The GLS-SIM is a compact interface device designed to allow Crestron Green Light® sensors to be connected directly to a Cresnet control network. Cresnet® is the communications backbone for Crestron sensors, dimmers, keypads, touch panels, shade controllers, thermostats, and many other devices. This flexible 4-wire bus provides data communications and 24 Volts DC power for all of the devices on the Cresnet 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 @ 24VDC 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 analog 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).
