The HES FSUNL-24 is a specialized unlatch module engineered to integrate with HES electric locking hardware systems, providing flexible fail-safe and fail-secure operation in access control installations. This accessory module enables controlled latch release mechanisms, ensuring predictable system behavior during power loss events and enhancing overall security infrastructure reliability.
The FSUNL-24 functions as an interface module between access control systems and HES electric locking hardware. It provides dual-mode operation, supporting both fail-safe configurations (door unlocks on power loss) and fail-secure settings (door remains locked on power loss), allowing facilities to select the security posture that best matches their operational requirements. The module integrates seamlessly with existing HES locking systems without requiring hardware replacement.
Ideal for commercial security environments including office buildings, corporate facilities, secure entry points, and facility management installations. The FSUNL-24 is suited for organizations requiring granular control over access control failover behavior and standardized integration with HES electric locking platforms.
