This new series offers enhanced features and a contemporary square design with sleek reader surfaces, elegant finishes, and durable materials. Compatible with a wide range of global door standards – including Euro, ANSI, and Scandinavian mortise locks – the XS4 One S is easy to install or retrofit to new and existing doors. It effortlessly integrates with access control platforms such as Space, KS, and Homelok from the same manufacturer to deliver a secure and completely keyless solution. Whether using RFID credentials, mobile digital keys, or PIN code access, users will benefit from contactless entry, making this an ideal solution for hospitality, workspaces, education, residential, and commercial settings.
The XS4 One S series uses technologies such as the Salto Virtual Network (SVN) and BLUEnet wireless connectivity. These allow the new electronic locks to function offline, online, or in a hybrid mode, providing flexibility for buildings with different needs and IT infrastructure. BLUEnet Wireless enables secure, wire-free, and real-time access control with low energy consumption. SVN allows access credentials to update securely through the door network. Together, they deliver a robust, wireless access control solution that is secure, scalable, and simple to manage.
The distinctive square shape is not just aesthetic; it also ensures smooth retrofits and compatibility with the most common door standards worldwide. Its stylish silhouette complements a wide range of architectural styles and interior decor. Seven finishes, multiple handle styles and reader color options are available as well as privacy features with additional alternatives for mechanical override and electronic or mechanical privacy functions. With no hardwiring required, the XS4 One S is energy efficient and can be installed or retrofitted quickly and easily.
