Siemens and its legacy companies have long been pioneers in the development of fire detection technology–a tradition that continues to this day with the introduction of ASAtechnologyTM. ASA stands for Advanced Signal Analysis, a new, patented technology from Siemens Building Technologies Division that provides reliable and false-alarm resistant fire detection for the wide range of applications.
Siemens’ ASAtechnology is a software-based solution that in real time, dynamically compares sensor signal data to sophisticated algorithms to accurately and reliably differentiate between a fire emergency and harmless smoke, steam, or dust.
Current fire detection technology development is focused on “smart” (multi-criteria fire detection) techniques to increase value, simplicity and reliability. Siemens multi-criteria fire detectors integrate 5 sensors (including two optical for forward /backward scattering, two thermal and one CO depending on model) in a single detector. Through ASAtechnology Siemens fire detectors quickly process the sensor array’s signals to determine alarm or monitoring status. Siemens fire detectors provide for the earliest detection of smoke, heat, and CO in any environment, and offer a no false-alarm guarantee. Additionally Siemens detectors are certified a life-safety CO gas detector meeting NFPA 720 and UL 2075 code and standard respectively, feature 26 user-friendly, selectable detection profiles, 9 field-selectable temperature settings and their high sensitivity meets NFPA 76 Very Early Warning Fire Detector criteria.
ASAtechnology makes use of the concept of signatures, figures of merit that characterize an ongoing fire (or non-fire) event, derived from the real-time evaluation of signal characteristics–such as instantaneous amplitude, slope, short-term variations, etc., and then dynamically adapts the response time and the sensitivity of the detector to provide an accurate, conditions-based alarm in response to the ambient elements of the fire emergency.
Siemens line of multi-criteria detectors managed by ASAtechnology can sense danger more quickly, avoid nuisance alarms and provide valuable information for emergency responders. Combined with newer panels and control systems, the devices can also improve reliability and reduce maintenance costs.
