Magnetic Door Locks

Magnetic Door Locks, sometimes referred to as mag locks, electromagnetic (EM) lock, or electromagnetic door latch, ensure that doors close automatically and are securely closed. An em lock for a door uses a magnetic field to hold a door closed. The holding force of the door, typically measured in kilograms (kg) or pounds (lb), dictates its security level. Typical ratings for commercial magnetic door locks include 600 lbs, 800 lbs, 1200 lbs and 2,400 lbs of holding force.

Magnetic door locks are designed to suit a variety of domestic and commercial applications and offer solutions where a high-security level is required, such as schools, hospitals or sensitive restricted areas.

How Do Magnetic Locks Work?

Electromagnetic locks, or mag locks, secure doors by generating a powerful magnetic field that bonds an armature plate on the door to the lock body on the frame. The armature plate is a flat steel plate, specifically designed to be attracted by a magnetic field. When electricity flows through the coils within the electromagnetic lock body, it creates a magnetic field. This field strongly attracts the armature plate, holding the door firmly shut.

Access control systems, like keypads or card readers, regulate power flow to the lock, releasing the door upon authorisation. Importantly, these locks are fail-safe, de-energising and unlocking during power outages.

Key Features of Electromagnetic Door Locks

Electromagnetic door locks provide essential security features. Understanding these is key to selecting the right lock.

• Holding Force: This rating, in Newtons (N) or pounds (lbs), indicates the lock's resistance to forced entry. Higher ratings for commercial magnetic door locks, provide increased security. Selecting the correct holding force ensures the lock matches the door type and security needs.
• Power Requirements: These locks typically operate on 12V DC or 24V DC. Matching the lock's voltage to your power supply is important for proper operation.
• Fail-Safe vs. Fail-Secure: Fail-safe locks unlock during power outages, ideal for emergency exits, while fail-secure locks remain locked. Fail-safe is the most common configuration for magnetic locks.
• Compliance and Certifications: Ensure the electromagnetic lock complies with relevant Australian Standards, such as AS 1530.4 (Methods for fire tests on building materials, components and structures) where fire rated doors are used, and also AS/NZS 3000 (Electrical installations) for the electrical installation of the magnetic lock.

Magnetic Door Lock Installation Considerations

Proper installation is crucial for the reliability and security of magnetic door locks. Here are key considerations:

• Proper Door and Frame Assessment: Thoroughly evaluate the door and frame to ensure they can support the weight and force of the electromagnetic lock.
• Secure Mounting for Stability: Use appropriate fasteners and mounting brackets to ensure the lock and armature plate are firmly attached, preventing movement or detachment.
• Correct Alignment for Optimal Performance: Precise alignment between the lock and armature plate is essential for maximum holding force and reliable operation.
• Wiring and Electrical Considerations: Ensure that the building’s voltage and wiring can support the power needed for the electromagnetic lock to function.
• Integration with Access Control Systems: Plan for seamless integration with existing or planned access control systems, such as card readers or keypads.
• Fire Safety and Emergency Egress Compliance: Verify that the installation complies with fire safety regulations and ensures unobstructed emergency egress according to building codes.
• Testing and Final Adjustments: Conduct thorough testing after installation to ensure the lock functions correctly and make any necessary adjustments.
• Professional Installation Consideration: Consider professional installation, especially for complex systems, to ensure compliance and optimal performance.

Avoiding Common Mistakes When Purchasing Magnetic Locks

Choosing the right magnetic lock can be trickier than it seems. It’s easy to get caught up in the security features and forget about the practicalities. Here are some common pitfalls to avoid:

• Neglecting Power Supply Compatibility: A magnetic lock won't function without the correct power supply. Make sure the voltage and current requirements of the lock match your power source. An incompatible power supply can lead to lock failure or even damage to the system.
• Overlooking Door and Frame Compatibility: Not all doors and frames are created equal. The lock's size, mounting style, and holding force must be compatible with your specific door and frame type. Ignoring this can result in improper installation and compromised security.
• Ignoring Compliance Requirements: Magnetic locks often fall under specific building codes and safety regulations. Failing to comply can lead to costly rework and potential legal issues. Always check local regulations before purchasing and installing.
• Underestimating Installation Complexity: While magnetic locks seem simple, proper installation requires precision and expertise. Underestimating the complexity can lead to faulty installations, compromising both security and functionality. Consider professional installation to avoid these headaches.

Industrial and Common Applications of Magnetic Door Locks

Magnetic door locks have become a staple in security systems across diverse industries. Their reliability, ease of use, and robust security features make them ideal for a wide range of applications.

• Commercial Buildings and Offices: In office environments, mag door locks are frequently used for controlling access to secure areas, server rooms, and executive offices. They integrate seamlessly with access control systems, allowing for keycard or biometric entry.
• Healthcare Facilities: Hospitals and clinics rely on magnetic locks to secure sensitive areas like pharmacies, laboratories, and patient records rooms. These locks help maintain security compliance and protect valuable medical equipment.
• Educational Institutions: Schools and universities may utilise electromagnetic door locks to secure classrooms, libraries, and administrative offices. They provide a quick and efficient way to control access after-hours, or during emergencies or lockdowns.
• Industrial Settings: Factories and warehouses use magnetic locks for securing storage areas, hazardous material rooms, and restricted production zones. Their durability and high holding force make them suitable for heavy-duty industrial applications.
• Transportation Hubs: Airports, train stations, and other transportation facilities use magnetic locks to secure restricted areas, such as control rooms and maintenance areas. Their ability to integrate with centralised security systems makes them ideal for managing access in high-traffic environments.
• Residential Buildings: In apartment complexes and gated communities, magnetic locks are used for controlling access to common areas, such as gyms, pools, and parking garages. They enhance security and provide convenience for residents.
