ABSTRACT:
A novel modular audible signaling device is provided capable of expanded functionality, such as the provision of visual signaling as well. A piezoelectric transducer audible alarm signaling device is provided with an assembly having a housing defining an interior holding a piezoelectric transducer, the housing having a first exterior portion for attachment to a surface and a second exterior portion extending beyond the surface, wherein the first exterior portion and the second exterior portion comprise at least one pair of communicating apertures whereby an electrical conductor may extend through the at least one pair of apertures to the surface. In another aspect, a piezoelectric transducer assembly is provided having a housing defining an interior and a surface, the housing holding a piezoelectric transducer, wherein the housing further comprises an illumination element associated the surface thereof, the illumination element having one or more conductors which extend through the interior of the housing, whereby the illumination element may be electrically inserted into the same electrical circuit as the piezoelectric transducer.
