

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.
