How Does The Magnetic Door Lock Work

Fail safe locking devices are unlocked when de energized.

How does the magnetic door lock work.

When a magnet connected to a door s frame gets energized by current flowing through the coils the door is locked. When the lock is triggered power is cut and the door unlocks. When power is applied to the door lock or door holder the electromagnet is turned on and keeps the door locked or the door held open. Depending on the lock chosen depends on the voltage and strength of the electromagnetic force.

A fail secure locking device remains locked when power is lost. The magnetic field is so strong that the force secures door and keeps it from being opened. When an electrical current is passed through the electromagnet the door is effectively locked. Maglocks operate on a fail safe mechanism.

When the electromagnet is energized the armature plate is attracted to it. Introduced in 1989 the magnetic lock features an electromagnet set into the door frame and what is called an armature plate set into the door. In addition employees won t have to worry about locking the door behind them as the magnetic lock system will do that automatically. A mag lock is a type of automatic lock which simply takes advantage of this controllable magnetic property.

Typically the electromagnet portion of the lock is attached to the door fram. There are two main types of electric locking devices. Once the lock on the door has received this signal from the card reader it can then be opened using the door s lockset or push bar as it would normally be. This is achieved by the armature plate attached to the door.

An electromagnetic lock magnetic lock or maglock is a locking device that consists of an electromagnet and an armature plate. It is when the current is disrupted that access may be gained. Mag locks such as the deedlock mag locks are made up of an electromagnet and an armature plate. This means that when power is supplied to the lock the magnet is activated and the two halves one screwed onto the wall and one onto the door are stuck together keeping the door locked.

The magnetic field is strong enough to prevent the door from being forced open requiring a user to input a security code or present a badge to deactivate the electromagnet and free the door. Once a fire alarm occurs the fire alarm panel sends a signal to the control relay to activate. When current flows through the electromagnet it creates a strong magnetic field attracting the relatively large surface of the armature plate on the door. Magnetic door locks and magnetic door holders work the same way.

The plate is attached to the door and the magnetic to the door frame. Magnetic locks are keyless and its locking effect is controlled by the solenoid or the electromagnetic strip.
