ATGI

aaThe ATGI spark proof mine telephone is intended for work in underground mine plants in rooms where methane explosion may occur – the first group of explosiveness, category: M1. The structure of the apparatus ensures work in hard exploitative conditions (noise, mechanical exposure, dust, high humidity), while the high level address call signal loudness and a very intensive optical indicator seen from long distance guarantee call effectiveness, even if places of intensified loudness and dust.
ATGI telephones are compatible with any automatic telephone exchange via ZSD or ZSI sparkproof isolation units produced by TELVIS Katowice, or alternatively through AUI-1 Spark proof Subscriber’s Structure produced by TELKOM-TELOS S.A.
The apparatus has the certificate of the European notified laboratory providing it with the IM 1 EExia I feature (the so-called ATEX).
