The Elite and Industrial series of gas sensors for fire-fighting systems are distinguished by the multiplicity of advanced technologies that enable a high degree of accuracy in the detection of flammable, toxic, and explosive gases. In fact, the sensing element can make use of catalytic, pellistor, electrochemical or infrared technology in intercepting the presence of gases, such as methane, carbon monoxide, LPG. The devices can also include a state-of-the-art integrated management microprocessor that gives them maximum reliability and precision, and explosion-proof and dust-proof housings for use in areas with potentially explosive atmospheres. Gas detectors and fire suppression systems protect structures, people and property not only from the risk of fire or explosion, but also from the inhalation of toxic gases that can harm health and prove dangerous.
