ABSTRACT:
A weather-proof notification device includes an enclosure having an integrally formed grille and a speaker located within and attached to the enclosure proximate the grille. The grille is configured to inhibit the entry of rainwater into the interior of the enclosure. A water-resistant or water-tight seal is provided between the speaker and the enclosure, and the speaker includes a water-repellent diaphragm, in order to prevent water from migrating from the sound chamber into the operating electrical compartment. A drain is provided on the grille to permit free drainage of water from the sound chamber.
