Furthermore, while some high-end devices integrate multiple sensors, they are often difficult to popularize due to their complex structures and high costs. Furthermore, the networking capabilities of these devices are often inflexible, making remote monitoring and immediate alarms difficult to achieve, impacting the efficiency and accuracy of fire prevention and control.

[0014] The following is combined with Figure 1-3 This application is described in further detail.
[0015] A building fire alarm device includes a base 1, a shell 3 and a protective cover 4. A controller 101 is installed at the bottom of the base 1. The controller 101 serves as the system core and controls the operation of various electrical equipment. A photoelectric sensor 102 is installed on one side of the front of the controller 101. The alarm is triggered by detecting the scattering or blocking of light by smoke particles. A networking module 104 is installed on the other side of the front of the controller 101 to achieve remote communication between the device and a fire control center or other intelligent systems, facilitating timely reporting of fires. An ionization sensor 103 is installed on the front of the controller 101 to detect fires by utilizing changes in ions in the air under flames or high temperatures. An ionization chamber 2 is provided at the bottom of the base 1 through the controller 101. The ionization chamber 2 is located at the bottom of the base 1 and is controlled by the controller 101. The ionization chamber 2 can be used to further detect changes in ions in the air and improve the accuracy of fire detection. The outside of the ionization chamber 2 is covered with a shell 3, and a protective cover 4 is provided at the bottom of the shell 3.
[0016] Furthermore, the controller 101 is electrically connected to the photoelectric sensor 102, the ion sensor 103, and the networking module 104. The sensing information of the photoelectric sensor 102 and the ion sensor 103 can be collected through the controller 101. The networking module 104 supports multiple communication protocols, which is convenient for docking with various fire control systems and safety management systems, realizing remote monitoring and instant alarm, and improving the efficiency and response speed of fire prevention and control.
[0017] Furthermore, the top of the shell 3 is snap-fitted with the bottom of the base 1 . Since the shell 3 is snap-fitted with the base 1 , it plays a protective and fixing role and is easy to disassemble and maintain.
[0018] Furthermore, the protective cover 4 adopts a hollow design, which neither affects the normal operation of the sensor nor prevents external objects from directly contacting the ionization chamber 2 and the sensor, thereby improving the safety of the device.
[0019] The standard parts used in this utility model can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.
[0020] The implementation principle of the building fire alarm device of the embodiment of the present application is as follows: after the device is installed, the photoelectric sensor 102 is used to detect smoke particles, thereby improving the detection sensitivity at the early stage of a fire. The ionization sensor 103 effectively identifies different types of fires, including smoldering fires, by detecting changes in ion concentration in the air, thereby reducing the false alarm rate. The data is then transmitted to the networking module 104 via the controller 101. The networking module 104 ensures that the device can seamlessly connect with the fire control center or other security systems to achieve remote monitoring and immediate alarms. The ionization chamber 2 is used to assist the operation of the ionization sensor 103, further enhancing the detection capability of fire characteristics through ionization. The ionization chamber 2 is completely covered by the housing 3 to protect the internal components from external interference and damage.
[0021] This device is not only suitable for general buildings, but can also be customized and expanded according to needs, such as adding other types of sensors, optimizing networking functions, etc. In actual applications, it can be flexibly configured and adjusted according to specific needs.
