As the deflection is at right angles to the direction of travel there is no reverse thrust from the door. The door is fitted with rows of tin plated beryllium copper contact strips around its periphery. The P.C.S. doors are equipped with our two point latching system to provide positive closure. The latching system has been tested in excess of 250,000 trouble free operations. Bearing surfaces, rollers and door cams are of case hardened steel, designed to provide years of trouble free operation with no loss of attenuation due to friction and wear.
Ball bearing adjustable hinges complete the fitting of the door.
Special door features include electromechanical door interlocks, alarm systems, waveguide vents and window inserts. The walls, floor and ceiling panels are of the same construction. Each panel is nominally 2.4m by 1.2m. The panels are joined and supported by specially designed members that clamp the edges of the panels and provide continuous, uniform and constant pressure contact against the shielding elements of the panels. The walls are self supporting from floor to ceiling with no bracing against the parent room construction.
