The modularity of this didactic system grants to the students a direct and immediate approach to the topics, offering
the opportunity to study various subjects performing several experiments as following:
• Signalling installation
• Single-control signalling installation
• Reciprocal control signalling installation
• Light signalling installation
• Ringing installation with doors and main entrance control
• Electric lock ringing installation
