This is possible because the electrical current is used to keep the door locked and removing power disengages the locking mechanism.
Magnetic door locks power outage.
Magnetic locks consist of an electromagnet and armature plate.
Use cables that are wider than 0 2 mm.
As they require power to remain locked this allows them to be fail safe making electromagnetic door locks safe for use as emergency exits.
Thinner cables are not sufficient to carry power all the way from the power source to the door lock.
Fail secure locks attracts the armature plate leaving the door magnetically locked when power is lost from the device.
The built in feature of unlocking in the result of a power outage referred to as fail safe was the founding idea of the electromagnet.
Exiting while there is a power outage is still possible via the panic bar which is inside the building.
Magnetic door locks require a constantly available source of power.
Apply battery backup power supply to individual door locks to solve power outages and enable 24 7 electricity supply.
Shear locks combine the power of an electromagnet with the strength of a mechanical interlock to produce a locking solution which can be used on bi swinging doors.
Magnetic locks come in a few different forms.
As a result the magnetic door locks for home will not be fail secure that is in the event of a power outage the door will be unlocked.

Disrupting the current flowing through the metal makes it lose magnetism.
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.
Do not rest on a lock that is difficult to pick or door that locks.
Fail safe locks releases the armature plate and de energizes leaving free access when power is lost from the device.
Locking devices can be either fail safe or fail secure.
The panic bar will still activate the lock so that the door will release.
There are two main types of electric locking devices.
This ensures safety is first priority.
An electromagnetic lock magnetic lock or maglock is a locking device that consists of an electromagnet and an armature plate.
Protects workers in times of emergency.
Measure the voltage at the lock point when the lock is in operation mode.
Any binding between the door the door lock and the strike will cause problems.
The electrified portion of the lock is mounted on the door frame and the armature is mounted on the door.
Which means that in the result of an emergency or power outage the doors will unlock.
Fail secure locks ensure security is first priority.
Magnetic door lock image from wikipedia magnetic door locks are good for local low risk security applications such as indoor closets where occupants are stationed in the vicinity or they fall within the perimeter of a more tightly secured area.
