A ‘maglock’ or electromagnetic lock is a locking system that consists of an electromagnetic device and armature plate.
They are most often used in the front doors of tenement stairways to automatically, open the lock when an intercom button has been pressed. They are also typically found on emergency exit doors due to their simple construction.

There are two types of magnetic locking devices. Fail safe or fail secure; a fail-safe system is de-energised when power is lost and remains in the open position whereas a fail-secure system remains locked when all power is lost. The lock system normally has a timer that can be set to keep the lock open; this is either 15 or 30 seconds.

Advantages of using a magnetic lock system includes;

1. Easy installation.
2. Fast operation. When the button is pressed, the lock is opened instantly.
3. Well constructed. These systems can take more abuse than other types of locking systems.
4. Low power consumption.


1. Require constant power to work properly and be secure.
2. Power cuts can cause them to de-energise and fail.
3. More expensive than other systems.
4. Often require additional parts to operate safely
