Fire alarm sensor

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.
