What is the function of smoke detectors in the fire detection system?

The function of smoke detectors in the fire detection system is to identify the presence of smoke and alert the crew. Smoke detectors are vital safety devices designed to detect smoke particles in the air, which is a key indication of fire. When smoke is detected, the system activates alarms to alert the flight crew, allowing them to take appropriate actions to ensure the safety of everyone on board.

In aviation, timely detection of smoke is critical, as it can indicate potential fire hazards that may require immediate response, such as deploying fire suppression systems or executing emergency procedures. By effectively alerting the crew to the presence of smoke, these detectors significantly enhance the safety measures in the aircraft, enabling prompt reactions to fire-related emergencies.
