FAQ

What card readers, locking devices, and network protocols are compatible with the C3-200 controller?

Answer:
The C3-200 supports standard 26-bit Wiegand (with other formats upon request) and RS-485 readers, fail-safe or fail-secure locks via Form-C dry contact relays, and integrates over TCP/IP, RS-485, and optional Wi-Fi networks.

The C3-200 offers broad hardware compatibility across standard electronic security peripherals:

  • Reader Protocols: Connects to industry-standard 26-bit Wiegand devices (RFID proximity, smart card, PIN keypad, and barcode/QR scanners; other Wiegand bit formats upon request) as well as multi-drop RS-485 digital slave readers.
  • Locking Devices: Interfaces directly with fail-safe (power-to-lock, such as magnetic locks) and fail-secure (power-to-unlock, such as electric door strikes and motorized drop bolts) locking systems via onboard Form-C relay contacts.
  • Door Sensors & Exit Hardware: Connects directly to standard dry-contact request-to-exit (REX) buttons, key switches, and magnetic door reed switches.
  • Host Communication: Communicates with access control software over standard IEEE 802.3 TCP/IP Ethernet local area networks, long-distance EIA/TIA RS-485 serial buses, and optional Wi-Fi interfaces.
