When it comes to modern access control and security, electric strikes play an essential role in making controlled access convenient and secure. Whether used in offices, residential buildings, or other facilities, electric strikes offer a practical way to regulate access while allowing doors to remain locked under standard conditions. But exactly how does an electric strike work? This guide will answer that question in detail, covering how electric strikes function, their various configurations, and the security benefits they provide.

Brief Definition of Electric Strike

An electric strike is a door lock mechanism designed to work with an access control system, allowing doors to be unlocked electronically rather than manually. This enables remote control of entry, often triggered by a card reader, keypad, or push-button. Electric strikes are installed on the door frame and operate by releasing or holding the latch, making them compatible with various types of locksets. They are commonly used in secure buildings, offering convenience, remote access, and added safety. span>

How Does an Electric Strike Work?

Understanding the workings of an electric strike is essential for anyone managing access control and security systems. Electric strikes are a popular locking mechanism that provides secure, controlled access without requiring manual unlocking each time someone needs entry. So, how does an electric strike work exactly?

Electric strikes are designed to be installed in the door frame, replacing a traditional strike plate, which is typically a fixed metal component that the door latch locks into. The electric strike, however, operates on a powered mechanism that actively controls the latch. This way, instead of a mechanical release requiring a manual turn of the handle, the electric strike electronically releases the latch bolt when activated, allowing the door to open without the need for a key or handle turn.

Here’s a deeper look at how this mechanism operates in different stages:

• 1. When the Door is Locked

In the locked position, the electric strike keeps the latch bolt firmly in place. Depending on the configuration, the strike may be unpowered (in a fail-secure setup) or powered (in a fail-safe setup) to hold the door in the locked position. The keeper, a component within the electric strike, holds the latch bolt securely, preventing it from retracting and keeping the door shut. This keeper is the part that moves when the electric strike is activated, allowing or preventing access.

• 2. Triggering Mechanism for Entry

The electric strike operates through a triggering mechanism, which is typically controlled by an access system such as a card reader, keypad, intercom, or push-button. When an authorized user interacts with the access system, a signal is sent to the electric strike to release the latch. In response, the keeper inside the strike moves, either momentarily or for a set period, enabling the door to be opened without the need for a handle turn.

For example, if an electric strike is connected to a card reader, when an authorized user swipes their access card, the reader sends a signal to the electric strike to disengage the keeper and release the latch, allowing the door to swing open.

• 3. Access Control Systems

Electric strikes are frequently integrated with broader access control systems. These systems are used in commercial, institutional, and residential settings to regulate who can access specific doors and areas. By incorporating electric strikes into an access control network, facility managers can remotely manage access, grant or revoke permissions, and monitor entry activity. This integration is ideal for buildings with restricted zones or areas that require controlled entry for safety and security.

Through access control software, the electric strike can be set to work with various credentials, such as ID cards, biometric scans, or mobile-based keys, to streamline the entry process. Some advanced systems even support time-based access restrictions, ensuring that users only have access during approved hours.

• 4. Power and Voltage Requirements

Electric strikes are typically low-voltage devices, operating on 12V or 24V power sources. This low-voltage design minimizes energy use while providing reliable performance. A backup power source may be incorporated, especially in setups where the door needs to remain locked (fail-secure) or unlocked (fail-safe) during a power outage. This low-voltage power source makes electric strikes both efficient and easy to integrate into existing electrical and access control systems.

Can an Electric Strike Be Fail-Safe?

Yes, electric strikes can be fail-safe or fail-secure, depending on the specific security and safety needs of the building. Fail-safe and fail-secure configurations refer to what happens to the lock in the event of a power loss:

• Fail-Safe Electric Strikes: In a fail-safe configuration, the electric strike unlocks during a power outage, allowing the door to be opened freely. This is particularly useful for ensuring safe egress in emergency situations, such as in hospitals or other environments where safe evacuation is a priority.
• Fail-Secure Electric Strikes: In a fail-secure configuration, the electric strike remains locked during a power outage. This setup ensures the door stays secure even if power is lost, which is beneficial for high-security areas like data centers or secure offices.

These configurations allow building managers to choose the appropriate strike type for the specific security requirements of each door.

Conclusion

Electric strikes are a powerful tool in any access control setup, offering reliable security and versatile functionality for a wide range of environments. By choosing the correct fail-safe or fail-secure configuration, building managers can ensure that their doors operate optimally to provide security while enabling efficient and safe access. Electric strikes continue to be a valuable asset in modern buildings due to their adaptability, ease of use, and security benefits.

Frequently Asked Questions

What’s the Difference Between Fail-Safe and Fail-Secure Electric Strikes?

The main difference between fail-safe and fail-secure electric strikes is their behavior during a power failure. A fail-safe electric strike unlocks without power, which is essential for easy evacuation. A fail-secure electric strike stays locked when power is lost, providing better security.

Can an Electric Strike Be Used with Any Door Lock?

Yes, electric strikes are compatible with a variety of locks, including cylindrical, mortise, and deadbolt locks. However, it’s important to choose an electric strike model that matches the type of door lock and access control requirements.

Are Electric Strikes Secure?

Yes, electric strikes provide a high level of security, especially when combined with fail-secure configurations. When used in an access control system, they allow controlled entry only for authorized individuals, enhancing both convenience and security.
