* The pre-alarm and alarm levels can slighty differ from the values shown in the table depending
on the detected type of gas.
WARNINGS
- The alarm and detectors should be installed in a place protected from vibrations, water and corrosive
gases, where the ambient temperature does not exceed the value indicated in the technical data. The
station should be installed in a place where the regular presence of people who can alert to the
presence of alarms is guaranteed.
- To prevent false alarms, the detector should be installed away from:
Ÿ Maintenance rooms where solvents, paints or refrigerator gases are handled.
Fruit ripening or storage rooms, as some fruits can emit gases.
Ÿ
Smoke outlets located in confined spaces (carbon dioxide, propane, LPG) or from engines,
Ÿ
generators or motorised machinery (fork-lift trucks, etc.).
Ÿ Particularly damp areas or with the risk of getting wet.
Areas with strong ventilation.
Ÿ
- Do not paint the detector or place it near solvents or paints.
- Neither the alarm or gas detector are suitable for areas classified as potentially explosive.
