Questions & Answers
One of the answers to a question asked previously was that a DT-355 Line voltage sensor could be combined with a Radiant 0-10V dimmer on the load side. Is this correct? I am about to order this combination of devices and I want to make sure.
Hello John,
Yes, you can utilize a radiant 0-10v dimmer on the load side of the DT-355 sensor. Please feel free to give us a call if you would like to discuss this configuration further.

Can a dimmer switch be incorporated with the occupancy sensor to dim the lights when needed?
Yes, a line voltage switch/dimmer can be added to the load side of the DT-355.

Do you have a sensor rated to 0F ?
The CB-100 is a PIR only sensor, which can operated -40 to 95F.
Please view attached SPEC sheet

What is the maximum distance the occupancy sensor can be from the ground for it to work properly
The DT-355 is designed for a ceiling heights of about 8-12 feet from the floor.

Does this sensor cover minor motion? If so, what are the distances for that?
The DT-355 is a Dual-Technology sensor that has both PIR and Ultrasonic technology built in . The sensor is able to detect major and minor motion up to 1000 sqft when mounted below 10'.

We have these thru out our warehouse, but would like the one by the entry door to stay on, is that possible?
To override all sensor functions on the DT-355, set the Ultrasonic Sensitivity trimpot to the fully counterclockwise (Service) position.
This bypasses the occupancy control functions of the sensor.

Hello, is the DT-355 sensor rated for exhaust fans?
No, the DT-355 has no rating for motor loads. I suggest looking at our BZ power packs and a 24v low voltage sensor. BZ power packs are rated for motor loads.

Comparing with the other product Ultrasonic Ceiling Occupancy Sensor, 24VDC (W-500A), which sensors would be more suitable for a 150sq.m classroom? Comparing to its technologies, lifetime and price. Thank you.
Dual technology sensors are most commonly used in this application. They work using a combination of PIR and Ultrasonic technology. As individuals move throughout a given space, Ultrasonic wave analysis and the Doppler effect help detect indirect motion while passive infrared sensors monitor presence directly.

we are looking for an occupancy sensor that will fit in a single gang electrical box. do you offer one?
Good Afternoon,
Thank you for contacting Wattstopper. We offer several sensor switch options that will fit in a single gang electrical box. Please go to our website www.legrand.us and you can search Wall Switch Sensors. We do not have an option that is a sensor only. The correct device for your situation will depend on your application and if you want a line voltage or low voltage sensor. Please let us know if we can offer any further assistance.
Best Regards,
