Breakout Doors

The ZAMTAS NG BOS automatic door system has created easy access for areas in a variety of venues that require access for large portable objects, and allows for maximum fire egress.

The NG BOS system not only makes access easy but allows for productive traffic flow when large crowds are accessing specific areas. The system complies with the Australian building code and is a valuable development in automatic doors.
