Crestron® occupancy sensors and daylight sensors offer a powerful, cost-saving solution for reducing energy consumption and enhancing system functionality. As part of a complete Crestron system, they can be used to enable automation of lighting, shading, HVAC, and AV equipment in a conference room, classroom, office, hallway, or other space. Using Crestron sensors, room lighting can automatically turn on when the room is occupied, turn off when it is vacant, and dim to a lower level when there is sufficient natural daylight from windows and skylights. Sensors can also be used to enhance the capabilities of a room scheduling, asset management, or energy monitoring solution through integration with the Crestron XiO Cloud™ service
The GLS-OIRLCL-C-CN serves dual functions as a passive infrared occupancy sensor and closed-loop photocell daylight sensor (photosensor). It can also operate in vacancy-only mode, and is designed to cover an area up to 450 sq ft (42 sq m). Miniaturized construction affords a nearly hidden appearance when installed in a drywall or drop-tile ceiling. It communicates with a Crestron control system via the Cresnet® network. Setup and configuration is accomplished using Crestron Toolbox™ software or the optional IR remote (GLS-REMOTE-ODT/OIR, sold separately).
Passive Infrared Occupancy Sensing
Passive infrared (PIR) technology employs a highly sensitive, specialized lens that divides the field-of-view into sensor zones. The sensor detects motion when a person 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 from 30 seconds to 30 minutes to maintain occupied status during short periods of inactivity.
Walk-through mode turns off the lights quickly when a room is occupied for a short period of time. When Walk-through mode is enabled and a room is occupied for 90 seconds or less, the lights will turn off 60 seconds after the room is vacated.
When the lights turn off in a room programmed to vacancy only mode, a 15 second grace period starts during which the room lights can be turned on again by simply waving a hand to trigger the sensor.
A built-in photosensor detects the amount of ambient light in the room. This allows daylight harvesting to be performed which can dim or keep the lights off when there is sufficient daylight in the room.
Ceiling Flush Mount Installation
The GLS-OIRLCL-C-CN achieves a discreet, nearly hidden appearance when installed on a typical drywall or drop tile ceiling. The GLS-OIRLCL-C-CN is designed to install in a 1 in. (25 mm) diameter hole and is held in place by the integrated compression clips.
Use with the MMK‑RS (sold separately) to simplify the wiring and sensor positioning during the rough-in stage of construction. The MMK-RS has an option to completely flush mount the sensor and make it virtually hidden on a wall.
Room Usage Monitoring
The GLS-OIRLCL-C-CN is compatible with the Crestron XiO Cloud™ service, which is an IoT (Internet of Things) based platform for remotely provisioning, monitoring, and managing Crestron devices across an enterprise or an entire client base. Built on the Microsoft® Azure® software platform and utilizing Microsoft's industry leading Azure IoT Hub technology, Crestron XiO Cloud enables installers and IT managers to deploy and manage thousands of devices in the time it previously took to manage just one. Unlike other virtual machine based cloud solutions, Azure services provide unlimited scalability to suit the ever growing needs of an enterprise.

Cresnet® Wired Communication
The GLS-OIRLCL-C-CN uses the dependable Cresnet wired network for communication between devices. Cresnet provides a simple solution for configuring and wiring keypads and sensors as part of any complete Crestron system. Cresnet is the communications backbone for Crestron lighting dimmers, keypads, shades, thermostats, and many other devices. This flexible 4-wire bus provides data communications and 24VDC power for all of the devices on the Cresnet network.
