Occupancy Sensor for 1000 sq ft

This ceiling-mounted sensor uses ultrasonic technology to detect motion across 1000 sq ft of space. It operates on a 24V DC hard-wired connection and provides both motion sensing and dimming control. The unit is designed for office environments and finishes in Office White.

Adaptive Time Delay from 8 to 40 min

The sensor adjusts its shut-off delay automatically between 8 and 40 minutes based on observed traffic patterns. A manual override is also available for fixed timing requirements. This adaptive behaviour reduces unnecessary lighting runtime without user intervention.

24V DC Hard-Wired Power Requirement

The device requires a 24V DC hard-wired supply and does not operate on mains voltage directly. Installers must provide a compatible low-voltage circuit. Without this specific power source the sensor will not function.

Questions about this item

How often will the adaptive time delay need recalibration after installation?

The adaptive delay self-adjusts between 8 and 40 minutes based on occupancy patterns, so no periodic recalibration is required.

At 1,000 sq ft coverage, what is the first limitation during continuous occupancy?

The 24 V DC supply current becomes the limiting factor before the ultrasonic sensing range is reached.

Does the sensor generate audible noise or noticeable heat when powered 24 V all day?

Ultrasonic operation is silent and the low-voltage circuit produces negligible heat during continuous use.
