Addressable/Conventional Aspirating Smoke Detection System

N-EI8922N/N-EI8924N Addressable/Conventional Aspirating Smoke Detection System

Features

1.Visualization of smoke content, the intelligent terminal can view the wave form of device smoke content after connecting to the device, intuitively feel thecurrent smoke situation,and make adjustments in a timely manner;
2.Adopting the principle of laser cavity detection,accurate monitoring of smoke particles is
achieved;
3.Multilevel alarm function, divided into five alarm stages,and the parameter values for each stage
can be set according to customer needs;
4.Touch CD screen user display interface(8922/8924)and simple and intuitive operation mode,
which can be connected to our fire alarm controller through two buses;
5.Suitable for energy storage fire protection, high-rise spaces(such as airports, sports halls), warehouses, special places(clean rooms,cold storage), important places(such as computer rooms, libraries),and other places.
