Final answer:
The main fire alarm in your residence hall is designed to detect smoke particles in the air and activate the alarm system. It is connected to a network of sensors and detectors that can detect smoke or heat from various sources, including fires inside buildings.
Step-by-step explanation:
The reason why the smell of smoke when you are sitting at a campfire does not trigger alarm, but the smell of smoke in your residence hall does, is because of the different types of fire alarms involved. The main fire alarm in your residence hall is designed to detect smoke particles in the air and activate the alarm system. It is connected to a network of sensors and detectors that can detect smoke or heat from various sources, including fires inside buildings.
On the other hand, when you are sitting at a campfire, you are surrounded by an open-air environment with no smoke detection system. The fire alarm in your residence hall is specifically designed to detect smoke particles produced by indoor fires, like those caused by faulty wiring, electrical appliances, or cooking incidents.
