What is an Electric Strike Lock?
An electric strike lock is a vital component in access control systems. It is typically installed on the door frame and works in tandem with a lockset or latch on the door itself.
Physical Structure: Structurally, it consists of a metal housing that contains the internal mechanism. The housing is usually made of durable materials such as stainless steel or high - grade aluminum alloy to withstand the forces exerted during normal door use and potential security threats. Inside the housing, there is a solenoid, which is an electromagnet, and a latch - retracting mechanism.
Function in Access Control: Electric strike locks play a crucial role in modern security setups. They are used in a wide range of applications including commercial buildings (such as offices, hotels, and retail stores), educational institutions, and industrial facilities. They provide a means of electronically controlling access to a building or a specific area within a building. For example, in an office building, employees can use access cards, key fobs, or enter PINs to gain entry through doors equipped with electric strike locks.
How Does an Electric Strike Lock Work?
Authorization Signal Reception: When a user attempts to gain access, the access control system (such as a card reader, biometric scanner, or keypad) validates the user's credentials. If the credentials are correct, the access control system sends an electrical signal to the electric strike lock. This signal is usually in the form of a low - voltage direct current (DC), typically ranging from 12V to 24V, depending on the specific model of the lock.
Solenoid Activation: The electrical signal activates the solenoid inside the electric strike lock. When the solenoid is energized, it creates a magnetic field that causes a plunger or latch - retracting mechanism to move. This movement disengages the latch or bolt of the door from the strike plate, allowing the door to be opened.
Door Opening and Closing: Once the latch is retracted, the door can be pushed or pulled open. After the user passes through the door and closes it, the electric strike lock resets. In some cases, the reset may occur automatically when the door closes due to the mechanical design of the lock and the interaction with the door latch. In other cases, a separate signal from the access control system may be required to re - engage the latch and secure the door.
Fail - Safe and Fail - Secure Modes: Electric strike locks can operate in two main modes: fail - safe and fail - secure. In a fail - safe mode, if there is a power outage or a disruption in the electrical signal, the lock will automatically disengage, allowing the door to be opened. This is useful in emergency situations such as a fire, ensuring that people can evacuate easily. In a fail - secure mode, a loss of power or signal causes the lock to remain engaged, keeping the door locked. This mode is preferred in high - security applications where it's essential to prevent unauthorized access even in the event of a power failure.
