Which is not a type of electrified lock?

A magnetic strike is not classified as a type of electrified lock because it operates differently than the other options listed. While it is used in conjunction with locking systems and can be part of an access control solution, a magnetic strike is primarily a mechanism that allows a door to be held in the closed position with the aid of an electromagnetic force when the strike is energized. It does not incorporate a locking mechanism by itself, unlike electrified locks that actually secure the door when activated.

In contrast, electric bolts, electromagnetic locks, and electric latches are all designed to actively secure a door in a locked state when power is applied, making them true electrified locks. These types enforce a locking function that is essential for enhanced security in access control systems.
