How does an electromagnetic door holder work?
Electromagnetic Door Holders A small metal plate is attached to the door and is positioned to come in direct contact with the electromagnet. When energized, the electromagnet will hold onto the metal plate to hold the door open. Mag hold open devices are connected to the fire alarm system or life safety system.
How do you use electromagnetic locks?
The principle behind an electromagnetic lock is the use of electromagnetism to lock a door when energized. The holding force should be collinear with the load, and the lock and armature plate should be face-to-face to achieve optimal operation.
How strong are electromagnetic door locks?
Strength. The average magnetic lock can withstand up to 1200 pounds of force.
How secure are electromagnetic locks?
Electromagnetic locks are very reliable and are rarely hacked into, due to the force necessary to disengage the magnet.

Does a magnetic lock need a power supply?
Magnetic locks depend on constant power to remain secure. For this reason, they need a reliable power source. Most maglocks require a dedicated, individually fused, 12VDC or 24VAC power supply. The power supply needs to be hardwired into the buildings electrical system, typically 120VAC.
Do magnetic locks work without power?
Magnetic door locks require a constantly available source of power. If power is lost, the magnet will not work. Therefore, entry into the secure area is available to mischief-makers and anyone else. Battery backup is available in power supply boxes, but they have to be checked often and replaced regularly.
How does a cyber lock work?

Both the lock and key record all access events, including access granted and unauthorized access attempts.
What is a magnetic lock?
An electromagnetic lock, magnetic lock, or maglock, is a locking device that consists of an electromagnet and an armature plate. It is a magnet that is created when an electrical current is passed through a solenoid (coiled wire wrapped around a metal core).
How does a magnetic lock work?
The magnetic lock relies upon some of the basic concepts of electromagnetism. Essentially it consists of an electromagnet attracting a conductor with a force large enough to prevent the door from being opened. In a more detailed examination, the device makes use of the fact that a current through one or more loops of wire (known as a solenoid) produces a magnetic field. This works in free space, but if the solenoid is wrapped around a ferromagnetic core such as soft iron the effect of the field is greatly amplified. This is because the internal magnetic domains of the material align with each other to greatly enhance the magnetic flux density.
What is the principle behind maglock?
The principle behind a maglock is the use of electromagnetism to lock a door when energized. The holding force should be collinear with the load, and the lock and armature plate should be face-to-face to achieve optimal operation.

What is an electromagnetic lock?
Electromagnetic locks are fail-safe locking mechanisms that require constant power to remain locked. They are designed to provide basic traffic control up to a medium level of security. The basic electromagnetic lock is normally installed onto the jamb of an out swinging door.
What is the current draw of an electromagnetic lock?
Current draw for most electromagnetic locks is minimal, costing much less than a conventional light bulb to operate. The electromagnet component consists of a metal alloy formed in a specific shape. The goal is to produce as large a magnetic field as possible within a limited sized housing.
What is float lock?
It is normally is “float” mounted onto the door, allowing it to rock into position flush against the face of the magnet. To accommodate this needed movement, lock manufacturers usually include rubber washers to install between the armature and the face of the door.
What happens when power is removed from a magnetic lock?
When power is removed from today's magnetic locks, the magnetic field immediately dissipates and the door is immediately unlocked. Earlier models of magnetic locks have suffered from residual magnetism that caused electromagnets to retain a portion of the magnetic field, building in strength over the years.
What happens when a door is closed?
When the door is closed and the electromagnetic lock is energized, the current flowing through the wire coils produces a magnetic field. This magnetic field attracts the armature plate mounted onto the door. The armature is drawn against the electromagnetic lock with sufficient force to prevent the armature (door) from being opened.
How much power does an electromagnet hold?

Why are mag locks used in door locks?
Because there are no moving parts, little or no maintenance is needed and the lock requires little power to operate. Electromagnetic "mag" locks provide a Fail Safe locking mechanism, which requires power to maintain the holding force. For most applications, they secure a door for the purpose of traffic control.
What is recessed mag lock?
Recessed mag lock applications are generally for sliding doors. The recessed application conventional electromagnetic lock can be installed into the locking leg of the doorframe. The Dynalock 2600 Series 650 lbs. holding force mag lock has a narrow backset to accommodate shallow openings. The recessed mag lock contacts the door only when closed.
What is the greatest holding force for a door?
An electromagnetic lock provides its greatest holding force when the door must pull away from the magnet. For a swing type door, the mag lock is placed adjacent to the lock edge of the door, requiring the door face to be pulled directly away. For a sliding door, the mag lock is placed on the locking leg of the doorframe.
What is delayed egress?
The function of the delayed egress electromagnetic lock is to notify when someone is attempting to exit through a secondary door. Immediately the alarm sounds, notifying employees of an attempted exit. Once activated, the door remains locked for either 15 or 30 seconds depending upon code compliance. After the time delay, the delayed egress mag lock releases and the door can be opened. Delayed egress mag locks are connected to the fire alarm system to automatically unlock in case of a fire.
Why are mag locks plated?
Most electromagnetic locks' ferrous metal surfaces are then plated to protect against corrosion and increase durability. Some mag locks have a separate compartment for the wire connections and circuitry.
Why is it so hard to open a mag lock?
Over time the strength of the magnet increases. This can be felt when there is resistance when trying to open the door when the mag lock is not powered. This can eventually result in the door being difficult to open. Most newer mag locks include a release circuit that eliminates residual magnetism.
Can a shear lock be slid open?
In this condition, the door cannot be slid open. Shear style electromagnetic locks can have a holding force of 600 to more than 2500 pounds. Shear style electromagnetic locks are sold under different names including Camden Shear Lock, SDC Hi/Shear and Securitron Shear Aligning Magnalock (SAM/SAM2).

Can you use an electromagnetic lock on aluminum?
Aluminum storefronts are a common application for electromagnetic locks. Because electromagnetic locks have traditionally been mounted at the top of the door and frame, and because storefront doors are relatively flexible, pulling on a door with an electromagnetic lock often can result in the door warping, perhaps the glass breaking or the electromagnetic lock bond being broken.
Is a shear lock an electromagnetic lock?
Shear locks are indeed electromagnetic, but they also use an interlocking between the armature and the electromagnet. This enhances the holding power, and allows the shear lock to be deployed on bi-swinging doors.
