Sirena CELEREST Electro-Mechanical Siren

Electro-mechanical siren engineered for industrial applications. The device, made up of an electric motor connected to an internal fan, generates a long high-pitched sound. The high frequency sound replicates typical features of a whistle, allowing recognition of this sound from users. An aluminium protective cap, is provided with the siren, increasing resistance to atmospheric agents for outdoor installation. Ideal choice for industrial applications, from general-purpose signalization to warning of impending dangers. 3 sizes (miniCELEREST, CELEREST and superCELEREST) according to the desired sound output. Available in BA versions (low consumption). The ideal installation in vertical position guarantees total effectiveness of the protective cap.
