Early warning smoke detection systems

Finding a fire detection and warning system that is flexible enough to handle the environmental conditions, such as dust and heat, which are present in industrial facilities, is challenging enough.

Add to this the considerations that these facilities can include areas with very different air-flow, temperature and pollution conditions - such as computer and control rooms, warehousing and production areas – and it makes the job of smoke detection exponentially more difficult.

Vesda detectors are highly sensitive smoke detection systems capable of functioning and detecting smoke in the varied range of conditions and applications, which are often part of any typical industrial or manufacturing facility.

The units detect smoke particles at the incipient stage of fire – providing an early warning. Installing an aspirating ‘active’ smoke detection system is the optimum, cost-effective way to avoid a fire in an industrial facility.

By installing an early warning, aspirating smoke detection system one can monitor specific operational areas of the plant; remote and unmanned areas and sites; and diverse temperature range, moisture content, particle density and increased levels of airflow.

In high airflow conditions, where facilities may be partially open due to loading or dispatch, the delayed detection of smoke can mean a delay in arresting a fire before it gets out of control.

Storage racking can impede access and maintenance of conventional detectors, and the size, shape and positioning of stock can obstruct smoke detection, or activate false alarms.

In addition, traditional smoke detection systems have always struggled to distinguish smoke in harsh, dirty, dusty or polluted environments. Atmospheric particles such as dust, ash and oil mist are trapped by Vesda’s physical filtering system, before the air sample enters the detector.

In this way, false alarms are prevented by Vesda’s dust discrimination technology, which electronically filters the effect of particulate from the output signal, thereby also reducing poor detection and shorter detector life.
