It can be used to make a fire alarm by attaching it to another metal object i.e a nail and and adding a buzzer and some batteries and heating a busin burner underneath the bimetallic strip. This will make the strip curl upwards and touch the nail. This will make the buzzer go off

Why do you use a bimetallic strip in fire alarms?
Bimetalic strips are composed of two metals with different properties in the case of fire alarms it is the difference in thermal expansion that is important. When the strip is heated (due to a fire) the strip bend and can complete an electric circuit setting off the alarm.

A bimetallic strip can be used as a thermostst in a simple fire alarm system Explain in detail how a fire would cause the alarm to sound And describe how it could be activated at a lower temperature.?
a fire would bend the strip which would complete the circuit for an alarm. When cooled, it might complete another circuit, answering your second question.
Why does a bimetallic strip consist of 2 metals?
A bimetallic strip consist of two metals in order to detect rapid changes in temperature. Used in conjunction with some fire alarm systems, bimetal strips will detect rapid changes in temperature using the differences in expansion rate of the two metals. As one half of the strip expands more rapidly than the other, it will cause the strip to bow or bend causing it to touch a nearby contact sensor thus activating the ' rate of rise' temperature sensor, which may or may not be tied into an alarm system.
