The explosion-proof, weatherproof digital WFD EXPROOF call stations enable direct speech connections with other call stations and loudspeaker announcements in potentially explosive environments.
By pressing the robust double toggle intercom buttons, light barriers (opto-couplers) are activated without contact, which allows permanent use in aggressive, humid and also dusty environments, especially in areas with explosive gases and dusts. For special applications, the call station can optionally be manufactured with a protective lacquer. Please contact us for more information.
The call stations are intended for wall mounting and must be earthed.
In cases where wall mounting is not possible, an optional stand column is available.
The WFD EXPROOF call stations cannot be extended with additional enclosures.
