Short circuit isolator (GM711A)

Functional Features:


Applied to the G7 series fire alarm system, string the GM711A short-circuit isolator into each section of the bus or into the junction of the main and branch lines. Once a short circuit occurs in a certain part of the bus circuit, the short-circuit isolator will isolate the faulty part of the circuit from the entire circuit to ensure that other parts of the circuit can work normally. The short-circuit isolator flashes during normal operation and remains on during operation. After the bus of the faulty part is repaired, the short-circuit isolator can automatically resume operation and reintegrate the isolated part into the system. It is recommended to use at least one short-circuit isolator for every 32 address units. The bus has no polarity and meets the requirements of a circular wiring system.
