As diverse as our fireman's switch is, so are the questions about it!
We know it's not that easy. What does the slave control box do and why a delay circuit? How many surge arresters can I plan for and why? How does this work with the connection to the fire alarm control panel? What does galvanic isolation mean, what is the difference between a control box and a switch box, how does the fireman's switch switch switch off and why can it also switch on again automatically? How does this work with arc-free switching and undervoltage and cable break detection? And above all: How can I dimension the QFire (up to the megawatt range)?
