About This Product
The model links thermal expansion with a simple electric circuit. As the two metals in the strip expand by different amounts, the strip curls until it touches the contact, and the buzzer sounds. It helps students see how heat detectors in buildings respond to a rise in temperature. Schools, colleges and institutes in Dominican Republic, Brazil, South Korea, Equatorial Guinea and Indonesia can order the Fire Alarm Model from Educational Instrument.
