The WFA-EXPROOF Weatherproof Analogue Call Stations enable direct voice connections with other call stations and loudspeaker announcements in potentially explosive environments.
When the robust double-toggle call buttons are pressed, light barriers (opto-couplers) are activated without contact, which allows permanent use in aggressive, damp and also dusty environments, especially in areas enriched with explosive gases and dusts.
The call stations are particularly energy efficient.
