WebSep 28, 2024 · How does a bimetallic fire alarm strip work? When the strip is heated by fire, the high-expansion side bends the strip toward an electrical contact. When the strip touches that contact, it completes a circuit that triggers the alarm to sound. The width of the gap between the contacts determines the temperature that will set off the alarm. WebNov 6, 2024 · In This Article. 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.
