How to install electric fire monitoring system in a power distribution cabinet?

We know that electrical fires account for a large proportion of fires. It is important to avoid electrical fires. How to effectively avoid electrical fires? Electrical fire monitoring system can detect leakage, high temperature that caused electrical fire and take action to stop it. So, electric fire monitoring system can stop fire before its occurance. What components are there in an electric fire monitoring system? There are residual current detector, temperature detector, combined electric fire detector and electric fire monitoring panel. How to install the electric fire monitoring system in a power distribution cabinet? 1. Using residual current detector to detect each power circuit. 2. Connect the residual current detector to combined electric fire detector. 2. Using RS485 wire or 2 -wire non-polar bus wire to connect the combined electric fire detector to electric fire monitor panel. Where can I shop the electric fire monitoring equipment? At
