Just a quick question on line isolators, how exactly do they work? Are they present for all types of circuits? Or are they used just for circuits that are looped back to the panel?
They are to isolate short from propagating and dragging down the entire circuit. It is used for Class A looped type circuits.
Ok, so how often would a isolator be placed - after how many devices on a circuit? Also what is the general limit to the number of fire alarm devices you can have on a circuit?
