Fail Safe vs. Fail Secure Locks: Differences, Uses, and Best Applications

Selecting the right electronic locks and access control systems requires a clear understanding of the differences between fail safe and fail secure mechanisms. Both options serve specific security needs, and selecting the right one can significantly impact the safety and functionality of your property. Here, we break down the key differences and explore the ideal applications for each.

What is a Fail Safe Lock?

A fail safe lock is designed to unlock automatically when power is lost. This ensures that occupants can exit the premises safely in the event of an emergency, such as a fire or power outage.

Key Features of Fail Safe Locks:

• Safety First: Prioritizes easy egress during emergencies.
• Power Dependency: Requires continuous power to remain locked.
• Common Types: Electromagnetic locks (maglocks) are a typical fail safe mechanism.

Applications for Fail Safe Locks:

Fail safe locks are ideal for situations where life safety is the primary concern. Common use cases include:

• Emergency Exits: Ensuring occupants can leave quickly during an evacuation.
• Commercial Buildings: Offices, schools, and hospitals often use fail safe locks on doors that serve as emergency exits.
• High-Traffic Areas: Entrances and exits where people need quick and reliable access.

What is a Fail Secure Lock?

A fail secure lock, on the other hand, remains locked when power is lost. This mechanism is designed to maintain security, preventing unauthorized access even during a power outage.

Key Features of Fail Secure Locks:

• Security First: Ensures that access points remain secure without power.
• Power Dependency: Requires power only to unlock the door.
• Common Types: Electric strikes, and certain electronic deadbolts often operate as fail secure mechanisms.

Applications for Fail Secure Locks:

Fail secure locks are ideal for scenarios where security takes precedence over ease of egress. Common use cases include:

• Server Rooms: Protecting sensitive data and equipment.
• Restricted Areas: Doors leading to vaults, safes, or high-security zones.
• After-Hours Security: Ensuring entrances remain locked during non-operational hours.

Choosing the Right Lock for Your Needs

The choice between fail safe and fail secure locks depends on the specific requirements of your property. Here are some factors to consider:

1. Building Codes and Regulations:

   • Many local codes require fail safe locks for emergency exits.
   • Verify with your local regulations before making a decision.

2. Power Backup Solutions:

   • Consider installing a backup power source (like a UPS) to ensure continuous operation of fail safe or fail secure locks.

3. Hybrid Solutions:

   • In some cases, a combination of fail safe and fail secure locks can provide a balanced solution. For instance, main entrance doors might use fail safe locks, while interior restricted areas use fail secure mechanisms.

Conclusion

Understanding the differences between fail safe and fail secure locks is essential for designing a robust access control system. While fail safe locks prioritize occupant safety, fail secure locks ensure uncompromising security. By assessing your specific needs and consulting with access control experts, you can select the ideal locking mechanisms for your property.
