What is fire Alarm

The Fire Alarm Working Model uses a special sensor that can detect the heat produced by fire, making it more advanced. This sensor works by sensing a type of invisible light called “infrared rays” that fires give off. When it senses these rays, it sets off an electrical signal that activates the alarm. This shows how electricity and fire detection work together to keep people safe.

Having this sensor also helps students understand how important it is to position and set up fire alarms correctly. By seeing how the sensor works in the model, students can learn how to make real fire alarms more reliable. Overall, the model teaches about the science behind fire safety and encourages people to be more aware of how to prevent and deal with fires.
