Dormakaba Multihousing R21220 InSync SAM RF Encoder – Power Cord NOT Included

The R21220 is the encoder base station that makes all of that work. It's the hardware that sits at the management office, connects to the PC running SAM RF software, and programs every key credential in the system. New resident moves in: a key is encoded on the R21220. Resident moves out: that key is deactivated on the R21220. Resident loses a key: the lost key is deleted and a new one encoded, without re-programming the lock.

The R21220 includes extra memory over the standard encoder, allowing more data storage on the unit for larger property deployments. Power cord is not included and must be sourced separately. The Handheld Utility Device is also not included but is available as a separate component for field programming without returning to the management office. Ships within 4-6 weeks as a special-order item. For all Dormakaba electronic access control hardware, browse our keypad and prox locks catalog.

How the InSync SAM RF System Works

The InSync system distributes access control information through the key itself, not through a network or panel. When a property administrator programs a new key using the R21220 encoder and SAM RF software, that key carries the programming data. The first time the new key is used in an InSync lock, the lock updates its own access list. This "sneaker net" approach means the locks don't need to be connected to a network or wired to a central controller. Programming reaches each lock as residents enter, automatically.

When a resident moves out, their key is deactivated in the SAM RF software. The next time any valid key (typically the new resident's key or a master key) is used in that lock, the deactivated key is removed from the lock's recognition list. The R21220 is the critical hardware that initiates every one of these credential transactions.

InSync Credential Technology

InSync keys use HiTag RFID as the base technology. Dual Technology keys add a second chip (MIFARE or DESFire) to the same credential, which allows the single InSync key to also work at common area RFID readers that use MIFARE or DESFire rather than HiTag. This means a resident can use one key for their unit door (HiTag via InSync lock), the building's access control gate reader (MIFARE via the gate reader), and any other reader in the building, without carrying multiple credentials.
