Applied to the G7 series fire alarm system, the loop relay is used to extend the driving distance. When the external device connected to the device operates, the loop relay will upload the external device operation information to the controller in a transparent manner. When the output line is short circuited, the circuit repeater automatically stops transmitting and receiving codes (the short circuit light is on), and will automatically monitor whether the short circuit is restored. After the short circuit is restored, continue to send and receive codes. Resolve the issue of excessive load after expanding the circuit. To improve signal waveform in the presence of significant environmental interference. Fire protection bus with no polarity distinction.
