How Do Magnetic Door Locks Work

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.

How do magnetic door locks work.

Magnetic door locks and magnetic door holders work the same way. When a magnet connected to a door s frame gets energized by current flowing through the coils the door is locked. Fail safe locking devices are unlocked when de energized. There are two main types of electric locking devices.

Not unlike what you learn about magnetics magnetic locks work by north and south end meeting and sealing but magnetic door locks use an electrical current to produce a stronger magnetic force. A magnetic keyed lock uses variations in the push and pull of a magnetic key to set the pins. Magnetic locks are keyless and its locking effect is controlled by the solenoid or the electromagnetic strip. 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.

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. What makes it work a magnet has a strong magnetic field that attracts its opposite. 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. They are either attracted to each other or repel away from one another.

The plate is attached to the door and the magnetic to the door frame. Typically the electromagnet portion of the lock is attached to the door fram. By understanding exactly how these magnetic locks and card access control systems really work you can begin to get an idea of just how important they can be for your business. Locking devices can be either fail safe or fail secure.

The cards or fobs trigger magnets inside the magnetic lock in one of three ways. Every magnet has two poles north and south. A fail secure locking device remains locked when power is lost. Through a magnetic carving embedded in the card or fob with a coded magnetic stripe that is swiped into the card reader radio frequency identification rfid technology that transmits a frequency signal to the card reader via a smart chip.

Installation of a magnetic lock electromagnetic locks are designed to be installed at the top of the door and door frame. This is achieved by the armature plate attached to the door. Direct pull electromagnetic locks are inherently fail safe. Simply put card access control replaces traditional keys and instead uses a key card and magnetic locking system to allow individuals to gain access into a building.

If you put two magnets together you ll discover two things. This is the best location to wire the magnet to the building s electrical circuit and ensure that nothing inhibits the door from opening and closing normally when it s unlocked. Once a fire alarm occurs the fire alarm panel sends a signal to the control relay to activate. Mag locks such as the deedlock mag locks are made up of an electromagnet and an armature plate.
