        GLS-LEXT

        Crestron Green Light® Photosensor, Outdoor

        • Wall-mount photosensor
        • Measures the outdoor light levels
        • Weatherproof with visor for protecting the lens

        The GLS-LEXT is a photosensor for use in outdoor spaces such as in parking lots, playgrounds, and storage areas. The sensor measures daylight and signals the control system to turn on the exterior lights when the light level falls below a certain threshold. Unlike with a timer, a sensor can account for daytime storms and doesn't need to be programmed for sunset and sunrise.

        The GLS-LEXT continually monitors the total ambient light level and can adjust the lighting as necessary to reach the desired light level. The sensor’s sensitivity is adjustable so that a 10 Volt signal matches full daylight and a 0 Volt signal matches total darkness. A built-in visor provides more consistent readings by blocking direct sunlight and also protects the lens from the elements.

        The GLS-LEXT has a simple three-wire interface that allows for direct connection to a Crestron® control system via a single Versiport I/O or analog input port. The sensor can use 24 Volts of power straight from the Cresnet® control bus.[1]

        Using the optional GLS-SIM Sensor Integration Module, the GLS-LEXT becomes a full-featured Cresnet device, streamlining the total lighting system. Cresnet provides a simple solution for configuring and wiring sensors as part of any complete Crestron system. The Cresnet bus is the communications backbone for many Crestron keypads, lighting controllers, shade motors, sensors, and other devices. Cresnet is a simple, yet flexible 4-wire network that provides bidirectional communication and 24VDC power for Cresnet devices.
