Crestron® Green Light® Passive Infrared Wall Mount Occupancy Sensor with self-adaptive adjustment and ambient light recognition

Proposition 65 Warning for California Residents

Crestron Green Light® sensors deliver a powerful and cost-effective solution for reducing energy costs and enhancing the functionality of lighting and environmental systems. The GLS-OIR-W-2500 is a wall or ceiling mount occupancy sensor designed for large areas up to 2500 square feet to detect when the room is occupied. Advanced self-adaptive, passive infrared motion sensing affords excellent reliability for control of lighting, climate control and other devices in the room.

Passive Infrared Occupancy Sensing

Passive infrared technology achieves dependable motion detection with superior immunity to false triggering from air currents, inanimate objects, or movement in an adjacent corridor. Sensitivity is adjustable for optimum performance.

Self-Adaptive Adjustment

Under the control of its internal microprocessor, the GLS-OIR-W-2500 continually analyzes occupancy behavior and environmental conditions in the room, adjusting itself for optimal functionality so lights turn on and stay on while the room is occupied, and remain off when no one is present. Sensor sensitivity and delayed-off time adjustments are optimized automatically based on day-to-day use of the room to prevent false-on and off conditions. A walk-thru mode provides specialized behavior in instances of brief occupancy, turning lights off quickly when a person enters and exits the room within a period of 2.5 minutes.

Ambient Light Recognition

A built-in photocell is included for detection of natural daylight in the room. When enabled, the photocell can override the occupancy sensor if the ambient light level is above a set threshold, preventing lights from turning on when there is sufficient daylight in the room.

Versatile Installation

The GLS-OIR-W-2500 is ideally designed to afford versatile positioning in any room with low-hanging ceiling fixtures or other obstructions. The twist-and-lock bracket facilitates fast and simple mounting to a drywall or drop-tile surface, or to a standard 4-inch octagon box. Its simple 3-wire interface allows for direct connection to a Crestron control system via a single Versiport I/O input port, with 24 Volt power taken from the Cresnet control bus.

Cresnet® Option

Cresnet provides a simpler solution for configuring and wiring sensors as part of any complete Crestron system. Cresnet is the communications backbone for Crestron lighting dimmers, keypads, touchpanels, shade controllers, 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-W-2500 becomes a full-featured Cresnet device, streamlining the total lighting system. Additional features enable quick and easy setup for use with a Crestron IPAC or iLux® system.

Emerge Alliance Registered

This device is EMerge Alliance® registered and designed to work within a 24VDC room-level power distribution system. The EMerge Alliance is a not-for-profit open industry association leading the rapid adoption of safe DC power distribution in commercial buildings through the development of Emerge Alliance standards[3]. Crestron is a proud member and supporter of the Alliance.
