The Rosslare S-805 is a supervised input expansion board designed for the Rosslare AC-825IP networked access control panel. It adds 16 supervised inputs to extend monitoring and control capacity in professional access control installations. This expansion module can be installed directly on top of the AC-825IP controller or mounted separately on a wall or DIN rail. It communicates with the host controller through the RS-485 OSDP/RSDP-Bus serial connection. The S-805 supports 16 supervised inputs for general-purpose and security applications, making it suitable for door status monitoring, alarm points, auxiliary inputs, and other access control system signals. Built for indoor installations, the board operates from 12-16 VDC and includes LED feedback for power status. Input functions are configured through Rosslare AxTraxNG software as part of the AC-825IP access control system.
