ABSTRACT:
An armored self-contained outdoor/indoor siren assembly which eliminates the need for an additional protective box and an additional tamper switch which are generally used in the prior art installations. The armored siren assembly of the invention consists of a rigid and strong cover member which forms a housing, and a number of horns mounted within the housing in coaxial nested relationshp with one another which not only form a sound chamber for the siren, but also form a protective means for the sound generating unit of the siren to prevent access to the sound generating unit by unauthorized persons. The cover of the assembly, as well as the various horns included in the housing, and the mounting brackets for the horns, may all be formed, for example, of rustproof diecast aluminum.
