Aspirating Smoke Detector: D9000 FLOW- 1/2/3/4
NEWLY DEVELOPED
ASD
detector
D9000 FLOW-1/2/3/4
Features
The DMTech ASD aspirating smoke detector is a highly sensitive detector for early detection of fire, engineered to analyze air samples via an aspiration system.
The device operates on the principle of optical smoke aerosol detection by analyzing light scattering and attenuation, utilizing an innovative combination of optical methods to achieve significantly increased sensitivity and reliability.
The detector can operate standalone or integrated into a fire alarm system.
It is suitable for facilities with challenging detection conditions, such as:
Server rooms
Electrical cabinets
High-rack warehouses
Cold storage rooms / Walk-in freezers
Technical / Equipment rooms
Innovative Technology
The device implements a patented method (BG3757U1) for the detection of smoke aerosols, based on two light sources—blue (430) and infrared (870–900)—and two photosensitive receivers.
A key innovation is the combined analysis of three signals: scattered infrared light, scattered blue light, and blue light attenuation.
This enables the detection of “invisible” smoke (smoke without visible coloration), significantly reduces false alarms, and ensures earlier detection.
