In a fire, heat increases the temperature of the fire alarm.
ReplyDeleteTemperature causes the bimetal to expand or outside the coil. This "closeness" of the route or close to the circuit to activate an alarm in this case, a fire alarm.
Bimetal responds to temperature - the two metals differing thermal expansion and changes in band shape, with a rise in temperature.
