Everybody knows that fire always has the potential to be a real threat to both life and property It is therefore vital to know that personnel and property are reliably and efficiently protected from its outbreak wherever possible. However, should the unthinkable happen and the circumstances come about for combustion to occur, the very least that we would all want is the assurance that we receive the earliest and most reliable detection possible. It is generally accepted that aspirating smoke detection (ASD) is one of the technologies which provides the earliest detection of the incipient stages of combustion. Aspirating smoke detection systems - also widely known as air sampling detection systems - can detect smoke before it is even visible to the human eye. The systems generally consist of a network of independent pipes with one or more sampling apertures that actively draw air into a highly sensitive smoke-sensing chamber. There, the sampled air is precisely and accurately analysed by a scattered-light detector for smoke particles. If smoke particles beyond a preset threshold are detected, the system triggers an immediate alarm. In that way a timely warning is given -along with the opportunity to fully investigate the cause of the alarm. The most appropriate response can then be initiated to stop the fire gaining a hold and thus prevent injury damage and disruption to business.
