Fire Sentry SS4/FSC紫外/紅外火焰探測器
Honeywell在2011年底收購的fire sentry公司利用出眾的火焰探測技術用于所有火焰探測產品的設計與制造，此技術早在1884年就開始應用，并且有軍工、航空領域技術背景。fire sentry火焰探測器利用專利的寬頻紅外量子傳感器，FS24三重紅外火焰探測器使用寬頻4.3微米紅外技術的局限性。SS4-A型光電火焰探測儀采用UV/IR探測技術并成功應用于全世界數千處場合中。
·Multi-Spectrum可探測紫外、可見及紅外光光譜
·內置“through the lens”自檢測試
·誤報警屏蔽
·探測所有火災，不僅僅是碳氫和非碳氫類火災
·可調探測精度
·運行于大范圍溫度范圍內
