Door Interlocking System

door interlock controller achieve this by preventing simultaneous access of door /room by ensuring that when one door for a room is open then other door is closed. Push buttons are available for door access. Emergency stations are available for opening for all doors. Delay between each door openings to maintain required pressure.
