What is the primary function of an electric strike?

1. To retract the bolt when a valid key is used

2. To allow for electronic access without a key

3. To replace a standard door strike and facilitate latching

4. To lock doors automatically at a certain time

The correct answer is: To replace a standard door strike and facilitate latching

The primary function of an electric strike is to allow for electronic access without a key. An electric strike is a component of an access control system that replaces a standard door strike and provides a means for doors to be unlocked electronically, often through a card reader, keypad, or other access control device. When a valid access credential is presented, the electric strike unlocks, allowing the door to open. This functionality is essential for modern entry systems in both commercial and residential applications, as it enhances security while offering convenience. Utilizing an electric strike allows for seamless integration into a building's overall security system, enabling controlled access to shared spaces or restricted areas without the need for traditional keys. While retraction of the bolt can happen when electronic access is granted, that is more of a byproduct of its electronic access capabilities rather than the primary function. Similarly, while some electric strikes can facilitate latching, their main purpose revolves around granting access without using a physical key. Locking doors automatically at a certain time relates more to timed access control systems and is not the core purpose of an electric strike.
