Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a fire alarm. Background Art

[0002] Heat detectors are used to detect fires or smoke in the early stages of a fire. They are widely used in industrial, commercial, and residential buildings, as well as in vehicles, offshore platforms, and facilities. Heat detectors issue fire alarm signals in the early stages of a fire, before smoke and flame detectors do. Therefore, their rapid early warning can effectively reduce fire damage. In the early stages of a fire, the burning material releases a significant amount of heat. As the temperature continues to rise, the heat-sensing element within the heat detector changes. Responding to abnormal temperatures, temperature rates, and temperature differences, the detector converts the temperature signal into an electrical signal, which is then transmitted via a transmission bus to the fire alarm controller in the fire room, triggering an alarm. However, this process takes time. When a fire is large, this wastes time escaping. If occupants are asleep or in rooms with poor soundproofing, they may not hear the external alarm in time, reducing their chances of escape.

[0003] As can be seen from the above, the existing technology has the problem of poor alarm effect of fire alarm. Utility Model Content
