Weatherproof Analogue Call Station, Ex-Proof (WFA-EX) The explosion-proof, Weatherproof Analogue WFA Call Stations provide direct intercom connections to other call stations and PA loudspeaker announcements in potentially explosive environments. When the robust two-way toggle keys are pressed, they activate contactless opto-couplers, which make them suitable for permanent use in aggressive, moist and dusty environments, especially in areas that are enriched with explosive gases and dust. The call stations are designed for wall mounting, and they cannot be expanded with expansion enclosures. dust- and watertight, fiberglassreinforced polyester enclosure two-way toggle keys with optocoupler, 2 lines each active components pressure-proof enclosed integrated pressure chamber loudspeaker and electret microphone connector for Auxiliary Amplifier WFA-EX Call Station, 1 two-way toggle Art.

Only the initial call to the call station is transmitted over the auxiliary loudspeaker. When the call station answers, its internal speaker is automatically used for the rest of the call. After approx. 20 seconds pause in the conversation, the call station returns to using the PA loudspeaker. 25-W Auxiliary Amplifier 1) Art.

Technical Details International Protection (IP) Ratings The protection type of an enclosure is designated as per DIN EN 60529 / IEC 529 (International Electro technical Commission) by a two-digit IP (International Protection) number that indicates the protection level of the enclosure against the penetration of solid objects, dust and water. A typical IP number for weatherproof enclosures is, for example, IP65 1 ). IP 1st Digit: Protection against the penetration of foreign objects IP 2nd Digit: Protection against the penetration of water 0 Not protected 0 Not protected 1 Protected against the penetration of solid objects with a diameter greater than 50 mm 2 Protected against the penetration of solid objects with a diameter greater than 12 mm 3 Protected against the penetration of solid objects with a diameter greater than 2,5 mm 4 Protected against the penetration of solid objects with a diameter greater than 1,0 mm 5 Protected against reaching dangerous parts with a wire, protected against dust accumulation 6 Protected against reaching dangerous parts with a wire, protected against dust penetration 1 Protected against the penetration of vertically falling drops of water 2 Protected against drops of water falling at an angle of up to 15º from the vertical 3 Protected against drops of water falling at an angle of up to 60º from the vertical 4 Protected against water splashes from all directions 5 Protected against water jets from all directions 6 Protected against strong water jets and temporary flooding 7 Protected against temporary submersion in water 8 Protected against permanent submersion in water 1 ) If an IP protection level is not specified for one of the two categories, then the letter X is used instead of the respective digit, e.g., IPX4.

Designation of Explosion-Proof Equipment The designation of devices and protection systems when put to their intended use in potentially explosive areas is determined according to the requirements of EC Directive 94/9/EC. The designation of an approved device must contain the following information (where applicable): II 2G EEx d e ib IIC T4 Conditions in potentially explosive areas II Device group, use above ground 2 Device category, potentially explosive area Zone 1 G/D Combustible substances: gases and vapours/dust particles EEx Manufactured according to DIN EN 50014, IEC 60079-0, VDE 0171 Part 1 Type of Protection / Protection Principle d Pressure-proof housing / release of an explosion to the outside is not possible e Increased safety / prevention of sparks ib Inherent safety of category b / energy limiting of sparks and temperatures Classification of Gases and Vapors IIC Explosion subgroup (C: hydrogen, ethyne/acetylene, carbon disulfide) T4 Temperature class, classification of gases and vapours according to ignition temperature, T4: > 135 to 200 C (permissible surface temperature of electrical components) ms Neumann Elektronik GmbH owns a registered trademark (brand).
