fire detector

In the automatic fire alarm system, the equipment that explores the scene and finds the fire.

Fire detector is the "sensory organ" of the system, and its function is to monitor whether there is a fire in the environment. Once a fire occurs, the characteristic physical quantities of the fire, such as temperature, smoke, gas and radiation intensity, are converted into electrical signals, and an alarm signal is immediately sent to the fire alarm controller.

Disadvantages: the equipment produced by each company is not universal, independent and positive, not only can't replace each other. They can't communicate with each other.
