Product Introduction
It is a signal sensor that integrates voltage/current and residual current monitoring functions, complying with the GB28184-2011 standard. It monitors and alarms the voltage, current, residual current, etc. of the fire equipment power supply, and determines the operation status of the power supply, including overvoltage, undervoltage, overcurrent, phase loss, phase error, and power interruption faults. It uploads the data to the state monitor through the RS-485 network for comprehensive analysis and processing. After analyzing and processing, the status monitor indicates the type of fault in the power supply of the fire-fighting equipment and emits an audible and visual alarm signal; It is a monitoring of the power supply of fire-fighting equipment. By detecting parameters such as voltage/current values and switch status of the fire-fighting equipment power supply, it can determine whether there is overvoltage, undervoltage, overload, phase loss, or phase error fault information in the power supply equipment. It is transmitted to the monitoring machine installed in the fire-fighting control center through the MODBUS bus, which displays alarm information, address, and other information, and dynamically stores the alarm information to achieve the function of early warning and safeguard the normal operation of the fire-fighting equipment power supply! The power status monitor for fire-fighting equipment is based on the Chinese standard GB 58184-2011; The fire equipment power relay can communicate and connect with various intelligent signal sensors on the fire power consumption site, collect and convert communication data, and provide 24V DC power supply to the on-site signal sensors. The collected data is then transferred to the fire equipment power status monitor, thus enabling real-time monitoring and feedback of potential fire equipment power hazards at each power consumption site. It also has the function of increasing the communication distance and power supply distance of the system; Based on the requirements of GB28184-2011 "Fire Equipment Power Monitoring System", by detecting parameters such as current value, voltage value, and switch status of the fire equipment power supply, the power supply of the fire equipment is monitored to determine whether there is any fault information such as short circuit, open circuit, overvoltage, undervoltage, overcurrent, phase loss, wrong phase, overload, etc. in the power supply equipment; The proprietary BUS communication system of American KNN company is uploaded to the monitoring machine (monitor), which displays and records information. When a fault occurs, it can promptly sound an alarm, maximizing the safety of the fire linkage system;
