The Laser-SCANNER locates the origin of smoke by identifying the first sector (pipe) with the highest level of smoke and then continues to sample from all sectors to monitor fire growth. The LaserSCANNER also provides four alarm levels for each individual pipe (Alert, Action, Fire 1 and Fire 2) and provides individual pipe addressability and individual pipe settings. It protects areas up to 20,000 sq.ft./5000 sq.ft per sector (2000 sq.m/500 sq.m per sector).
