Description

About this model

The Manual Call Point DC Ex tem por funcionalidade atuar junto ao Sistebut of Detection and Alarm of Fire (SDAI) in areas classificadas of the tipo EX.

The protecao EX (Ex IIB) garante a capacidade of installation in diversos indoor and outdoor environments que contemplem este nivel of classificacao. The medidas construtivas no involucro impedem a propagacao of a explosao of inside the instrument eletrico for a atmosfera explosiva circundante.

The mobility of ser a device wireless tambem garante a capacidade of realocacao of the maneira more simples and rapida possivel, sendo inclusive realizada a quente, ou seja, with o equipamento in funcionamento.

The devices Ex, ou a prova of explosao, sao componentes especialmente designed for operar with seguranca in ambientes with atmosferas potencialmente explosivas, como industrias petroquimicas, refinarias and areas of armazenamento of products inflamaveis. Esses devices sao fabricados for evitar que any spark, calor ou descarga eletrica gerada internalmente cause a ignicao no surrounding environment.
