The ATRIUM A22K two door IP controller works perfectly with the most popular Wiegand card readers or with the embedded KRYPTO high-security solution, providing the best of both worlds in access control. KRYPTO is the easiest solution to manage DESFire EV2/EV3 smart credentials on the market making worries of card cloning a thing of the past. The auto restore of encryption keys upon power failure ensures an effortless system start up and management. Additionally, the A22K can easily be converted to an elevator controller (A22KEC), Schlage door handle controller (ADH2K), or Aperio door handle controller (A2PK) as needed. ATRIUM’s efficiency will simplify your life.
