Fire alarm sensor
A device that converts a physical quantity
that characterizes a fire alarm condition into another physical quantity.
According to the nature of the working effect , it can usually be divided into
two categories: parametric fire alarm sensors and generator fire alarm sensors.
Parametric fire alarm sensors can convert physical quantities that characterize
fire alarm conditions into electrical parameters. Generator fire alarm sensors
themselves are an electric energy generator that can directly convert physical
quantities that characterize fire alarm or quasi-fire alarm conditions into
electromotive force.
