Kidde-Fenwal AIR Intelligence 33-30621A ASD-640 Basic Detector (NEW IN BOX)

Kidde-Fenwal AIR Intelligence 33-30621A ASD-640 Basic Detector - Aspirating Smoke Detection Unit This high-sensitivity smoke detection system provides early warning capabilities for critical infrastructure environments. - Operating voltage: 24V DC - Detection range: Up to 640 square meters - Sensitivity range: 0.005% to 20% obs/m - IP rating: IP40 enclosure protection - Communication interface: RS485 and relay outputs

Compared to previous generations of aspirating systems, the ASD-640 series offers a more streamlined path to early fire identification in challenging airflows. This unit maintains industry-leading stability in environments where standard optical sensors might struggle with nuisance alarms or air turbulence.

Advanced Sensing and Operational Efficiency

The AIR Intelligence technology utilizes high-intensity laser light scattering to detect microscopic smoke particles long before they reach visible levels. By integrating sophisticated airflow monitoring and intelligent signal processing, this detector ensures reliable performance in server rooms, warehouses, and cleanrooms while significantly reducing the potential for false triggers. The robust internal components are housed in a durable, factory-new enclosure that adheres to rigorous safety standards, facilitating seamless integration into existing life-safety network architectures.
