Is the Salto XS4 One good for high-traffic hotel doors?

Yes. XS4 One is a full ANSI mortise lock built for high-cycle guest-room and corridor doors. It runs roughly 60,000 openings per battery set, typically 24 to 36 months of service at hotel traffic. For very high-traffic main entrances it remains the right Salto choice over the compact XS4 Mini.

What is the difference between XS4 One and XS4 Mini?

They share the same credential stack (BLE, NFC, RFID, PIN), the same PMS integrations, and the same brand mobile-key compliance. XS4 One is a full mortise lock suited to high-traffic doors; XS4 Mini is a compact, indoor, lower-cost escutcheon best for value-tier and extended-stay rooms. When brand standards are silent and the door is high-traffic, XS4 One is the safer call.

Does XS4 One support Apple Wallet keys?

Yes. With 2024 firmware, XS4 One supports Apple Wallet room keys alongside BLE and NFC mobile credentials. RevKey confirms the exact firmware and brand mobile-key program your property is certified to before the order ships.

Can XS4 One be retrofitted onto existing doors?

On most doors with ANSI standard mortise prep, XS4 One drops in without millwork changes. If the door prep cannot be modified (occupied units, historic doors, custom millwork), a Neo cylinder swap is usually the better retrofit even though XS4 One is the stronger lock.

Salto · Code-compliant exit hardware integrated with Salto access

Salto Panic Bars.

Current lineExit hardwareMobile credentials

Salto's panic bars are the exit-hardware side of the system: the push bars that let people out of a fire or emergency exit while the access side stays controlled from outside. Salto offers its own EN 1125-tested panic bars (rim and surface-rod versions), and a large library of XS4 Panic Bar Kits that integrate a Salto reader and lock with third-party exit devices already on the door (Von Duprin, Sargent, Dorma, CISA, TESA, and many more), so a code-required exit can carry a credentialed reader without replacing the whole device. Options include UL-listed versions and exit detection. Because the kits are matched to specific exit-device brands and models, the right part is chosen from the door's existing hardware, which is exactly what we confirm at survey.

Integrations

Panic Bars connects to hotel PMS, guest-journey, and check-in platforms through Salto’s integration ecosystem, which is extensive and updated frequently. Rather than freeze a partial list, we point you to Salto’s own directory for the current set.

Panic-bar kits integrate a Salto reader and lock with the door's exit device; access runs on the standard Salto credential and platform.

Things to think about

The kit is matched to the existing exit device

Most of the catalog is integration kits keyed to specific third-party exit-device brands and models (Von Duprin, Sargent, Dorma, and dozens more). Identifying the exact device on the door is the survey step that determines the right kit; UL-listed and exit-detection options are specified from the life-safety requirements.
