Fire Alarm Model

Fire Alarm Model – Bimetallic Strip Heat Detection Demonstrator

The Fire Alarm Model is a practical educational apparatus that demonstrates how heat can activate an electrical alarm circuit using a bimetallic strip. Supplied by Elmo Agencies, a manufacturer in Ambala, this model helps students understand the basic relationship between heat, thermal expansion, electrical circuits, and alarm systems.

A Fire Alarm Model is a classroom demonstration apparatus designed to explain a basic heat-activated alarm mechanism. It uses a bimetallic strip, which bends when heated because its two bonded metals expand at different rates. This movement can operate a contact in an electrical circuit and activate a buzzer.

When the bimetallic strip is exposed to heat, the two metals expand differently, causing the strip to bend. Once it reaches the required position, it can make or break an electrical contact, allowing the 9V battery-powered buzzer to operate. This gives students a simple visual and audible demonstration of heat detection.
