1. APPLICATION

Carbon monoxide (CO) is undoubtedly one of the most toxic gases for the human body. Its danger, moreover,
is compounded by the fact that it is odourless, colourless and non-irritating and so absolutely undetectable by
human senses.
The RGS 328 detector is able to detect the presence of carbon monoxide in the air and can, therefore, ensure the
safety of persons in domestic spaces where there are gas appliances.
An output relay can activate devices for changing the air and turning off, where possible, the combustion (e.g. by
closing a shut-off valve for appliances operating on combustible liquids or gases).
