Electrical fire monitoring equipment and DH12A, DH01B and DH230 electrical fire detectors form an electrical fire monitoring system with bus communication, each detector has its own independent coded address, and the electrical fire monitoring equipment is connected with each detector through two bus loops, that is, it communicates and provides power for each device, and the alarm information is reported to the control panel through interrupt mode. * JB-DH-TC5600 Electrical Fire Monitoring Equipment and DH12A, DH01B, DH230 electrical fire detectors constitute the bus-communication electrical fire monitoring system. The electrical fire monitoring equipment communicates with each detector having its own independent address, through the two buses, which is the communication, and the power also supports each device. The alarm information is reported to the host through the interrupt mode to achieve high efficiency and rapid response. At the same time, each channel of…
