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 Fusion® Enterprise Management 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 square feet or 42 square meters. 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 (model 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 64 detection 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 can be set to one of three levels for optimum performance. Timeout can be set to one of six settings ranging from 30 seconds to 30 minutes, preventing the sensor from turning off lights or reporting vacancy during moments when the room is occupied but no one is moving. In addition, a “walk-through” mode (Short Timeout) can be enabled to temporarily override the Timeout setting on occasions when the room is only occupied briefly for 90 seconds or less.
