Fail-Safe vs. Fail-Secure Locks: Which One is Right for Your Business?

Introduction

When choosing an access control system, one of the most important considerations is whether to use fail-safe or fail-secure locks. These two locking mechanisms serve different purposes and are suited for various security needs. In this guide, we’ll explore the key differences, advantages, and best use cases to help you decide which lock type is best for your business.

What Are Fail-Safe Locks?

Fail-safe locks require power to remain locked. When the power supply is cut off, the lock automatically unlocks. This type of lock is commonly used for safety and emergency exit scenarios where quick egress is required.

Advantages of Fail-Safe Locks:

• Ensures doors unlock in case of a power failure, preventing people from being trapped inside.

• Ideal for fire exits, emergency doors, and high-traffic areas where quick evacuation is necessary.

• Often used with electromagnetic locks (maglocks) due to their reliance on continuous power.

Common Applications:

• Emergency exit doors

• Office buildings with electronic access

• Healthcare facilities

• Schools and universities

What Are Fail-Secure Locks?

Fail-secure locks remain locked when power is lost. These locks require power to unlock, making them a preferred choice for security-focused areas where unauthorised access needs to be prevented, even in power outages.

Advantages of Fail-Secure Locks:

• Keeps doors locked during power failures, maintaining security.

• Suitable for areas requiring high protection, such as server rooms, storage facilities, and restricted zones.

• Works well with electric strike locks, which allow controlled access even during normal operations.

Common Applications:

• Server rooms and data centers

• Cash offices and financial institutions

• Storage rooms with valuable assets

• Industrial and warehouse security doors

Key Differences Between Fail-Safe and Fail-Secure Locks

Feature	Fail-Safe Lock	Fail-Secure Lock
Power Dependency	Requires power to stay locked	Requires power to unlock
Security Focus	Prioritizes safety & quick exit	Prioritizes security & restricted access
Common Usage	Fire exits, emergency doors	High-security rooms, storage areas
Integration	Works best with maglocks	Works best with electric strike locks

Choosing the Right Lock for Your Business

Selecting between fail-safe and fail-secure locks depends on your security priorities:

• If safety is the top concern (e.g., emergency exits, public buildings), fail-safe locks are the better option.

• If security is the primary goal (e.g., protecting valuable assets, restricted access areas), fail-secure locks are ideal.

• Many businesses use a combination of both to balance safety and security across different areas.

Conclusion

Understanding the difference between fail-safe and fail-secure locks is crucial for implementing an effective access control system. Whether you need secure access to restricted areas or a safe exit strategy in emergencies, choosing the right lock ensures optimal functionality.
