Instant recognition, for fire and non-fire applications

Fire alarm bells are the oldest of the fire alarm warnings and are still the fire signal of choice in some markets. As bells produce a unique sound that is distinctive and unlikely to be confused with any other alarm which is why they are so popular for just fire but non-fire purposes as well, such as in schools or shift changeover.
