Invisible Design: Salto Brings Ælement Fusion to Exterior Doors

Salto Systems has expanded its Ælement Fusion smart locking range with a new version designed for exterior doors and installations exposed to demanding weather conditions. The launch marks a significant extension of the existing solution, bringing Salto’s signature “invisible” locking concept to hotel entrances, premium residential developments, and other outdoor applications for the first time.

The system retains its minimalist design, with no visible electronic lock hardware on the door surface. All key components—including the electronics, battery packs, and control modules—are concealed inside the door, while users interact through a discreet circular reader compatible with smart credentials, mobile keys, and Wallet technology.

The new version has been specifically engineered for outdoor environments and features climate-resistant gaskets that protect the system against rain, humidity, and extreme temperatures. With an IP55 rating for dust and water protection, it allows property owners to maintain the same clean architectural design across all doors, from hotel rooms and apartments to main entrances and shared spaces.

At the same time, Ælement Fusion integrates seamlessly with Salto’s smart access ecosystem, supporting real-time management, mobile credentials, and centralized access administration.

“With this launch, we have bridged the gap between weather resistance and premium architectural design. Property operators no longer need to choose between aesthetics and the robustness required for exterior environments, as Ælement Fusion combines both in a single solution,” Salto said.
