How does a door interlocking system work?

Door Interlocking Feb 23, 2026
Answer:
A door interlocking system uses electronic controls to coordinate the operation of multiple doors. The system includes sensors, controllers, and locking mechanisms installed on each door. When a person approaches a door, they must first gain access by presenting a valid credential, such as a card, key fob, or biometric scan. Once authorized, the system unlocks that specific door and simultaneously locks any other doors in the interlock sequence, preventing access to other areas.
