Salto XS4 Panic Bar Kit (One S).
The XS4 Panic Bar Kit for XS4 One S integrates a Salto reader and lock with a third-party exit device already on the door, with versions keyed to specific brands and models (CISA, NINZ, TESA, ISEO, and many more). Options include UL-listed versions and exit detection. The right kit is chosen from the exact exit device on the door, which we confirm at survey.
Where this model fits
- Adding credentialed entry to an existing exit device
- Code-required exits that keep their current hardware
- UL-listed or exit-detection life-safety requirements
Parent product line
XS4 Panic Bar Kit (One S) is a configuration of the Panic Bars product line. See the parent line page for the full credential stack, PMS integration list, and brand-standard notes that apply across every Panic Bars configuration.
How this model is configured
Every Salto lock is composed to your doors during scoping: finish, mortise and function type, credential technology (BLE, NFC, RFID, with mag-stripe or PIN fallback where needed), and handing. RevKey confirms each selection at the site survey and configures the final composed part number with you, so the lock that ships matches your door prep and brand standard.
Where XS4 Panic Bar Kit (One S) fits, and where it doesn’t
Best for
- Emergency and egress doors that must stay both compliant and access-controlled
- Integrating a Salto reader and lock with an existing third-party exit device (via kit)
- Life-safety requirements needing UL-listed or exit-detection options
Not ideal for
- Standard non-egress interior doors (use a Salto lock)
- Specifying a kit without identifying the exact exit device on the door
- Doors with no code requirement for panic hardware
