The MPR series is designed to control pedestrians entering or exiting restricted areas, usually under surveillance, in low security situations. Personal surveillance is therefore recommended as the barrier can be breached. The aisle is blocked by means of a retractable triangular wing made of an aluminum core construction covered by PU-foam. Alternatively an acrylic glass wing is available. Two different models allow two different passage widths (520mm and 960 – 990mm). The MPR series can be used in bidirectional applications to control the entry and exit with only one line. A line or installation consists of at least two modules.
