EN 14846 – Electromechanically Operated Locks

Standard: EN 14846:2008

EN 14846 specifies requirements for electromechanically operated locks and latches. These locks are controlled by an electrical signal and are used in access control systems. The standard covers safety, durability, and compatibility with building automation and security systems.

Key Requirements

• Electrical operation and compatibility with access control systems
• Durability (operating cycles)
• Mechanical strength and resistance to forced entry
• Fail-safe and fail-secure behavior (fail-unlocked vs fail-locked)
• Monitoring outputs (door position, bolt status, sabotage)

Fail-Locked vs Fail-Unlocked

Electromechanical locks can be configured to behave differently when power is lost. Fail-locked (fail-secure) means the lock remains locked—suitable for security-critical applications. Fail-unlocked (fail-safe) means the lock releases—often required for evacuation routes. The choice depends on your fire safety and security requirements.

Evacuation and Panic Hardware

Many electromechanical locks used in doorsets support evacuation via EN 179 or EN 1125 compliant hardware. Split spindle variants allow electric control on the outside while the inside handle or panic bar provides mechanical release without power.
