AI-430

AI-430 ships sound control and alarm system is a behavior used in many different applications, from ships on board to shore-side operations. This system is designed to provide sound warning and alert signals, such as “Attention all hands” and “Fire alarms”. The AI-430 system uses two types of devices – horns and buzzers. Both types are designed to produce sound signals that could alert people in emergency situations.HornsHorns are capable of producing a loud audio output of up to 151 dB. They can be easily attached to any available structure or to the sides of ships. Horns are capable of producing different kinds of sound patterns and ringing intervals. They are mostly used for signaling passing ships, announcing the ship’s arrival into port or announcing emergency situations, such as man-overboard scenarios. Horns are usually driven by air compressors and can be directed in different directions in order to specifically warn the people in certain areas.BuzzersBuzzers are smaller devices than horns, but still capable of producing loud audio warnings. They are usually much smaller in size and can produce up to 110 dB of sound. They are most commonly used on the deck of ships, in order to indicate various warnings, such as “Stow away” or “Beware of stowaways”. Buzzers are usually mounted in the ship’s superstructure and are powered by electrical energy.SirensSirens are very similar to horns and buzzers in terms of their size and the audio output they produce. However, sirens differ in the way the audio sound is produced, as sirens are able to produce a much more intense sound than horns or buzzers. Sirens are used in ships to produce warning signals in very loud and hostile environments, such as sea states 4-6 or engine rooms. They are typically powered by air and capable of producing up to 185 dB of sound.Working PrincipleThe AI-430 system is controlled using an integrated control board. This control board is connected to the electronic logic control (ELC) board, which contains the necessary circuitry for controlling the various sound devices in the system. The ELC board is also connected to the sound horns, buzzers and sirens. The control board is the one responsible for controlling the sound intensity, and the desired sound pattern/tone.The system is powered by a battery which is connected to the control board, and this ensures a continuous power supply even if main power is disabled. The logicboard\'s software is programmed to emit sound signals based on certain conditions, such as emergencies, alarms, and specific warnings.ConclusionThe use of AI-430 ships sound control and alarm system is extremely common in today’s maritime industry. It allows ship specifications and safety regulations to be fulfilled, ensuring secure passage of vessels all around the globe. The system consists of horns, buzzers, and sirens, based on the ship’s specific needs and the specific notification it wants to give. It is powered by batteries and integrated with an electronic control board and the sound devices, which are used to control the intensity and sound pattern/tone.
