Fire alarm system
Non-polar two-bus communication, 24V power supply mode, reliable use. Built-in application-specific integrated chip, bus, input line, output line are isolated design, reduce the impact of external interference, input can be set to normally open or normally closed mode, software and hardware multistage filtering, improve anti-interference ability.
