Backup Emergency Signaling (RSA) works independently of the control and supervision system (SSiN) and is used to generate sound, light and other alarms. Alarms are generated as a result of defining logical dependencies and inform employees about events at the power station.
From the hardware side, RSA can be divided into the following blocks:
The above functional blocks are connected with each other by galvanically separated communication interfaces. The entire RSA can be connected to other SAS components via an optical network link. The modules are placed in a 19” cassette with an LVDS type bus.
The BAS Signal Acquisition block may consist of the following types of modules:
