The LightSync Conditional Occupancy Sensor 8 Input Module (COS8I) allows conditional configurations for each of the 8 inputs, and is designed to power and receive signals from multiple occupancy sensors. Each LightSync input allows for conditional statements related to the occupancy sensor inputs and pilots in the module. ¨AND¨ and ¨OR¨ logic schemes can be configured for each input, allowing users to create overlapping conditionals for multiple occupancy sensor zones within the COS8I module. Each input conditional statement consists of NO/NC closures and LS device pilot status in a 16x16 matrix. The LS device inputs are programmed in the LL panel to control any relay(s), group(s) or preset(s).
