It connects to a Crestron control system via Cresnet for centralized occupancy-based lighting automation and daylight harvesting in commercial spaces.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eThe GLS-ODT-C-CN combines PIR motion detection for gross occupancy with 40 kHz ultrasonic sensing for fine-motion detection, reducing false vacancies in offices, conference rooms, and open-plan spaces. The built-in photosensor measures ambient light from 0 to 1,000 lux and feeds that data to the Crestron system for daylight harvesting and load-shedding applications. Coverage is 360° over 2,000 sq ft from a ceiling mount. The sensor draws 1.5 W (60 mA at 24 VDC) from the Cresnet bus and connects via a 5-pin terminal block with an additional EXT pin for an external photosensor input. Sensitivity, timeout, PIR\/ultrasonic zones, and LED indicators are all configurable via an IR remote (sold separately).
