Abstract: A method and apparatus for a signaling device includes an audio device that generates either or both an audible output such as a tone and a voice. The output is based upon a status level. The signaling device further includes a light emitting diode (LED) strobe that illuminates in a variety of colors, where the illumination of a specific color is based upon the status level.

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.

Abstract: An explosion-proof industrial signaling device. The explosion-proof industrial signaling device having an explosion-proof housing and a single module with the capability of emitting different colored lights to indicate the operating condition of a machine. The emitted light can be steady or flashing, and controlled by an external PLC or an onboard microprocessor. The PLC or microprocessor interprets incoming information and causes the color of the light or its flashing pattern to change accordingly. The light source maybe an LED.
