Occupancy and Photocell Sensors
GLS-ODT & GLS-OIR
Green Light Occupancy Sensors
Crestron Green Light™ sensors deliver a powerful and
cost-effective solution for reducing energy costs and
enhancing the functionality of lighting and environmental
systems. Crestron offers ceiling and wall mount occupancy
sensors for areas up to 2500 square feet.
Advanced self-adaptive motion sensing using a combination
of ultrasonic and passive infrared technologies affords
extreme reliability for control of lighting, climate control and
other devices in the room. A built-in photocell can be set to
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.
Sensors are easily connected to the lighting control processor
via the Cresnet control network using a GLS-SIM Sensor
Integration Module. Alternately, they may be connected
directly via a digital input port. Please refer to the product
specification sheet for complete information.

Green Light Photocell Light Sensors
Crestron Photocell Light Sensors are designed for daylight
harvesting applications to control the balance of natural and
artificial lighting in an indoor space. By harnessing natural
daylight from windows and skylights, electrical lighting can
be turned off or dimmed, reducing energy usage while
maintaining a consistent light level for a more efficient and
comfortable work space. Outdoor lighting may also be turn
off and on automatically using a photocell light sensor.
Please refer to the product specification sheet for complete
information.
