9. DA ECO detector houses a replaceable sensor cartridge which can contain one or two gas sensors VESDA ECO uses the same well proven core sensing technologies that have been successfully used by the gas detection industry for many years see Table 1 VESDA ECO currently employs three core sensing principles Catalytic bead often referred to as Pellistors for the detection of flammable gases Electrochemical cells for the detection of toxic gases and for oxygen deficiency Infrared for the detection of carbon dioxide The majority of gas sensors have a finite life see Table 1 Sensor life is dependant on the type of sensing principle any internal chemistry and the environmental conditions it is exposed to This makes it difficult to precisely predict the end of life for any gas sensor With the exception of the oxygen deficiency detector and the infra red detecting principle used for carbon dioxide these sensing technologies are not failsafe That is to say they do not provide any indication when the operating life has expired Routine typically 6 monthly exposure to test calibration gas is recommended for all gas types to verify gas sensor response and re validate the accuracy of gas concentration readings The test calibration process requires the use of a zero gas and a span gas Zero gas e g clean air for flammable gas detectors Nitrogen for toxic gas and Oxygen deficiency detectors plus span gas e g a known concentrat
