Sensors
Adding sensors makes a smart system even smarter. Sensors save on energy costs while enhancing functionality
and reliability.
The Sensor Advantage
• Reduced energy usage
• More consistent lighting levels
• Completely automatic
Automated Actions
A system with sensors will automatically control lights based on occupancy. When no one is in a room, lights shut
off and energy is conserved. Sensors also help with light harvesting by monitoring ambient light. A system with
sensors can ramp the artificial lighting up or down depending on the amount of natural light entering a room. This
allows consistent lighting conditions while maximizing energy savings. Since everything is automatic, human error
is eliminated.
Occupancy Products
GLS-ODT and GLS-OIR
Crestron Green Light sensors deliver a powerful 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.
