Working Principles
The RE46C140SW16TF utilizes a photoelectric sensing technique to detect smoke particles in the air. When smoke enters the sensing chamber, it scatters light onto a photodiode, generating an electrical signal. This signal is then processed by internal circuitry to determine the presence of smoke. If smoke is detected above the set threshold, an alarm output is activated.
Detailed Application Field Plans
The RE46C140SW16TF is suitable for a wide range of applications including:
- Residential buildings: Provides early warning for occupants in case of fire.
- Commercial establishments: Ensures fire safety compliance and protects valuable assets.
