Smoke Detector Technology

 

Smoke Detector Technology

Smoke detectors are safety devices that detect smoke, a key indicator of fire, and provide early warning through alarms. They are widely used in homes, offices, factories, and public buildings to prevent fire-related accidents and save lives.

Types of Smoke Detectors

1. Ionization Smoke Detectors
