May 25, 2010 Using sequential blanking algorithm, BFD Series can distinguish between door closing and object or person in door opening. When door area is clear, closing door will block beams in pre-determined sequence, and will not trigger alarm signal. If person or object breaks beam, alarm output is immediately sent, which can stop or reverse door, or prevent it from closing. Designed for door openings up to 12 m wide, BFD Series comes in 6.5 and 8.2 ft heights with NO or NC selectable outputs.
