SimonsVoss launches FORTLOX Series to strengthen security across electrical infrastructure and remote assets

Digital locking specialist SimonsVoss has launched the FORTLOX Series, a new mechatronic locking system designed to help operators secure electrical infrastructure, remote assets and distributed networks.

Developed for environments where resilience, accountability and operational continuity are critical, the FORTLOX Series combines a thumb-turn-free, battery-free digital cylinder with a multifunctional programmable key to provide secure, centrally managed access control across geographically dispersed sites.

The launch comes as operators of electricity networks, substations and critical infrastructure face increasing pressure to strengthen physical security, manage contractor access and maintain operational resilience across remote and often unattended locations.

At the centre of the system is the FORTLOX Cylinder, a battery-free digital cylinder powered directly by the FORTLOX Key. Designed as a direct replacement for conventional mechanical cylinders, it enables infrastructure operators to upgrade security without extensive modifications to existing installations.

The system has been developed specifically for technical infrastructure applications including transformer substations, cable distribution cabinets, EV charging infrastructure, data centres, telecommunications facilities and remote technical sites where secure and traceable access is essential.

Unlike traditional key-based systems, the FORTLOX Series enables operators to issue, update and revoke access permissions remotely. This allows access rights to be assigned to engineers, contractors and service providers for specific tasks, locations and time periods, helping to improve security while reducing administrative overhead.

All user permissions are stored directly on the FORTLOX Key, eliminating the need to programme individual cylinders on-site.

The key can also be synchronised via SmartStick, SmartRelay 3 or smartphone, enabling organisations to manage access rights efficiently across distributed infrastructure networks.

Bruce Donald, UK and Ireland Country Manager at SimonsVoss, said, "As electricity networks continue to expand and infrastructure becomes increasingly distributed, operators need greater control over who can access critical assets and when.

"Many facilities still rely on mechanical locking systems that provide limited visibility and can be difficult to manage across large estates. FORTLOX has been developed to provide a more secure, flexible and resilient approach to physical access management.

"By enabling organisations to remotely manage permissions, issue temporary access rights and maintain a clear audit trail, the system helps infrastructure operators improve security while reducing the operational burden associated with traditional key management."

Designed for demanding environments, the standard FORTLOX Cylinder carries an IP54 protection rating and operates reliably in temperatures ranging from -25°C to +65°C. An IP67-rated version is also available for applications requiring enhanced protection against water and dust ingress.

The battery-free design eliminates the need for on-site battery replacement, making the system particularly suitable for remote and infrequently accessed locations where maintenance visits can be costly and time-consuming.
