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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCoordinates the opening sequence of paired doors on LCN automatic operator systems.\u003c\/li\u003e\n\u003cli\u003eEnsures the inactive leaf opens ahead of the active leaf to prevent binding.\u003c\/li\u003e\n\u003cli\u003eCompatible with LCN power operator installations for vestibule and double-door applications.\u003c\/li\u003e\n\u003cli\u003eProvides relay switching for reliable timing and control.\u003c\/li\u003e\n\u003cli\u003eDesigned as a factory-matched accessory for seamless integration with LCN operators.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eFunctional Details\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe 8310-845 relay and sequencer manages the timing between two door leaves so the doors open in the correct order and close without interference.
