Crestron® Passive Infrared Ceiling Mount Occupancy Sensor

At a Glance

Crestron® Passive Infrared Ceiling Mount Occupancy Sensor with walk-through mode and an IR remote

Proposition 65 Warning for California Residents

A low-profile, ceiling-mounted occupancy sensor designed for large areas up to 2,000 square feet. Passive infrared motion sensing affords excellent motion-detection while also providing superior immunity to false triggering. Reliable Cresnet® connectivity allows for direct connection to a Crestron® control system for integrated control of lighting, climate control, and other devices in the room.

The Crestron® GLS-OIR-C-NS sensor features passive infrared (PIR) technology for occupancy detection in a large room or space and delivers a powerful and cost-effective solution for reducing energy consumption and enhancing the functionality of standalone lighting systems. The GLS-OIR-C-NS is a low-profile, ceiling-mounted occupancy sensor designed for areas up to 2,000 square feet, making it great for use in conference rooms, hallways, and private offices. The sensor can connect directly to and be controlled by standalone lighting systems such as the GLPP, GLPAC, or GL-IPAC-SW8. The GLS-SIM Sensor Integration Module provides an interface with a Crestron control system via Cresnet®.

Passive Infrared Occupancy Sensing

PIR sensors utilize a highly sensitive specialized lens to divide the field-of-view into sensor zones.  When a person passes into or out of a zone, the sensor detects the motion and switches the lights on. The lights will remain on for as long as motion is detected in the sensor zones.  PIR sensing achieves dependable motion detection and provides superior immunity to false triggering from vibrations, inanimate objects, or movement in an adjacent corridor. Sensitivity is adjustable for optimal performance.

Walk-Through Mode

This sensor detects momentary occupancy and automatically turns the lights off after 90 seconds with the built-in Walk-Through feature, reducing unnecessary energy consumption.

Versatile Installation

The GLS-OIR-C-NS achieves a discreet, nearly hidden appearance when installed on a typical drywall or droptile ceiling. Hardware is included for fast and simple mounting in a standard 4-inch octagon box or in a hole created with the help of the provided cutout template.

Cresnet Option

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 24 Volts DC power for all of the devices on the Cresnet network. Using the optional GLS-SIM Sensor Integration Module, the GLS-OIR-C-NS becomes a full-featured Cresnet device.

IR Remote

A variety of parameters can be set for the GLS-OIR-C-NS by using the GLS-REMOTE-ODT/OIR remote (sold separately). This IR remote eliminates the need for a ladder when commissioning or setting up any system. The installer can simply stand underneath the sensor and use the remote to complete setup functions and fine-tune the sensor’s settings after installation.
