What is an Electronic Door Lock?

Electronic LockAn electronic lock, sometimes known as an electric lock, is a class of locking devices that operate by means of an electric current. Some electric locks are stand-alone installations with their own electronic control assembly mounted to the lock. Electric locks have a number of advantages.

The Power of Magnets

According to Kwikset, the electronic door locks use magnets, solenoids or customized motors to actuate the lock by deciding to either supply or remove power. Some electronic locks are activated by switch, such as a door release. Other, more complex electronic door locks rely on biometric examination for access control.

Primary electronic door locks operate via a strong magnetic lock. First, a powerful electromagnet is securely mounted on the door frame while a corresponding armature is secured to the door. By powering up the magnet, the door is held closed via the armature’s resistance. Because of the inherent strong properties in magnetic flow, electronic door locks as particularly attack resistant.

Special Requirements

Electronic magnet locks are not recommended for emergency doors due to fire safety hazards. Certain restrictions in the NFPA 101 and the Americans with Disability Act stipulate mandated access to “simple movement” and “free egress”, which is interpreted as meaning that all persons have the right to open a public door with one motion. Electronic locks may not be suitable for use with some public doors due to the inherent delay built into their mode of operation.

Access control to electronic locks can be achieved by a number of methods, including biometric input, authorized access codes, identification cards with magnetic strips or other methods. All electronic locks can be wired to either remain locked or unlocked in cases of power failure or other operational errors.
