What is commonly included in the function of smoke detectors in buildings?

Smoke detectors in buildings are primarily designed to detect the presence of smoke, which is an important indicator of fire. Their primary function is to alert occupants and emergency services to the potential danger, allowing for timely evacuation and response. This detection capability is crucial for enhancing safety and mitigating the risk of injury or damage due to fire.

While illumination, temperature control, and humidity measurement are important in building safety and environmental control, they do not fall under the primary functions of smoke detectors. These systems are specifically engineered with sensors that respond to smoke particles in the air, often using ionization or photoelectric techniques to trigger alarms when smoke is detected. Therefore, the focus on smoke detection is what distinguishes these devices and underscores their critical role in fire safety.
