These detectors react to the visible and invisible fire aerosols(products
of combustion) and are therefore capable of detecting the early presence of hot
smouldering and flaming fires, such as wood, paper etc.
They are particularly suitable for general applications in all areas and use a
dual ionization chamber in which the air is ionised by a single radioactive source(Americium241).
The presence of smoke in the sampling chamber causes a change in the balance voltage,
between the to chambers. This is then compared against an alarm level.
