Which of the following does NOT function as part of a fire detection and alarm system?

1. Smoke detectors

2. Heat detectors

3. Automatic doors that lock when the alarm activates

4. Alarm notification appliances

The correct answer is: Automatic doors that lock when the alarm activates

The correct response highlights that automatic doors that lock when the alarm activates do not function as part of a fire detection and alarm system. A fire detection and alarm system is primarily designed to identify the presence of fire, smoke, or heat and to alert occupants and emergency services accordingly. Smoke detectors, heat detectors, and alarm notification appliances all serve specific roles within this system. Smoke detectors sense particles produced by combustion; heat detectors respond to changes in temperature indicative of a fire; and alarm notification appliances, such as horns, bells, or strobe lights, provide audible and visual alerts to inform people of a fire situation. On the other hand, while automatic doors may enhance safety and building evacuation procedures during a fire emergency by controlling access or egress, they are not integral to the core functionality of detecting fires or giving alarms. Their locking mechanism is more about security or containment rather than detection or notification in the event of a fire.
