Provides a vacancy sensor for Zum™ commercial room lighting systems. Reduces wasteful energy usage by turning off room lighting when the room is vacant.

A Zum™ vacancy sensor offers a cost-saving solution for reducing energy usage in rooms equipped with a Zum commercial room lighting system. The ZUMMESH-PIR-VACANCY-BATT is a passive infrared vacancy sensor designed for ceiling mount installation in areas up to 500 square feet or 46.5 square meters. It communicates wirelessly with a Zum dimmer, switch, or load controller to turn lights off automatically when the room is vacant. Up to eight vacancy sensors may be employed for increased coverage.

The ZUMMESH-PIR-VACANCY-BATT is battery powered and completely wireless. It operates for up to ten years or more on a single 9 Volt lithium battery (included). Zum Mesh wireless technology affords easy pair and play setup and integration as part of a complete Zum commercial room lighting system.

Featuring passive infrared (PIR) technology, the ZUMMESH-PIR-VACANCY-BATT employs a highly sensitive specialized lens that divides the field-of-view into sensor zones. The sensor detects motion when a warm body passes between zones, achieving dependable motion detection with superior immunity to false triggering from vibrations, inanimate objects, or movement in an adjacent corridor. The detection sensitivity is adjustable for optimum performance. Timeout can be set anywhere from 30 seconds to 30 minutes to maintain occupied status during short periods of inactivity. A half mask and perforated mask are included to customize the coverage area.

The ZUMMESH-PIR-VACANCY-BATT includes grace occupancy, so if the lights turn off while someone is in the room, they can be turned back on by simply waving a hand within the 15 second grace period.
