Description

Technical Field

[0001] The invention relates to the field of fire alarm, and in particular to a fire alarm device. Background Art

[0002] Fire alarm device refers to a control and indication device in the automatic fire alarm system that is used to receive, display and transmit fire alarm signals, and can send control signals and other auxiliary functions. The fire alarm controller is responsible for providing a stable working power supply for the fire detector, monitoring the working status of the detector and the system itself, receiving, converting and processing the alarm signals output by the fire detector, making sound and light alarms, indicating the specific location and time of the alarm, and performing corresponding auxiliary control tasks. It is the core component of the fire alarm system. Manual fire alarm buttons and fire alarm bells are both fire alarm devices. In addition, there are smoke sensors, temperature sensors and other alarm devices. The main feature of the multi-line fire alarm controller is that its detectors and controllers are connected in a one-to-one correspondence manner. Each detector is connected to the controller with three wires, so it has more connections and is only suitable for small fire alarm controller systems. The main feature of the bus fire alarm controller is that the controller and the detector are connected in a bus (few wires). All detectors are evenly connected in parallel or in series on the bus (generally the number of buses is 2-4), which is easy to install, debug and use, and is suitable for large fire alarm controller systems. In the fire alarm device, there are some incomplete alarm devices such as repeaters, area displays, fire display panels, etc., which can be regarded as the evolution or supplement of the fire alarm controller. When used under specific conditions, they belong to the same fire alarm device as the fire alarm controller. The basic functions of the fire alarm controller are: automatic conversion of main power and backup power, backup power charging function, power failure monitoring function, power supply working status indication function, power supply for detector circuit, detector or system failure sound and light alarm, fire sound and light alarm, fire alarm memory function, clock unit function, fire alarm priority function, sound alarm sound silencing and re-sound alarm function. However, the current fire alarm device does not take into account the emergency treatment equipment, and requires another operating system to complete the fire treatment. Therefore, we designed a fire alarm device. Summary of the invention
