The LightSync Input Module is designed to accept up to 4 hardwired switch inputs. Each input accepts a 2 or 3 wire dry contact switch closure or an equivalent open collect signal from any source. Each input module can also be configured to accept a 12-24 VDC signal from security or BAS systems. Any input can be programmed to control any relay(s), group(s), or preset(s) in any or all panels. Each input has an associated pilot status LED output that indicates of the true status of any relay, group, or preset. It may also be programmed to a reverse status (LED is ON if the relay is OFF) or ON always. Inputs have a time-of-day or open/close time of action which allow it to disable the input or change the input type.
