Aspirating smoke detector manufacturer AirSense Technology has launched a fully certified hazardous area version of its Stratos-HSSD aspirating detector.
The Stratos-Ex is an ATEX certified detector which is approved for use in hazardous areas where the explosion risk is presented by gases or vapours in ATEX groups A, B or Hydrogen. The Hydrogen classification is of particular interest where battery rooms need to be protected, explains the company, as in certain circumstances accumulators can vent hydrogen, and it claimed to be the highest level of hazardous area certification achieved by an aspirating smoke detector.
The circuitry of the new detector is closely based upon the Stratos-Micra product, but is miniaturised further and housed in a cast aluminium alloy enclosure, with a circular glass viewing window in the lid providing the customary ‘OK’, ‘Fire’ and ‘Fault’ visual signals.
The detector’s filtration system is positioned upstream of the flame traps to prevent them suffering from dust or dirt build-up. The dust filter is also substantially larger in capacity than ‘normal’ aspirating smoke detection system filters because there is no ‘bypass’. As there are no powered parts in the dust-filter assembly, there can be no explosion risk with routine service.
With programming, diagnostic and set-up facilities provided by hard-wired connection over the serial bus, there should be no need to open the enclosure, either at initial commissioning or for subsequent servicing.
Stratos-Ex also employs the AirSense patented ClassiFire perceptive artificial intelligence algorithm and provides four staged warning levels.
