Wagner UK has produced a handy guide to Aspirating Smoke Detection (ASD), which is available free of charge, directly from the company. An invaluable guide for consultants, fire system designers and installers, the 20-page A5 booklet covers areas such as an introduction to ASD technology, European standards, designing and installing ASD systems, applications and an overview of ASD products.
Wagner UK has been at the forefront of ASD development for a number of years and has produced this guide in response to the significant changes heralded by a new European Standard. EN54 Part 20 is the European product standard for Aspirating Smoke Detectors, which has changed the way aspirating systems have to be designed and installed.
ASD systems draw air samples continuously from the monitored area through a series of pipes fitted with sampling holes at regular intervals. The airflow is then analysed for smoke particles and an alarm is raised if smoke is present. The system is active, continually drawing air samples from the risk areas which enable ASD systems to detect fires at a very early stage.
