How Does An Electromagnetic Door Lock Work

That is that the electromagnetic lock immediately unlocks when the premises fire alarm is actuated.

How does an electromagnetic door lock work. Indoor magnetic lock with built in buzzer electromagnetic lock. By an electronic card reader by a keypad or by a wireless remote control sensor. Electronic door locks also involve parts called actuators which connect the bolt or the cylinder to a small motor completely buried within the door or frame itself. Others use a solenoid a metal core surrounded by a single coiled wire.

As they require power to remain locked this allows them to be fail safe making electromagnetic door locks safe for use as emergency exits. Electromagnetic locks use electricity to make metal temporarily magnetic. Locks include two strike plates to control two doors at once. And a magnetic coded lock exactly like the nearly unpickable lock evva mcs is a mixture of a standard lock and a magnetic keyed lock.

A magnetic keyed lock uses variations in the push and pull of a magnetic key to set the pins. Also known as electromagnetic locks they function with the utilization of current flowing through several coils in an electric wire tied around an iron core. Magnetic door locks are a versatile and an affordable access control mechanism for keeping unwanted visitors out of your premises. The locks must be hardwired.

When the electromagnet is energized a current passing through the electromagnet creates a magnetic flux that causes the armature plate to attract to the electromagnet creating a locking action. The unique requirement for a power supply intended for use with an electromagnetic lock is called the fire alarm interface. Typically the electromagnet portion of the lock is attached to the door frame and a mating armature plate is attached to the door. The two components are in contact when the door is closed.

Once users and security staff get used to their convenience magnetic door locks can be easily neglected therefore enduring various malfunctions. When power is interrupted they instantly release. The motor is controlled by an electrical impulse which may be triggered in a number of ways. How does an electromagnetic lock work.

For use alone or as part of an access control system these locks use electromagnetic force to hold double doors closed. 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. Most cases the armature plate is on the edge of the door while the electromagnet is wired to the building s power grid in the wall next to the door frame.
