Tyco 814I detectors are offered for old specifications which still call for ionisation smoke detectors. The 814CH and 814PH detectors offer improved performance and lower false alarms for most smoke detection applications. The 814I nevertheless offers reliable detection of visible and invisible fire aerosols using a dual ionisation chamber in which the air is ionised by a single radioactive source.
In combination with the SmartSense algorithm, the 814I provides early detection of hot smouldering and flaming fires, such as wood, paper etc. Warning: these detectors contain a small amount of radioactive material (typically <33.3kBq Americium 241). They are safe when used as prescribed. Handling, transport and disposal must be done in accordance with Health Department regulations.
