EVFH-TCQ03-ZY

Carbon monoxide and smoke and temperature composite fire detection and alarm device for electric bus lithium-ion power battery box

        The alarm device consists of a detection unit, a control unit, and a display unit. This product can continuously monitor early fire hazards and fire situations inside the lithium battery box, output sound and light alarm signals to the driver in a timely manner, support automatic and manual mode to start the fire extinguishing device, and control the internal fire situation of the battery box; Integrate hazard reporting, fire identification, and emergency firefighting functions.

        The product has compact external dimensions and supports diverse installation methods; Optional adapter plates can be selected as needed to adjust the installation size. The working voltage is DC9-36V, supporting nearby power supply and reducing installation layout restrictions.

The device has the function of displaying carbon monoxide concentration. Operation method: Select "03 Read Data" in the main menu, select the detection unit address (default address 01), press the confirm button to read the value, and display the real-time carbon monoxide detection concentration inside the battery box.
