LIGHT AND SOUND EMERGENCY SIGNALING DEVICE Russian patent published in 2007 - IPC G08B21/00 

FIELD: emergency signaling devices, in particular, for announcement of worst-case situations.

SUBSTANCE: light and sound emergency signaling device consists of sound and light signaling blocks, interconnected by means of an electric cable, where light signaling block consists of semiconductor commutator lamps, positioned on the lid of light signaling block and protected by a cap from external influences. Protection of blocks of light and sound signaling from moisture and dust is achieved by rubber packing between the lid and the body. Positioned on the lid of sound signaling block are block of electronic transformer with electronic key of alternating current with microprocessor control, block of clamps, transistor voltage inverter with microprocessor control and mechanism for transforming electromagnetic oscillations. The body, where the light signaling block is positioned, is attached to the body, where sound signaling block is positioned, by means of an overhanging support.

EFFECT: expanded functional capabilities, namely, capacity of light and sound signaling, increased reliability against explosion, high climatic realization from minus 60°C to plus 50°C, resistance to dynamic influence of dust (sand), contained in atmosphere, and of special substances.
