FB1000 is a single-lane flap barrier consisting of a master-device and a slave-device to form an entrance.
Flap Barriers are well adopted in entrances and exits of buildings or construction sites, to help tracking staffs and visitors. Only authorized users are able to access to specific areas through the flap barriers. Lights on the barriers are to indicate status of the flap barriers. Steady green lights indicate locked barriers. Blinking green lights indicate accessible barriers.
