Controller for electronic siren amplifier

Abstract

This product is a controller for an electronic siren amplifier that amplifies the sirens and warning sounds emitted by automobiles, particularly emergency vehicles such as road maintenance vehicles and fire engines, mainly during emergency driving. By operating the various switches that appear on the front of this product, the emergency driving siren sound and warning bell sound generated by the connected electronic siren amplifier will be emitted outside the vehicle. In addition, the emergency driving siren sound and warning bell sound can be stopped by operating the stop switch, and the electronic siren amplifier can be pre-operationally checked by operating the test switch. The first reference front view showing the operating state shows the state when the warning light / siren drive switch is operated. The second reference front view showing the operating state shows the state when the warning bell operation switch is operated. The third reference front view showing the operating state shows the state when the warning light / siren / stop switch is operated. The fourth reference front view showing the operating state shows the state when the warning light / siren / warning bell test switch is operated.
