In a fail-safe electrified mortise lock, which condition is necessary for the lock to remain locked?

In a fail-safe electrified mortise lock, the mechanism is designed to remain locked when power is applied. This type of lock is engineered to unlock during a power failure, ensuring safety by allowing free exit from a secured area, which is particularly important in emergency situations. Therefore, for the lock to remain in a locked state, continuous power supply is crucial. When power is provided, the lock’s electromagnetic components hold the locking mechanism in place, preventing unauthorized access.

If power is interrupted or removed, the lock defaults to an unlocked state, facilitating egress and enhancing life safety. This makes it vital for businesses or facilities focusing on safety protocols to understand that consistent power is necessary for the operational security of this type of lock.
