CKMS-27/1.2-9/-35-ZY
The fixed fire extinguishing system for bus cabins (hereinafter referred to as the "fire extinguishing system") is developed by Jiangsu Zhongyuan Fire Equipment Co., Ltd. and is an intelligent fire protection product. This fire extinguishing system is mainly used in the passenger compartment of buses. In case of a fire, it can handle the initial fire and buy time for passengers to escape.
The fire extinguishing system has self provided power supply, linkage start, real-time fault (open circuit/short circuit/insufficient air pressure) detection function, and supports manual start to release fire extinguishing agent into the cabin. The system adopts an integrated controller that supports data storage, real-time uploading and sharing of data; Relying on the CAN protocol, it can expand multiple linkage methods and communicate with our IoT monitoring cloud platform. It has the characteristics of simple wiring, convenient installation, low power consumption, and strong scalability.
