CKMS-27/1.2-9/-35-ZY
The bus cabin fixed fire extinguishing system (hereinafter referred to as the "fire extinguishing system") is a new generation of high-tech intelligent products developed by Jiangsu COSCO Fire Fighting Equipment Co., Ltd. This fire extinguishing system is mainly used in bus passenger cabins to control and extinguish initial fires when emergency response is required, buying valuable time for passengers to escape.
The fire extinguishing system has its own power supply, linked start, and real-time fault (open circuit/short circuit/insufficient air pressure) detection functions. The system is started manually to release the fire extinguishing agent into the cabin. It adopts integrated computer control and has functions such as data storage and real-time data upload and sharing. Through the CAN protocol, a variety of linkage methods can be expanded and can communicate with the IoT monitoring cloud platform developed by our company. It has the characteristics of few connection lines, easy installation, low power consumption, strong scalability, stable and reliable system, and fast startup speed.
The fire extinguishing agent is made of highly efficient and environmentally friendly material - S-100-AB-ST water agent fire extinguishing agent, which has the characteristics of -35°C low temperature resistance, high fire extinguishing efficiency, good environmental performance, non-toxic, does not pollute the air, and does not cause corrosion to the human body and decorative parts.
The fire extinguishing system consists of a fire extinguishing device, a main fire extinguishing agent pipeline, a fire extinguishing agent branch pipeline, pipe fittings, nozzles, emergency button switches, and body wiring harnesses. The fire extinguishing device consists of a box, fire extinguishing agent bottle group, main control board, valves, backup power supply, etc.
