Light Sensors

GLS-LCL & GLS-LOL

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.

The GLS-LCL is used to monitor and adjust based on the reflected light
levels at a certain location, such as a desk. The GLS-LOL is used to look
at a window and monitor how much light is entering from outside.

GLS-LEXT

The GLS-LEXT is an outdoor light sensor ideal for parking lots,
playgrounds, perimeter lighting, and other outdoor applications. The
sensor is enclosed in a weatherproof housing with a visor for shading and
lens protection. The sensitivity is adjustable with a range of 5-750 foot
candles.

Partition Products

GLS-PART

Surface mount partition sensor easily connects to the GLS-SIM or control processor to manage divisible room environments. When
installed as part of a Green Light system, it allows the control system to divide the lighting controls according to the current room
configuration.

Sensor Interfaces

GLS-SIM

The GLS-SIM is a compact interface device designed to allow Crestron Green Light
sensors to connect directly to a Cresnet control network. The GLS-SIM installs easily at
the sensor location, mounting conveniently inside the electrical box or exposed above
the ceiling. Wiring connections to the network and sensor are facilitated using miniature
screw terminals.

The GLS-SIM is compatible with Crestron GLS-series sensors, as well as with most 24
Volt powered sensors from any manufacturer. Up to 1A at 24 VDC power is available to
support multiple sensors in parallel. The GLS-SIM actually includes two sensing inputs,
each capable of sensing a contact closure, logic level, or 0-10V signal. When used with
a Crestron IPAC or iLux system, setup is simplified using onboard DIP switches to select
the sensor type (i.e. occupancy, photocell, partition, etc.) and operating mode (i.e.
normally-open or normally-closed).
