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

Asked by: jon

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

I have a DT 300 sensor. Can I keep my lights on all the time during business hours without movement. I only see a 30-minute delay, was looking for an 8-to-9-hour delay

Asked by: larry

The maximum delay time on a DT-300 sensor is 30 minutes.

I work as a maintenance tech at a school. A student has removed the faceplate from the sensor. Is there a replacement faceplate available?

Asked by: Mark

Wattstopper does not sell a replacement for the faceplate, but the Technical Support Department may be able to help. Please contact Technical Support at 800-879-8585 and one of our technicians will be happy to assist.

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,
