Which choice is not a category of electrified lock?

The choice that is not a category of electrified lock is correctly identified. An electrified latch, while it may sound plausible, is not commonly recognized or categorized as a distinct type of electrified lock.

Electromagnetic locks and electric strikes are widely accepted categories in the world of electronic access control. An electromagnetic lock typically uses an electromagnet to secure a door, while an electric strike allows for remote release of the lock, enabling access without a physical key. The electrified deadbolt is also a well-known type of locking mechanism that incorporates electrical components to enhance security.

In summary, the absence of an "electrified latch" from established categories highlights the importance of understanding standard terminology in electronic locking systems. This understanding is crucial for anyone working in the field of electronic access control.
