In simple terms, maglocks work by magnetically adhering to a metal counterplate - called the armature plate. The magnet itself is designed with an electrical coil which when powered, creates a strong electro-magnetic field, which is how maglocks can offer such impressive holding forces. This means of course, that maglocks require power to lock. So in the event of power failure, they will fail-safe unlocked , allowing free escape.
Of course, this all relies on the armature plate. This armature plate is a substantial thick piece of steel, secured to the door or frame opposite to where the maglock itself is positioned. When installed correctly, the armature plate will have a degree of 'wiggle-room', allowing it to fully adhere to the magnet, without any gaps - as we all know, one small gap on a magnet significantly reduces its strength, so this fitting knowledge is essential for correct operation and full holding strength.
In addition to this, there will usually be a small 'thrusting magnet' incorporated into the armature plate which is designed so that when the magnet de-energises because the power was removed to unlock the door , if there's any residual magnetism left, this small magnet is designed to repel the magnet from the armature plate, effectively breaking this residual magnetism, allowing the door to be opened. As previously mentioned, all styles of maglocks can be obtained in monitored and unmonitored versions.
In basic terms, monitored maglocks offer an output which allows you to connect a light, an alarm, or wire into a monitoring panel, which will send out a signal when the maglock is energised , letting you know the door is locked.
In most typical applications monitoring is not required, but for some settings it is essential that a sounder or light can be triggered when the door is open or closed - in these applications, getting a monitored maglock is critical. This allows you to have that form of monitoring you require - whether it be audible or visual - or indeed both!
Just bear in mind as these are maglocks and only work when powered, the output will always be for when the maglock is in its energised state, so if you need the alert to be when it's unlocked rather than locked, simply using a handy relay you can achieve this result. There's an array of fitting brackets available for maglocks, namely Z brackets and L brackets , which can be seen in the header image of this article.
With maglocks, they always want to be fitted on the inside of the door, not on the outside. So depending on the direction of the door - inward opening or outward opening - and the space available above the door, you have to make a suitable selection of brackets in order to appropriately mount the maglock and the armature plate.
This is the part most people struggle with, so to make it simple, please take a look at our diagrams:. We hope this article has helped you understand a little more about how maglocks work, and their principle properties and functionality. If you do have any questions however, we're always happy to help and you are more than welcome to contact us with any queries you may have on how electromagnetic locks work - or indeed any other systems or products we sell.
Some access control programs also have smartphone apps with remote locking and unlocking capabilities. Power is required to keep the door locked. This means that electromagnetic locks are fail-safe by default.
Fail-safe locks automatically unlock when the power goes out, enabling people to leave the building safely in case of fire or an emergency. For high-security doors, a backup power supply or battery can be used to ensure that the door remains securely locked even during a power outage.
Electromagnetic locks are designed to be installed at the top of the door and door frame. The magnet is installed on the secure side of the door frame and the armature plate is fixed to the secure side of the door. A range of electromagnetic locks is available for commercial use. The holding force of a particular lock model is determined by the number of metal components in the magnet, surface area of the armature plate and voltage required.
Conventional mag locks can deliver a secure holding force of pounds to over 1, pounds. They are a flexible option for commercial buildings which can be used to secure entry points both outside and inside and installed on many different types of doors. They are often installed on emergency exits , delayed egress and controlled egress doors.
Below are the most useful applications for magnetic locks :. First, mag locks are simple and require relatively little time to install. Installation requires the magnet and armature plate to be installed at the entry point.
With this type of lock, there are no keys needed and no copies to be made. Monitored or Unmonitored. Single or Double. Buy Online. Deedlock Micro Magnetic Locks. Door or Internal Compartments.
