Earliest Fire Detection system (ASD) – Air sampling smoke detection systems are smoke detectors that actively pull air samples from the monitored area and analyse them for the presence of smoke particles. They basically consist of a detection unit and the associated pipe system. The low pressure needed for air sampling is produced by a fan. Air flow sensor technology ensures functionality by constantly monitoring the pipe system for breakages and obstructions. More Info
