Conventional fire detectors are often led around by the nose - they interpret harmless water vapor as smoke and trigger false alarms. In contrast, the new Sinteso S-Line fire detectors are largely immune. This saves not only trouble, but above all money, if the fire department comes in vain.

The detectors hide various sensors, for example for heat or smoke, which are linked to ASA technology, an analysis technology newly developed by the building technology specialists from Siemens. For example, if the curtains catch fire in a hospital room, the Sinteso fire detector picks up on the weather: two optical and thermal sensors each detect smoke, heat and the incoming particles. ASA (Advanced Signal Analysis) analyzes the signals and evaluates them. ASA examines the suspended matter by type and size and assesses the situation. For example, it is possible to identify water vapor, which is often responsible for false alarms.

If ASA comes to the conclusion that there is a fire, it sends the information to the headquarters, which activates the alarm and notifies the fire department. The user can adapt the Sinteso detectors to their place of deployment and the danger situation to be expected there. This takes into account parameters such as the risk for persons and special causes of fire or even potential deceptive factors. Smoldering fires in hotel rooms or open fires in a plastic warehouse register the system so much earlier and more reliably.

The deception security of Sinteso is so high that Siemens will take financial damages if the fire detectors trigger a false alarm. The system is currently being launched in Germany and Austria.

The most attentive fire detectors will be presented by Siemens for the first time at the Light + Building fair in Frankfurt from 18 to 22 April. display
