{"product_id":"crestron-gls-oirlcl-c-cn","title":"Crestron GLS-OIRLCL-C-CN – Miniature Ceiling PIR \u0026 Daylight Sensor, Cresnet","description":"\u003ch2\u003eProduct Overview\u003c\/h2\u003e\u003cp\u003eThe Crestron GLS-OIRLCL-C-CN is a miniature flush-ceiling passive infrared (PIR) occupancy sensor with closed-loop daylight sensing. It communicates via Cresnet wired bus and installs through a 1-inch diameter ceiling hole, projecting only 0.2 in. (5 mm) from the surface for a near-invisible installation profile.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eCombining 64-zone PIR motion detection with a 0–1,000 lux closed-loop photocell, the GLS-OIRLCL-C-CN provides both occupancy detection and daylight harvesting feedback to a Crestron control system via Cresnet. Coverage area is 450 sq ft in a rectangular pattern (18.57 × 24.34 ft at 8.2 ft ceiling height), with a maximum ceiling height of 16.4 ft. Vacancy mode and walk-through mode are both supported. Configuration is handled via Crestron Toolbox software or an optional IR remote. The IP64-rated housing withstands light moisture and dust, making it suitable for a wider range of ceiling environments. It is also compatible with XiO Cloud for remote provisioning. Drawing 1 W (42 mA at 24 VDC) from the Cresnet bus, it requires no separate power supply.

The GLS-ODT-C-CN combines PIR and ultrasonic dual-technology sensing for better fine-motion detection in a larger 4.8-inch diameter surface-mount form factor. The GLS-OIRLCL is preferred where minimal ceiling penetration and daylight harvesting are priorities; the GLS-ODT-C is preferred where reliable minor-motion detection (seated occupants) is critical.\u003c\/dd\u003e\n\u003cdt\u003eDoes this sensor require a separate power supply?\u003c\/dt\u003e\n\u003cdd\u003eNo. It draws 1 W (42 mA) from the Cresnet bus. No additional power wiring is needed beyond the Cresnet cable run to the ceiling location.\u003c\/dd\u003e\n\u003cdt\u003eWhat is walk-through mode?\u003c\/dt\u003e\n\u003cdd\u003eIn walk-through mode, if a space is occupied for 90 seconds or less, lights turn off 60 seconds after vacancy. This prevents lights from remaining on after a brief transient occupancy such as someone walking through without staying.\u003c\/dd\u003e\n\u003c\/dl\u003e","brand":"Crestron","offers":[{"title":"Default Title","offer_id":47759586263276,"sku":"GLS-OIRLCL-C-CN","price":290.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/7982\/4364\/files\/master_photo_A-GLS-OIRLCL-C-CN.png?v=1781800053","url":"https:\/\/creationnetworks.net\/products\/crestron-gls-oirlcl-c-cn","provider":"Creation Networks","version":"1.0","type":"link"}
