1. Product Overview
SW-AFD series intelligent wireless fire alarm automatic fire extinguishing device provides real-time, intelligent and stable fire monitoring scheme for power transformation and distribution system. This device can provide users with uninterrupted on-line fire monitoring, real-time monitoring of temperature and smoke change trend in the monitoring area of switch cabinet and box transformer, realize the functions of temperature warning, smoke warning, fire warning and rapid fire extinguishing, and effectively improve the operation reliability of equipment, provide users with new environmentally friendly features, safe and efficient fire protection solutions. SW-AFD series intelligent wireless fire alarm automatic fire extinguishing system can be used in electric power, metallurgy, chemical industry, communication, rail transit, construction and other industries.

2. system composition
Intelligent wireless fire alarm automatic fire extinguishing system is mainly composed of alarm fire extinguishing system host, alarm fire extinguishing controller and automatic fire extinguishing device. It is a set of intelligent system with performance requirements of abnormal early warning, fire alarm, automatic fire extinguishing, system process display and fire record management. It has functions of temperature monitoring, smoke monitoring, early warning alarm, automatic fire extinguishing, wireless transmission, centralized management and remote monitoring. The system is mainly installed in relatively closed spaces such as low-voltage switch cabinet, low-voltage distribution box, medium-voltage switch cabinet, new energy box transformer, etc. The intelligent monitor and intelligent fire extinguishing device are directly fixed on the cabinet body board with fixing parts to form a fire extinguishing component. The intelligent management host is wall-hung on the wall and connected with wireless signals of each component.

3. product features

System intelligence, multi-function
The system adopts advanced technology precision chip, sensitive induction, fast response, to avoid false alarms, effectively avoid non-fire causes of false alarm, misoperation. The system uses a large-screen liquid crystal display, a screen to display more information, friendly interface, intuitive, easy to understand. Set "abnormal early warning, fire alarm, automatic fire extinguishing, system process display, fire record management" as one, real-time transmission of various signal messages to mobile phones or background monitoring system, can be monitored anytime and anywhere, powerful. RS232/RS485 serial port information can be converted into TCP/IP format through protocol converter to realize data acquisition in LAN or real-time monitoring through GPRS data acquisition background.

Efficient, stable and reliable
Using a specific wireless signal frequency band to transmit relevant data, strong anti-interference, more efficient, stable and reliable; a more simplified system structure to ensure more stable operation and detection; the automatic fire extinguishing device used is small in size, reliable in start, fast in fire extinguishing and efficient High, high stability, will not affect its equipment. The product is designed with perfect fire extinguishing logic. Firstly, the controller detects the fire parameters in the cabinet, sends out sound and light alarm after exceeding the limit, and uploads the information to the host. After the host notifies the contact person through telephone short message and other methods, the fire extinguishing device is in standby state. In addition to receiving the instructions from the controller, the fire extinguishing device is equipped with a 3-meter extension detector (which can be extended) to detect open fire at key positions in the cabinet, the fire extinguishing device will only be activated when an open flame appears, avoiding false alarms and false triggers.

green environmental protection
The aerosol particles in the automatic fire extinguishing device add K free radical gas, the fire extinguishing speed is faster and safer, and there is no poison and no residue. The ozone depletion potential value (OPP value) of the automatic fire extinguishing device is 0, which has no damage to the ozone layer, and its temperature effect potential value (GWP value) is 0, which will not produce the greenhouse effect and affect the global temperature change, and is green and environmentally friendly.

Flexible networking, strong scalability
The system configuration is extremely flexible and convenient, can be arbitrarily installed in the area to be monitored, to achieve large network coverage monitoring, system 24-hour uninterrupted protection, and self-inspection, to ensure that the distribution environment all-weather fire protection. Using wireless connection, strong scalability, application is very flexible. Customers can freely combine with temperature sensors, temperature sensing cables, sound and light alarms, smoke detectors, etc. according to their own needs, and fire extinguishing devices can be connected in series.

Simple installation and maintenance
Using wireless transmission technology, simple installation, the use of fixed installation, without any wiring, the operation is very simple and convenient, convenient. It overcomes the disadvantages of traditional limited alarm system, such as poor expansion ability and complicated wiring, false alarm caused by line aging and difficult line troubleshooting.
