Dual-scattering ASA technology
Two infrared light sources positioned at forward (60°) and backward (120°) scattering angles enable discrimination between particle sizes, providing equal sensitivity to both smoldering fires and flaming fires.
Why Siemens automatic fire detectors?
Siemens automatic fire detectors deliver reliable fire protection through intelligent Advanced Signal Analysis (ASA) technology. The portfolio spans from simple optical detection to sophisticated multi-sensor systems with dual-scattering analysis, combining forward and backward infrared scattering to distinguish real fires from deceptive phenomena like steam, dust or exhaust.
ASA technology adapts detection parameters to match specific applications, from cleanrooms requiring maximum sensitivity to industrial facilities with high deceptive phenomena. Available detector types include ASA fire detectors with neural fire and CO detection, multi-sensor detectors combining smoke and heat sensing, optical smoke detectors and dedicated heat detectors.
Key benefits
Reduce false alarms in challenging environments
Deploy reliable fire detection in facilities with steam, dust, fibers or artificial aerosols where conventional detectors trigger false alarms, maintaining protection while minimizing costly operational disruptions.
Detect all fire types with the same efficacy
Achieve balanced sensitivity without combining different detector technologies, responding to slow-developing smoldering fires as reliably as fast-moving flaming fires through intelligent signal analysis.
Verify performance without interruptions
Conduct automated detector function tests on-demand or on schedule with DFTtechnology, which stores results in the cloud for access through Siemens service tools while maintaining continuous fire detection capability.
