Explosion proof heavy duty voice sounder FHF Funke Huster Fernsig
ATEX

The STARLINE range of loudspeakers was designed not only for acoustic signalling and emergency communications but also for speech transmission under rugged environmental conditions in potentially explosive areas of group II. The protection degree allows the loudspeaker to be used in the hazardous areas of zones 1 and 2 or 21 and 22. Explosion protection is guaranteed, among other things, by the terminal box of the increased safety protection type. The transformer module is encapsulated by means of a sealing compound, making it gas-tight. The acoustic pressure chamber is isolated from the environment via a special filter (sinter metal). The housing is made entirely of thermoplastic, thereby ensuring a high level of protection against corrosion. An equipotential bonding is unnecessary.
