Description

Technical Field

[0001] The utility model relates to the technical field of fire alarm equipment, in particular to an automatic fire alarm device. Background Art

[0002] The fire detector is the "sensory organ" of the system. Its function is to monitor whether there is a fire in the environment. Once there is a fire, it will convert the characteristic physical quantities of the fire, such as temperature, smoke, gas and radiation light intensity, into electrical signals, and immediately send an alarm signal to the fire alarm controller. During the fire, the automatic fire alarm device can transmit the fire signal in a timely and effective manner, thereby ensuring that rescue personnel can arrive at the fire scene as soon as possible for rescue.
