[0002] Fire alarm equipment involves many aspects. Fire hazards have become one of the major safety hazards in urban people's lives. Every year, there are many large and small fires that cause serious damage to people's lives and property. The fire prevention situation is urgent. Fire alarms are one of the most important means of preventing fires.

[0003] Specifically, the essence of a fire alarm is to detect the presence of smoke through a smoke sensor, and then trigger an alarm based on the presence of smoke. Fire prevention is generally achieved by monitoring the concentration of smoke. An ion smoke sensor is used internally. The ion smoke sensor is a technologically advanced sensor that is stable and reliable in operation. It is widely used in various fire alarm systems, and its performance is far superior to that of gas sensitive resistor fire alarms.
