An alarm signal is a sound that tells us there is something important that we need to pay attention to. It is kind of like when your mom or dad calls your name loudly and you know that you need to listen and respond, because they are telling you something very important.
An alarm signal can come from different things, like an alarm clock or smoke detector. When you hear this type of alarm, it means that something needs your attention. For instance, when an alarm clock goes off, it is telling you that it is time to wake up and get ready for your day. Similarly, when a smoke detector makes an alarm sound, it means that there could be smoke or fire in your home and you need to get out quickly.
Alarm signals are designed to grab our attention and make sure we respond quickly to whatever situation is happening. They can be very loud or make unique noises so that we know exactly what type of alarm it is and how to respond accordingly. Overall, alarm signals are very important for keeping us safe and on track with our daily routines.
