What is the function of an "electric strike"?

The function of an electric strike is to allow an electric lock to be retracted with an access control system. An electric strike is a specialized device installed in the door frame that interacts with the locking mechanism of a door. When an access control system, such as a keypad, card reader, or biometric scanner, is activated, it sends a signal to the electric strike. This signal releases the locking mechanism, allowing the door to be opened without requiring a physical key.

This integration is essential in security systems because it provides a seamless way to control access while allowing for easy unlocking in response to authorized users. The electric strike is particularly useful in high-security environments where a mechanical key may not be practical or secure enough.

The other choices, while they may relate to various aspects of access control or security systems, do not specifically define the primary function of an electric strike. For instance, providing a visual indication of door status typically involves sensors or lights that display whether a door is locked or unlocked. Enhancing physical security through additional locks refers more broadly to the use of varied locking mechanisms rather than the function of an electric strike itself. Monitoring visitor entries and exits often involves advanced tracking systems or software, rather than the mechanical function of an electric strike.
