Minerva MF901 Addressable Ion Chamber Smoke Detector
These detectors react to the visible and invisible fire aerosols (products of combustion) and are therefore capable of detecting the early prescence of hot smouldering and flaming fires, such as wood, paper atc.
They are particularly suitable for general applications in all areas and use a dual ionisation chamber in which air is ionised by a single radioactive source (33k Bq Americium 241). The prescence of smoke in the sampling chamber causes a change in the balance voltage, between the two chambers. This is then converted to a current level and transmitted as an analogue value.
