The Schlage Utility Software (SUS) mobile app for Android devices is designed specifically for use with the SUS-A cable to set up and act as the link between access control software and select Schlage electronic locks and accessories. The intuitive screen layout of the free SUS mobile app provides easy navigation during use. 

The SUS mobile app and SUS-A cable are used with networked and offline locks to initialize and configure devices, test operational status, perform ongoing system maintenance and update device firmware.

In addition, for offline devices, the SUS solution is utilized to transfer access control data from the Schlage Express access control software (such as authorized user lists) via a mobile device and cable to the locks or accessories. SUS is also utilized to download audit trail information from locks to the mobile device and then transfer that data to Schlage Express for analysis and storage.

The SUS mobile app and cable replace the legacy SUS solution using the Schlage Handheld Device (HHD).
