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 door locks power outage.
A fail safe lock will open on the side of ingress in the event of a power outage or in the event of an emergency alarm being pulled.
Luckily most of these doors have what is referred to as a fail safe.
Apply battery backup power supply to individual door locks to solve power outages and enable 24 7 electricity supply.
There are two main types of electric locking devices.
The panic bar will still activate the lock so that the door will release.
Magnetic door locks require a constantly available source of power.
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.
Disrupting the current flowing through the metal makes it lose magnetism.
An electromagnetic lock magnetic lock or maglock is a locking device that consists of an electromagnet and an armature plate.
Which means that in the result of an emergency or power outage the doors will unlock.
Any binding between the door the door lock and the strike will cause problems.
Use cables that are wider than 0 2 mm.
Fail secure locks ensure security is first priority.
A fail secure locking device remains locked when power is lost.
Magnetic locks consist of an electromagnet and armature plate.
Protects workers in times of emergency.
Fail safe locks releases the armature plate and de energizes leaving free access when power is lost from the device.
Measure the voltage at the lock point when the lock is in operation mode.
Thinner cables are not sufficient to carry power all the way from the power source to the door lock.
The electrified portion of the lock is mounted on the door frame and the armature is mounted on the door.

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.
Magnetic locks come in a few different forms.
As they require power to remain locked this allows them to be fail safe making electromagnetic door locks safe for use as emergency exits.
This is possible because the electrical current is used to keep the door locked and removing power disengages the locking mechanism.
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.
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.
Locking devices can be either fail safe or fail secure.
Fail secure locks attracts the armature plate leaving the door magnetically locked when power is lost from the device.
