Working Principles

The RE46C168S16TF operates based on the principle of photoelectric smoke detection. It utilizes a light source and a photosensitive element to detect the presence of smoke particles in the air. When smoke enters the sensing chamber, it scatters the light beam emitted by the light source. The photosensitive element detects this scattered light and triggers the alarm output accordingly.

Detailed Application Field Plans

The RE46C168S16TF is widely used in various fire detection and alarm systems, including:

1. Residential Buildings: Installed in homes and apartments to provide early warning in case of fire.
2. Commercial Establishments: Integrated into office buildings, shopping malls, and hotels to ensure the safety of occupants.
3. Industrial Facilities: Used in factories and warehouses to detect fire hazards and prevent potential disasters.
4. Transportation Systems: Incorporated into trains, airplanes, and ships to enhance fire safety during travel.
5. Public Spaces: Deployed in public areas such as hospitals, schools, and theaters to protect people and property.
