Aspirating Smoke Detector

Характеристики

1.Visualized smoke concentration: After connecting to the device via a smart terminal, users can view the smoke concentration waveform for a clear understanding of the current smoke situation and facilitate timely adjustments.
2.Utilizes laser cavity detection technology for accurate smoke particle monitoring.
3.Multi-level alarm function: Divided into five alarm stages, with parameter values for each stage customizable to customer needs.
4.Touchscreen LCD user interface (8922/8924) and simple, intuitive operation mode; connects to our fire alarm controller via a two-wire bus.
5.Suitable for energy storage fire protection, large spaces (such as airports and stadiums), warehouses, special locations (cleanrooms, cold storage), and important locations (such as computer rooms and libraries).
