Fire alarm systems work by detecting smoke, heat, or flames, then triggering an audible and/or visual alarm to alert occupants to evacuate. The system relies on various components like smoke detectors, heat detectors, and a control panel that monitors these sensors. When a detector senses a potential fire, it sends a signal to the control panel, which then activates the alarm. Sirens, horns, or speakers that produce a loud sound to alert occupants. Strobe lights or flashing beacons that provide a visual warning.

These devices use ionization or photoelectric technology to identify smoke particles in the air. Ionization detectors sense changes in electrical current caused by smoke, while photoelectric detectors use a light beam that is scattered by smoke particles. These kinds of intelligent plug-in smoke detectors are designed for both performance and aesthetics. A ne,w modern, sleek, contemporary design and enhanced optical sensing chamber is engineered to sense smoke produced by a wide range of combustion sources in accordance with more stringent code standards
