In the bus system fire alarm system, the whole system usually don’t work because of the short circuit of the part branch . the function of the circuit isolator is: when open circuit occurred on the part branch of the bus, the circuit isolator of the branch will automatically isolate the part of circuit from the bus, which ensure other branch will not be affected. meanwhile the alarm controller will alarm and display the position of the short circuit, which makes it easy to maintenance.
