Answer:

Explanation: An automatic fire alarm in a building's security system is a heat detector that responds to the heat from a fire by setting off an alarm. Some heat detecting fire alarms rely on a bimetallic strip as the temperature sensor. This strip responds to heat by closing a normally open electrical circuit to activate the alarm.
