Electronic siren amplifier controller

Abstract

This controller is an electronic siren amplifier controller that amplifies the sirens and warning sounds emitted by automobiles, particularly emergency vehicles such as road maintenance vehicles and fire engines, during emergency maneuvers. Operating various switches on the front of the device enables pre-programmed audio messages to be broadcast outside the vehicle, as well as the sound of an emergency driving siren and warning bell. Operating the stop switch stops the emergency driving siren and warning bell sounds, and operating the test switch verifies the proper operation of the electronic siren amplifier before operating the vehicle equipped with this device. The volume of the amplified audio messages can be adjusted by operating the playback volume adjustment switch, and the operation information is displayed on the operation status display. The reference front view showing the first usage state shows the state when the warning light and siren drive switch is operated. The reference front view showing the second usage state shows the state when the volume switch is operated. The reference front view showing the third usage state shows the state when the warning bell operation switch is operated. The reference front view showing the fourth usage state shows the state when the warning light, siren, and stop switches are operated. The reference front view showing the fifth usage state shows the state when the warning light / siren alarm bell test switch is operated.
