Radio Key® 600 is a compact, weather-resistant, surface mounted Access Control Unit, which has a built-in programmer. Because it has an internal reader, it can stand alone for most applications. Secura Key's patented DYNASCAN®* technology assures maximum performance in any environment. The optional Auxiliary Reader can be used with Radio Key® 600 to provide extraordinary protection against weather and vandalism. Entry cannot be obtained by tampering when the Auxiliary Reader is mounted outside. For further protection, both the Access Control Unit and Auxiliary Reader can be mounted behind glass or other non-metallic wall surfaces. When installed with the Auxiliary Reader, the Access Control Unit can be used as an exit reader and as an enrollment reader. Either unit easily mounts to a single-gang electrical box, masonry wall, post, or almost any surface -- there are no bulky control panels to install. To use Radio Key® 600, simply hold your key tag near the Access Control Unit or optional Auxiliary Reader or enter your PIN code into the keypad. Programming is easily accomplished by using the built-in keypad. Key tags can be added by holding each key tag near the unit or by using the keypad, without the tags being present. The keypad is also used to void tags, set the latch time and to select the active, inactive or unlocked modes. The optional RKAT Audit Trail Module allows connection to a PC or serial printer. Software included provides reports on transaction history, allows programming of key tags or PINs, user name database and other reader settings. RK-LINK™ Software also allows RK600 memory to be backed up and restored. Power supply ST-RKPS is not included. Cards or tags not included. Auxiliary reader (without keypad) available for second door, Order #ST-RK600E. See options above.
