This system consists of a highly sensitive, latest generation active aspirating smoke detector, in addition to pre-alarm signalling and contamination detection. It can set its sensitivity according to the application it is intended for. Using an ABS aspirating pipe and the corresponding accessories, the devices can also be used in areas where temperature is low. The smoke aspirating system is able to detect even the smallest glowing and smouldering fires and can be deployed more or less anywhere. The system consists of one or two independent aspirating lines including sampling points and a highly sensitive smoke sensor. Using an airflow monitoring process, the aspirating line is permanently monitored for pipe breaks and contamination of the aspirating apertures.
