XQQW4/1.6-ZY
The hanging heptafluoropropane gas fire extinguishing device is arranged around the dashboard (specific installation location to be determined). The entire system includes fire extinguishing devices, start alarm switches, temperature sensing cables, stainless steel corrugated pipes, and system wiring harnesses (provided by the vehicle manufacturer). The system can monitor the temperature of the battery compartment. When an open flame is detected or the ambient temperature reaches 105 ℃, the temperature sensing cable will melt and conduct a circuit, triggering the fire extinguishing device to start.
The effective fire extinguishing range of the spray pipe nozzle of the fire extinguishing device can cover the wiring harness area under the instrument panel. The alarm controller is arranged on the auxiliary instrument panel, which can display the working status of each fire extinguishing device and achieve independent control of each fire extinguishing device.
