The LCN 8310-845 Relay and Door Sequencer is a control accessory designed for use with LCN automatic door operators, most commonly in paired or vestibule door applications. Its primary role is to coordinate the opening sequence of two doors, ensuring the inactive leaf opens before the active leaf on double-door setups. This sequencing prevents doors from binding and allows astragal-equipped pairs to operate smoothly and reliably. Built to integrate directly with LCN operator systems, the 8310-845 delivers dependable relay switching and timing control for commercial entrances where proper coordination between door leaves is essential for safe, efficient traffic flow.
