    Choosing an electronic door locks

    The electronic door strike is installed within the door and activated by an intercom or access control system.

    All strikes work on the principle of electronically controlling the temporary free movement of the jaw (striker) allowing for door opening without manual retraction of the latchbolt.

    Ideally, the latch should have a dead-locking facility whereby the latch bolt cannot be forced back into its case because of the action of the snib resting against the electric strike forend. This facility offers extra protection when a strike is fitted to an outward opening door.


    This depends on a number of factors. What level of security is needed? What type of door material is the strike to be fitted to? Single or double door? Is monitoring of the strike required? What power supply unit is to be used in the system? Is the system AC or DC? What else is running off the PSU?


    There are three basic categories.

    1. Light: normally with no quoted holding force or life. Usually AC and used for low cost door entry systems.
    2. Medium: Holding force of at least 1,000lb with guarantees of two or three years.
    3. High: Holding force of at least 3,000lb with guarantees of up to five years. Some are available with UL approval.


    Door material - internal or external, single or double doors.

    Electric strikes can only be used on single action inward OR outward opening doors. For double action swing-through doors other locking solutions like solenoid bolts, magnetic shear locks or double action electric latches are available. Nowadays there are strikes suitable for nearly all door styles and materials, the most popular being timber and aluminum followed by steel, and occasionally, uPVC.

    Potentially, uPVC causes the most problems because of the narrow and often complicated section containing steel reinforcing. Another problem is the fitting of a suitable lock case into the narrow uPVC framing to operate with the strike. If the door contains a multi-point lock it is likely to be impossible to fit an electric strike.

    If the door contains, or can be fitted with a latch, the best option could be to fit a narrow style sash lock and operate with a sash lock strike either in a UK or DIN faceplate format.

    Whilst a sash lock can improve the level of security in any door when the deadlock is thrown, care should be taken to ensure that the bolt is removed prior to attempting the operation of the strike.


    Depending on model, most manufacturers produce strikes with or without a monitoring facility. This function relays back the state of the strike via single point monitoring of the latch in the jaw of the strike or by dual monitoring of both the latch and solenoid operation. For door state monitoring, consideration should be given to using a separate reed switch on the door/frame.


    Fail Open (Power to Lock) or Fail Secure (Power to Open) are features of the electric strike that will be site dependent. For example, if the strikes are tied into the fire alarm system it is likely that they will be required to Fail Open (Fail Unlocked) once power to the strike is removed. Under other circumstances the strike may be required to fail in the locked position requiring the use of a Fail Secure (Power to Open) strike.

    AC OR DC?

    Where security is involved you cannot always expect a low cost AC strike to offer the same level of security that can be achieved by using a more expensive medium/high duty strike. Pick a product that is fit for the purpose. Short-term savings can work out very expensive. Most of the low cost door entry systems operate on AC rather than DC. Alternating Current produces the familiar buzzing sound which is not heard with DC systems, and AC strikes are only available as Fail Secure (Power to Open). More sophisticated systems operate on DC allowing for continuous silent Fail Open (Power to Lock) or Fail Secure (Power to Open) operation.

    Frequently Asked Questions Magnetic Door Locks

    Magnetic door locks work by using a magnet to hold the door closed. The magnet is typically located on the door frame, and the metal armature is located on the door. When the door is closed, the magnet and armature come together and create a strong magnetic force that holds the door in place.

    • Monitored magnetic door locks are connected to a central security system. This allows the system to monitor the status of the door and to generate an alarm if the door is opened without authorization.
    • Monitored magnetic door locks are more secure than non-monitored door locks, but they are also more expensive.
    • Non-monitored magnetic door locks are not connected to a central security system. This means that they cannot generate an alarm if the door is opened without authorization.
    • Non-monitored magnetic door locks are less secure than monitored door locks, but they are also less expensive.
    • Magnetic door locks are used in a variety of commercial and industrial settings, including:
    • Office buildings
    • Schools
    • Hospitals
    • Hotels
    • Retail stores
    • Warehouses
    • Factories

    Magnetic door locks are very difficult to pick or force open, making them a good choice for securing valuable assets. However, it is important to note that no lock is completely foolproof, and a determined thief may still be able to break into a door that is secured with a magnetic lock.

    Installing a magnetic door lock is a relatively simple process that can be completed in a few minutes. The first step is to mark the location of the magnet and armature on the door frame and door. Once the locations are marked, the magnet and armature can be attached using the included screws.

    If your magnetic door lock is not working properly, there are a few things you can check. First, make sure that the magnet and armature are properly aligned. If they are not, the lock will not be able to create a strong enough magnetic force to hold the door closed. Second, check the wiring to make sure that there are no loose or damaged connections. Finally, check the power supply to make sure that it is providing enough power to the lock.

    • Magnetic door locks are very secure. They are difficult to defeat, even by experienced burglars.
    • Magnetic door locks are very reliable. They are not subject to mechanical failure, like traditional door locks.
    • Magnetic door locks are very convenient. They can be opened with a key card, a key fob, or a password.
