A magnetic lock (electromagnetic lock) is an electronic security system that secures doors using magnetic force. In this system, the door is held shut by a powerful electromagnet powered by electricity and is released when the power is cut.

Working Principle of Magnetic Locks:
The electromagnet installed on the door frame and the metal plate (armature plate) attached to the door leaf come together.
When an electric current is applied, the magnet attracts the metal plate, locking the door securely.
When the power is cut or an authorized person triggers the system via card, fingerprint, password, or button, the magnet deactivates, and the door opens.

Advantages of Magnetic Locks:
Silent and Durable: Operates silently. Since there are no moving mechanical parts, friction and wear are minimal, ensuring a long service life.
Remote Control: Can be integrated with card readers, keypads, fingerprint scanners, or central management systems.
High Holding Force: Capable of providing a holding force ranging between 180 kg – 600 kg.
Safety (Fail-Safe): Can be integrated with fire or emergency systems. In case of a power outage or emergency, the door unlocks automatically (Fail-Safe principle), allowing for safe evacuation.

Usage Areas: 

It is widely used for Glass, Wooden, Metal, Aluminum, and Fire Exit doors.

In access control systems, the system's response to a power outage varies depending on the type of device used and the installation configuration.

1. Door Status During Power Outages
Fail Safe (Unlocked when De-energized): The door unlocks automatically when power is cut. This system is generally preferred for fire exits and emergency evacuation doors to ensure safety.
Fail Secure (Locked when De-energized): The door remains locked when power is cut. This method is used in high-security areas such as offices, warehouses, and data centers where security is the priority.

2. Use of Backup Power Supply (UPS or Battery)

 In professional access control systems, a UPS (Uninterruptible Power Supply) is used to ensure the system continues to operate for a certain period during a power outage. Turnstiles, card readers, magnetic locks, and control panels remain active and functional during this time.

3. Manual or Emergency Access Options
For Turnstiles: When power is lost, the turnstile arm allows free passage, or the automatic drop-arm mechanism activates to clear the path.

For Door Systems: Access can be granted via an emergency break glass button or a manual release mechanism.
Recommendations for System Integrity To maintain security and accessibility during power outages, we recommend:
Using UPS support,
Selecting the correct lock type (Fail Safe / Fail Secure),
Installing emergency exit buttons.
