HB-DYB LCD-PMS series fire equipment power supply monitoring system

The series of fire equipment power monitoring system consists of three parts: fire equipment power status monitor host (hereinafter referred to as the monitor host), fire equipment power status monitor module (hereinafter referred to as the monitor module) and various sensors. Main functions and features ◎ Monitor the three-phase AC voltage, three-phase AC current, residual current, temperature and switch status of fire equipment power supply ◎ Provide alarms for undervoltage, overvoltage, overcurrent, phase loss, residual current overvalue and overtemperature. Functions ◎The monitoring module itself has sound and light alarm functions, alarm value setting functions, record query functions and self-test functions ◎Real-time display of fire equipment power supply operating status parameters and fault alarm parameters ◎Alarm thresholds, addresses, current transformer types, etc. can be set Parameters ◎ Can communicate with the electrical host of monitoring fire protection equipment and transmit data to the host in real time ◎ One set of normally open output terminals and one set of normally open input terminals. (Can collect switch status) Scope of application: AC single and three-phase fire equipment distribution circuits. Main technical parameters: Main monitoring and alarm function and range Note: AC current sampling uses an external AC current transformer, and the output is divided into 3 levels. The AC voltage sampling is directly taken from B, to the internal voltage reduction of the module (no voltage transformer is used), and the sampling range is. : Residual current sampling sampling zero sequence transformer:.. Platinum resistors are used for temperature sampling. The design of the fire equipment power supply monitoring system is based on the "General Technical Requirements for Fire Control Rooms" - "Fire Protection Code for Architectural Design" - "Intelligent Building Design Standards" B/- "Civil Building Electrical Design Code" - Product Implementation Standard "Fire Protection Equipment Power Monitoring System" , the National Standardization Administration Committee recently approved and released the standard, which will be implemented on the year, month, and day. . The fire equipment power supply monitoring system is an important part of the building fire protection system. It consists of some or all equipment such as fire equipment power status monitors, voltage sensors, current sensors, and voltage/current sensors. The system collects voltage/current signals of on-site fire protection equipment through sensors and transmits them to the fire protection equipment power status monitor to monitor the working status of the main power supply and backup power supply of all fire protection equipment in the building. When overvoltage, undervoltage, overcurrent, or shortage occur in the power supply, In case of equal failure, an alarm signal can be sent to ensure the normal power supply of each fire protection equipment in the building fire protection system, thereby ensuring the stable operation of the fire protection system. , "Firefighting Equipment Power Supply Monitoring System" stipulates the definition, composition, technical requirements, test methods, inspection rules and signs of firefighting equipment power supply monitoring systems. The standard covers the performance of main components (devices), basic functions, voltage and error of collected output signals, shell protection performance, insulation resistance, electrical strength, electromagnetic compatibility performance, climate resistance, mechanical environment adaptability, and products of the fire equipment power supply monitoring system. Specific requirements are set out in the instructions, etc. This standard is formulated for the first time. The technical requirements and test methods of the standard are advanced and reasonable. They can comprehensively and scientifically assess the overall performance of the fire protection equipment power supply monitoring system to ensure its effectiveness and reliability. The release of this standard will play an important role in promoting the widespread application of power supply monitoring systems for fire protection equipment and strengthening product quality supervision and management.

Liu Xiaoxia - Firefighting equipment power supply - AC or DC power supply for various firefighting equipment, including main power supply and backup power supply. Fire equipment monitoring system - a monitoring system used to monitor the working status of the power supply of fire fighting equipment and can send out alarm signals when overvoltage, undervoltage, phase loss, phase misalignment, overcurrent and other faults occur in the power supply. It consists of some or all equipment such as fire equipment power status monitor, voltage sensor, current sensor, voltage/current sensor, etc. Scope of application: Suitable for power supply monitoring of fire protection equipment in newly built, expanded and renovated industrial and civil buildings. Fire protection facilities and equipment include: fire control room, automatic fire alarm system, fire hydrant system, automatic sprinkler system, gas fire extinguishing system, foam fire extinguishing system, dry powder fire extinguishing system, smoke prevention and exhaust system, fire shutter, fire elevator, emergency broadcast , emergency lighting, etc. The structure and composition of the monitoring system. The sensors are divided into current transformers, residual current transformers, and temperature sensors. The voltage signal samples are directly taken, B, and reduced inside the module, so there is no need to configure sensors. The working status parameters of the fire equipment power supply (voltage, current, residual current, temperature inside the distribution box and other basic parameters) are dynamically collected through sensors and the collected signals are transmitted to the monitor module. The collected parameters are displayed on the LCD of the monitor module in real time. On the screen, it is convenient for staff to observe changes in power status parameters in a timely manner. The monitor modules and monitor hosts distributed at each required monitoring point are connected by two buses to form an overall network. This network is the fire equipment power supply monitoring system. The power supply for the monitor module is provided by the monitor host.
