This essential component provides the audible warning for your marine engine’s alarm system. When triggered by a sensor (like the one for low oil pressure or high water temperature), the buzzer emits a loud, unmistakable sound to alert the operator of a critical condition. Paired with an indicator panel (like the one shown in the previous image, which contains the warning lights), this buzzer is vital for preventing catastrophic engine failure on all types of vessels, from fishing boats to commercial trawlers. Ensure your safety system is complete with this reliable alarm buzzer.
