Locking devices can be either fail safe or fail secure.
How do electromagnetic locks for doors work.
Magnetic locks are keyless and its locking effect is controlled by the solenoid or the electromagnetic strip.
An electromagnetic lock creates a magnetic field when energized or powered up causing an electromagnet and armature plate to become attracted to each other strongly enough to keep a door from opening.
Fail safe locking devices are unlocked when de energized.
As they require power to remain locked this allows them to be fail safe making electromagnetic door locks safe for use as emergency exits.
Typically the electromagnet portion of the lock is attached to the door fram.
Direct pull electromagnetic locks are inherently fail safe.
This is achieved by the armature plate attached to the door.
Most cases the armature plate is on the edge of the door while the electromagnet is wired to the.
This means of course that maglocks require power to lock.
A fail secure locking device remains locked when power is lost.
When a magnet connected to a door s frame gets energized by current flowing through the coils the door is locked.
There are two main types of electric locking devices.
An electromagnetic lock magnetic lock or maglock is a locking device that consists of an electromagnet and an armature plate.
The magnet itself is designed with an electrical coil which when powered creates a strong electro magnetic field which is how maglocks can offer such impressive holding forces.
A mag lock is a type of automatic lock which simply takes advantage of this controllable magnetic property.
Electromagnetic lock work an electromagnetic lock creates a magnetic field when energized causing an electromagnet and armature plate to become attracted to each other strongly enough to keep a door from opening according to hangseng magnetech inc.
When the electromagnet is energized the armature plate is attracted to it.
