Final answer:
In a smoke detector, audio and visual indicators occur to warn people of a potential fire.
Step-by-step explanation:
In a smoke detector, if smoke is detected in a cabin, there are usually audio and visual indicators that occur to warn people of a potential fire. These indicators include:
- Audio alarm: The smoke detector emits a loud sound or alarm to alert occupants of the cabin.
- Visual alert: A visual indicator such as a flashing light or LED may also be present to grab attention.
These indicators work together to ensure that people are alerted immediately and can take appropriate action to evacuate or address the fire.
Smoke alarms detect fires by sensing small particles in the air using a couple of different kinds of technologies. Once they detect those particles above a certain level, they signal the alarm to sound so that you and your family can get to safety and call 911. Smoke alarms save lives.
There are two basic types of passive smoke detectors: photoelectric (optical) and ionization (physical process). A combination of the two types of alarm (dual sensor smoke alarm) is recommended for maximum protection from both fast flaming and slow smoldering fires.
