The magnetic lock is well suited for numerous applications; just about any type of opening can be controlled using a magnetic lock. Be it a door, gate or even a window, there is probably a magnetic lock that will fit your customer's needs. The advantages of the magnetic lock (self aligning, low maintenance, durability, tolerance to door miss-alignment and ultra high duty cycle) will help ensure a trouble free and long lasting installation as well. So let's look at some of the most basic applications for magnetic locks, and when to use them.

CONTROLLED ACCESS

This is the most basic type of application possible. It consist of a power source, a switching device and a magnetic lock, and is commonly used in situation where life safety is not an issue or where free access / exit is not desirable. One use of this application is to control materials such as tools, supplies, jewelry or pharmaceuticals. In this situation you would normally use a medium or high security magnetic lock like the Securitron Model M62 (1200lbs dual voltage) or Model M82B (1800lbs dual voltage w/ bond sensor).

The user approaches the opening and uses a PIN number, card or biometric reader to access the materials. Once the job is completed, the materials are returned to the controlled area in the same fashion. All transactions can be logged via audit trail, providing very tight control of the materials. You can also have multiple controls on this type of system that would allow supervisory oversight to override access or allow it freely depending on the situation.

Another commons use for this application is in detention facilities where prisoners are processed. This type of system allows the movement of persons from process to process in a controlled fashion. And the high durability, low maintenance and high duty cycle of the magnetic lock keeps down time for these systems to a minimum.

FREE EXIT

The free exit application is probably the most common application for magnetic locks. In these types of systems, the magnetic lock is used to lock the door and a code compliant egress device or devices are used to release the magnetic lock for unimpeded free exit. The primary use of this application is exterior free exit doors from any type of building, be it a movie theater, auditorium, warehouse or office building.

With the many varieties of magnetic locks, finding a lock to meet the needs of your opening shouldn't be too difficult. First you need to determine the level of security required. In traffic control applications, a lower security magnetic lock with a holding force of 500 to 800 pounds is recommended when you want to limit access but security is not the main concern.

For single doors, something like the Securitron Model 32 dual voltage 600 pound magnetic lock could be used. On double doors, two locks may be used. Or a magnetic lock with a split strike assembly like the Securitron model M62-SS or M82B-SS allow the ease of a single lock installation (i.e. mounting one unit with one electrical connection) with a two strike plates to secure a double opening.

For medium or high security applications, magnetic locks with a holding force of 1000 to 2000 pounds like the Securitron model M62 (1200lbs dual voltage) or model M82B (1800lbs dual voltage w/ bond sensor) would be recommended. One thing to note in this application is door location and door type. In general you will want to use the medium to high security locks in exterior applications and the lower security traffic control locks for interior applications.

The exceptions to this rule are aluminum store front and glass doors. These doors are normally found on the building exterior but are not generally high security doors so on these applications the lower security traffic control locks or at most a medium security lock would be used. The reason for this is simple. If some one really wants to access the area, he or she won't worry about beating the lock, but instead will remove or break the glass.
