MT™ is a multi-technology locking system. The non-volatile FLASH circuitry stores up to 5,900 entries to provide detailed audit-trail information, such as date and time of the entry as well as the ID code of the employee or guest using the keycard. The MT™ lock is easy to use and works with the Windows-based System 6000™ and DeskLinc™ front desk systems. A mechanical key override (MKO®) feature is also available.
