Voir plus.....The GRF201 analogue addressable multicriteria detector is the same of the GFR200 detector, except for the detection that is not only with optical principle, but the sensing element operates a sophisticated analysis both of temperature variation and smoke quantity. This allows a quick alarm detection united with an alarm rejection, thanks to the simultaneously analysis of the two parameters.
