Applied in the G7 series fire alarm two-line system, the loop repeater is used to extend communication distance and increase load capacity. Each additional one can extend 1000 meters or increase load capacity by 1.2A. The input/output is electrically isolated. When the external device connected to the device operates, the loop repeater 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 detect whether the short circuit has been 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.
