Modernization of STT11/MEA11-2 systems
Our Siemens teams can upgrade your STT11/STT12 fire safety central units (CMSI) to STT20, enabling full modernization of your fire safety system. The CMSI is connected to addressable electronic modules (MEA), which are crucial for controlling fire safety devices (DCT) such as fire doors, dampers, shutters, smoke extraction fans, etc. To provide you with a more modern system, we propose completing your installation by introducing new MEA20x modules linked to STT20 units.
