摘要
A wall-type intercom station for detention and penitentiary facilities is disclosed. The station is comprised of a flush mounting box (2') which is formed of a plurality of profile elements (21, 24, 25) that are structured as extruded profiles. The profile (21) is generally C- shaped and forms a bottom wall, top wall, and back wall of the box (2'). Profiles (24, 25) form side walls of the box (2'). A ring (26) is received about the perimeter of the profiles (21, 24, 25) and is received within slots (40, 42, 44, 46) formed along the front edge of the profile elements. Pushbutton switches (15) and lights (16) are secured to a cover plate (5) within jar-like containers filled with pressed glass (31).
