Electric Strike

TL/DR: An electric strike is an access control device that replaces a standard door strike and allows a door to be locked or unlocked electronically, typically in response to a credential, keypad entry, or remote access system.

What is an Electric Strike?

An electric strike is an electromechanical door locking device used in access control systems to control entry and exit. It works in conjunction with a standard lockset and is installed in the door frame. When activated, the strike releases the latch, allowing the door to open without physically turning the handle or using a key.

Electric strikes are commonly used in office buildings, apartment complexes, and secured facilities to integrate with keycard readers, keypads, or remote entry systems.

How Does an Electric Strike Work?

  1. Credential or Input Received – A user presents a keycard, enters a PIN, or is granted remote access.
  2. Signal Sent to Electric Strike – The access control system sends an electrical signal to the strike.
  3. Strike Releases the Latch – The electric strike momentarily moves to allow the door to open without manipulating the lock.
  4. Automatic Relocking – Once the door closes, the electric strike returns to its locked position.

For example, in a secured office, when an employee swipes their keycard, the electric strike momentarily disengages, allowing them to push or pull the door open.

Types of Electric Strikes

  1. Fail-Secure (Power-to-Unlock) – Remains locked during a power outage, requiring electricity to unlock.
  2. Fail-Safe (Power-to-Lock) – Unlocks automatically if power is lost, commonly used in emergency exit scenarios.
  3. Continuous Duty Strikes – Designed for doors that need to remain unlocked for long periods.
  4. Intermittent Duty Strikes – Used for brief unlocking periods when a credential is presented.

How to Implement an Electric Strike in an Access Control System

  1. Choose the Right Type – Select fail-secure or fail-safe based on security and emergency requirements.
  2. Install in the Door Frame – Replace the standard strike plate with the electric strike.
  3. Connect to the Access Control System – Wire the strike to a power source and integrate it with keycard readers, keypads, or remote controls.
  4. Configure Access Rules – Set up authentication methods and entry permissions.
  5. Test & Maintain – Regularly inspect and test the strike to ensure proper operation.

Conclusion

An electric strike enhances security and convenience by allowing electronic control of door locking mechanisms. It is widely used in modern access control systems, providing flexible and efficient entry management while maintaining safety and security standards.
