It suits industrial storage rooms, power plants and atriums where sunlight or hot motors could fool other detectors. Three infrared sensors with ASAtechnology tell real fires from deceptive phenomena, and it is rated IP67.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eTells real fires from false alarms – three sensors with ASAtechnology distinguish deceptive phenomena from real fires\u003c\/li\u003e\n\u003cli\u003eSees fires that give off no smoke – detects liquid and gas fires without smoke, and organic material fires with smoke\u003c\/li\u003e\n\u003cli\u003eCopes with sunlight and hot machinery – suited to environments with solar radiation or hot motors\u003c\/li\u003e\n\u003cli\u003eFewer false alarms – fuzzy logic and wavelet analysis\u003c\/li\u003e\n\u003cli\u003eIndoors or out – IP67, operating temperature -35…+70 °C\u003c\/li\u003e\n\u003cli\u003eKeeps the rest of the line working – integrated line separator\u003c\/li\u003e\n\u003cli\u003eAddressed or collective – FDnet\/C-NET or a collective detector line\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFor installers\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePower: operating voltage (quiet) DC 12…33 V addressed, DC 14…28 V collective.

It measures infrared radiation, including the hot CO 2 of the flame.\u003c\/p\u003e\n\u003ch4 class=\"product-description-title\"\u003eWill sunlight set it off?\u003c\/h4\u003e\n\u003cp\u003eIt is designed for maximum immunity to interference emitters and sunlight. One of its three sensors measures solar radiation so the detector can tell it apart from a flame.\u003c\/p\u003e\n\u003ch4 class=\"product-description-title\"\u003eWhich control panels does it work with?\u003c\/h4\u003e\n\u003cp\u003eSiemens FDnet\/C-NET systems such as FS20, FS720 and FC360, or a collective detector line on panels such as CZ10 and FC700A.
