The detector is configured to sense photo-luminescent fire products, particularly polyaromatic compounds, and actuate an alarm when signal levels indicate a dangerous/fire condition is present. The photo-luminescence detector may be combined with optical scatter or other fire detectors to improve discrimination between fires and false alarm sources."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Combustion product detection","description":"A smoke detector comprising an enclosure communicating with an external environment, within the enclosure a light source illuminating a detection volume in a first wavelength band and a light-sensor r","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11250681","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
