EVFH-TCQ01-ZY
The product mainly consists of two parts: monitoring module and alarm module. This composite fire sensor (integrating temperature and carbon monoxide sensors) monitors the temperature and carbon monoxide data inside each battery box in real-time around the clock. The detector collects real-time temperature information and carbon monoxide concentration data on site, and transmits the data to the fire alarm. When in inspection mode, 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 occurrence of a fire alarm based on the received detector information, and at the same time lights up the detector indicator light, triggering the buzzer alarm to indicate the occurrence of a fire alarm.
The detector has a compact size and is mainly suitable for use in the battery compartment of new energy electric buses. When the temperature or carbon monoxide level inside the battery compartment reaches a predetermined value, it will sound an alarm through a remote alarm, so that drivers can pull over to the side of the road in a timely manner, evacuate passengers, and help improve the safety level of passengers.
1. Built-in CPU imported from Switzerland, with fast computing speed and reliable performance.
2. CAN bus communication facilitates construction wiring and avoids wiring errors.
3. The use of sealed heat-sensitive components enhances resistance to moisture and corrosion.
4. It uses a high-precision carbon monoxide gas sensor with extremely high response speed and accuracy.
5. Adopt a temperature rise compensation algorithm and automatically adjust through software to improve the response ability under different temperature rise conditions.
6. It has the function of detecting and reporting sensor device failure to ensure reliable operation of the system and facilitate maintenance and management.
7. The unique production process can be used normally in high temperature, high humidity, high cold and high altitude environments.
8. ESD electrostatic protection level 12000V, stronger anti-interference ability.
