can this dim 0-10 volt drivers or is it just adjusting sensor to preset hi and low trim levels. I need to be able to dim from 100 down to about 5% if needed.

Asked by: mike

Hello, The FS-205 occupancy sensors turn lighting ON and OFF based on occupancy and ambient light levels. It does not have continues dimming

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.

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?

Asked by: Steven Schmelz

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.

Are these occupancy sensors exterior rated? If not, what occupancy sensors are?

Asked by: Enrica Cotellessa

The Wattstopper CI-305 is not exterior rated. For outdoor applications, I recommend looking into the FSP line of sensors, which are designed for outdoor use.

Has this item been discontinued?

Asked by: David

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.

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
