{"product_id":"crestron-gls-oir-c-ns","title":"Crestron GLS-OIR-C-NS – Passive Infrared Ceiling Mount Occupancy Sensor","description":"\u003ch2\u003eProduct Overview\u003c\/h2\u003e\u003cp\u003eThe Crestron GLS-OIR-C-NS is a passive infrared (PIR) ceiling-mount occupancy sensor designed for use with Crestron lighting control and building automation systems. It detects the presence or absence of occupants in a space by sensing infrared (heat) movement and reports that status to the control system to automate lighting, HVAC, or other building functions. The NS designation indicates no shroud is included.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eOccupancy-based automation is a standard energy management strategy in commercial buildings, and the GLS-OIR-C-NS provides reliable PIR detection from a ceiling-mounted position. Ceiling mount placement maximizes coverage area and provides a clear overhead sightline across a room, reducing blind spots common with wall-mounted sensors. The sensor connects to Crestron control processors and lighting systems via standard Cresnet or compatible wiring, making it straightforward to integrate into new or retrofit installations. Without a shroud, the sensor delivers its full field of view, which is appropriate when maximum coverage is required without intentional restriction of the detection zone.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePassive infrared detection technology for reliable occupancy and vacancy sensing\u003c\/li\u003e\n\u003cli\u003eCeiling-mount installation maximizes coverage and reduces detection blind spots\u003c\/li\u003e\n\u003cli\u003eNo-shroud (NS) design provides full, unrestricted field of view\u003c\/li\u003e\n\u003cli\u003eIntegrates with Crestron lighting control and building automation processors\u003c\/li\u003e\n\u003cli\u003eSuitable for new construction and retrofit installations\u003c\/li\u003e\n\u003cli\u003eSupports automated lighting, HVAC, and energy management workflows\u003c\/li\u003e\n\u003cli\u003eLow-profile ceiling mount for unobtrusive installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTypical Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCommercial office spaces with occupancy-based lighting control\u003c\/li\u003e\n\u003cli\u003eConference rooms requiring automatic lights-on\/off based on occupancy\u003c\/li\u003e\n\u003cli\u003eClassrooms and educational facilities with energy management systems\u003c\/li\u003e\n\u003cli\u003eHospitality spaces automating HVAC and lighting based on room occupancy\u003c\/li\u003e\n\u003cli\u003eRetail environments integrating occupancy data into building management\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eAttribute\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003eGLS-OIR-C-NS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDetection Technology\u003c\/td\u003e\n\u003ctd\u003ePassive Infrared (PIR)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Type\u003c\/td\u003e\n\u003ctd\u003eCeiling mount\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShroud\u003c\/td\u003e\n\u003ctd\u003eNone (NS – no shroud)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Systems\u003c\/td\u003e\n\u003ctd\u003eCrestron lighting control and building automation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eOccupancy and vacancy sensing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eFAQs\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eQ: What is the detection range of the GLS-OIR-C-NS?\u003c\/strong\u003e\u003cbr\u003eA: Detection range depends on ceiling height and the sensor's field of view specifications. Refer to the Crestron GLS-OIR-C-NS product datasheet for coverage area details at standard ceiling heights.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: Can this sensor be used for vacancy-only (manual-on) control?\u003c\/strong\u003e\u003cbr\u003eA: Yes. When integrated with a compatible Crestron lighting control processor, the sensor can be configured for vacancy-only operation where lights must be turned on manually but turn off automatically when the space is vacant.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: Does the no-shroud configuration affect detection accuracy?\u003c\/strong\u003e\u003cbr\u003eA: Without a shroud, the sensor operates at its full designed field of view. A shroud is used when you need to restrict the detection zone—for example, to prevent sensing in adjacent areas. For full-room coverage, the no-shroud configuration is appropriate.\u003c\/p\u003e","brand":"Crestron","offers":[{"title":"Default Title","offer_id":47759586197740,"sku":"GLS-OIR-C-NS","price":220.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/7982\/4364\/files\/master_photo_a-gls-oir-c-ns.png?v=1781800040","url":"https:\/\/creationnetworks.net\/products\/crestron-gls-oir-c-ns","provider":"Creation Networks","version":"1.0","type":"link"}
