Magnetic Locks: Exploring Their Functionality and Importance in Businesses

In the ever-evolving security world, magnetic locks have emerged as a reliable, efficient, and highly effective means of protecting commercial properties. Known for their robust locking capabilities, magnetic locks are a sound choice for businesses seeking to enhance their security apparatus.

Magnetic locks, or ‘mag locks’ as often called, function on the simple principle of magnetism. When powered, these locks create a strong magnetic field that firmly secures the door, providing an additional layer of security. Unlike traditional locks, ‘mag locks’ lack keyholes, making them immune to lock picking or key duplication threats.

In an era where security is paramount, understanding the functionality and importance of magnetic locks can help businesses make informed decisions about their security measures. The significance of this topic is underscored by the rising incidence of commercial property theft and vandalism, making it crucial for businesses to stay a step ahead in their security strategies. This blog post aims to delve deeper into magnetic locks, discussing their functionality, advantages, and why they are an important consideration for any commercial entity.

What are Magnetic Locks?

Magnetic or electromagnetic locks are locking devices consisting of an electromagnet and an armature plate. The electromagnet part of the lock is attached to the door frame, while the armature plate is attached to the door itself. When the lock is powered, and the door is closed, a current passes through the electromagnet, attracting the armature plate. This attraction or “magnetic force” securely locks the door, preventing unauthorized access.

The functioning of a magnetic lock is simple. When an electric current powers the lock, the electromagnet becomes magnetized. This magnetization creates a strong magnetic field which pulls the armature plate towards the electromagnet, thereby locking the door. When the power is cut, the electromagnetic field disappears, and a spring pulls the armature plate back, unlocking the door. This fail-safe mechanism ensures that the door unlocks during power outages, meeting safety requirements.

Magnetic locks do not require a key to operate. They are typically controlled by a system that can be both manual (like a push button) or automatic (like a card reader or remote control), making them a versatile and keyless solution for modern security needs.

Types of Magnetic Locks

Several types of magnetic locks are available in the market, each with unique features and advantages.

Fail-Safe Magnetic Locks
Fail-Safe Magnetic Locks are the most common type of mag locks. These are designed to unlock when the power supply is interrupted, making them a safe choice during emergencies like fire or power outage. They are best used in high-traffic areas where free exit is necessary.

Fail-Secure Magnetic Locks
On the other hand, Fail-Secure Magnetic Locks remain locked even when the power supply is cut off. This type of lock is ideal for areas requiring high security, as it ensures the door stays locked, preventing unauthorized access.

Delayed Egress Magnetic Locks
Delayed Egress Magnetic Locks are designed to delay the door’s opening for a predetermined period (usually 15 seconds) after giving the unlock command. This feature can deter would-be thieves and enhance overall security.

Biometric Magnetic Locks
Biometric Magnetic Locks provide advanced security features by integrating biometric systems such as fingerprint or retina scanning. This allows for highly secure, personalized access control, offering an effective solution for sensitive areas within a commercial establishment.

Every magnetic lock type has unique advantages and is best suited for different scenarios. Choosing the right type depends on your business’s security needs and requirements.

How Magnetic Locks Work

The operation of magnetic locks is rooted in the basic principles of electromagnetism. Generally, a magnetic lock comprises two main parts: the armature plate and the electromagnet. The electromagnet is attached to the door frame, and the armature plate is fixed. When current is applied to the electromagnet, it becomes magnetized, creating a strong magnetic field. This magnetic field interacts with the armature plate, causing it to be attracted to the electromagnet, thus locking the door.

The strength of a magnetic lock is directly proportional to the amount of current supplied to it. The more the current, the stronger the magnetic field and, consequently, the stronger the lock. Most magnetic locks operate on low-voltage DC power, usually 12 or 24 volts. Even with this low-power input, magnetic locks can exert immense holding force, commonly ranging from 300 lbs to as much as 1200 lbs or more, making them a powerful security measure.

Another vital factor in working a magnetic lock is a control system. Since magnetic locks don’t use keys, they are typically operated by a control system such as a card reader, keypad, remote control, or even a mobile application. Once the control system signals the lock to unlock, the power supply to the electromagnet is interrupted. Without power, the electromagnet demagnetizes, and the magnetic field vanishes. This event allows the spring attached to the armature plate to pull it back, unlocking the door.

This entire process is almost instantaneous, providing a quick and efficient locking and unlocking mechanism. It is also worth noting that magnetic locks are virtually pick-proof due to their design and operational principle, providing a higher level of security against traditional lock-picking methods.

Advantages of Magnetic Locks

Magnetic locks offer several key advantages, making them a top choice for commercial security systems. Here are some of the notable benefits:

  1. High Security: Magnetic locks provide high-level security. They are virtually pick-proof, making them a great choice for highly secure areas.
  2. Durability: Magnetic locks are wear-resistant and have fewer moving parts than traditional ones, making them less prone to mechanical failure.
  3. Ease of Use: With features such as keyless entry and remote access, magnetic locks offer a user-friendly experience.
  4. Fast Operation: The locking and unlocking process is almost instantaneous, making magnetic locks a highly efficient choice.
  5. Integration with Security Systems: Magnetic locks can easily be integrated into security systems, including CCTV and alarm systems, for a comprehensive security solution.
  6. Fail-Safe Option: In the event of a power outage or emergency, fail-safe magnetic locks automatically unlock, allowing for safe egress.
Magnetic Locks Vs. Conventional Locks
  • Security: Conventional locks are susceptible to picking and bumping, whereas magnetic locks are virtually pick-proof.
  • Mechanical Failure: Traditional locks have many moving parts and are, therefore, more susceptible to mechanical failure. In contrast, magnetic locks have fewer moving components, making them more durable and reliable.
  • Access Control: Conventional locks require physical keys for access, which can be lost or duplicated. Magnetic locks, conversely, can be operated through card readers, keypads, or even mobile apps, offering more secure and convenient access control.
  • Integration: While traditional locks can be standalone, magnetic locks can easily be integrated into broader security systems, enhancing the overall security layer.
  • Emergency Situations: In the event of a power outage, fail-safe magnetic locks automatically unlock, providing a safer option compared to conventional locks that would remain locked.

In light of these comparisons, it’s clear that magnetic locks offer superior protection, convenience, and versatility for commercial properties.
