Electronic siren amplifier controller

Abstract

This product is a controller for an electronic siren amplifier that amplifies the sirens and warning sounds emitted by automobiles, especially emergency vehicles such as road maintenance vehicles and fire engines, during emergency driving. By operating the various switches that appear on the front of the product, a pre-registered voice message in the connected electronic siren amplifier is amplified outside the vehicle. The volume of the amplified voice message can also be adjusted by operating the playback volume adjustment switch, and this operation information is displayed on the operating status display unit.
