Crestron’s surface-mounted Green Light Integrated Switching Panel provides internal controls for small commercial installations. The system allows up to eight 16A circuits of switched load at 120V to 277V AC and can be expanded to support up to 64 switched-load circuits by adding external panels and switching modules. A local input for sensors and keypads is included along with an LCD interface for installers and users to configure the system without connecting to a computer. The panel features easy set up and programming for a complete switching system consisting of up to 64 switched loads, 16 local and two remote keypads, 24 occupancy and photo sensors, eight contact enclosures, and 100 time-clock events. Lights can be programmed to turn on and off automatically via a built-in astronomical time clock.
