Door Controllers
February 14, 2002
Radionics introduces the new K2200 (four-door) and K1200 (two-door) door controllers. These multi-function door controllers can operate as stand-alone, local, remote master or slave units. Each door controller, with the addition of readers and locks, provides a fully functioning access control system. The two systems have full alphanumeric keypad and 16-character displays.
