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

The product mainly consists of two parts: monitoring module and alarm module. This composite fire sensor (temperature and carbon monoxide sensor in one) monitors the temperature and carbon monoxide data in each battery box in real time all day long. The detector collects on-site temperature information and carbon monoxide concentration data in real time and transmits the data to the fire alarm. In the inspection state, the detector indicator light flashes. When a fire occurs in the monitored area and the temperature rises to the alarm threshold, the controller confirms the fire alarm based on the received detector information. At the same time, the detector indicator light is lit and the buzzer alarm is triggered, indicating that a fire alarm has occurred.

The detector is small in size and is mainly suitable for use in the battery box of new energy electric buses. When the temperature or carbon monoxide value in the battery box reaches a predetermined value, a remote alarm will sound, so that the driver can pull over in time and evacuate passengers to ensure passenger safety.
