Klaxon

Okay, so imagine you're in a big building like a school or an office. Sometimes, the people who work or go to school in the building might need to be warned about something important, like a fire or a dangerous situation.

This is where a klaxon comes in. It's a really loud and powerful horn that makes a big noise that everyone can hear, even if they're far away or can't hear well.

When someone needs to give an important warning, they can press a button or pull a lever and the klaxon will start blaring its loud noise. This noise can be heard all over the building like an alarm, telling everyone to pay attention and follow any safety instructions they're given.

So remember, a klaxon is like a really loud horn that helps protect people by getting their attention and warning them about danger.
