Combo Access Control

Compact single-relay access controllers that combine two or more authentication methods in a single unit — RFID card, PIN code, fingerprint, or remote WiFi control via the Tuya Smart app. Designed for installations that need flexible per-user authentication without the complexity of multi-relay floor-by-floor wiring. Single-relay output supports three standard lift topologies: main supply cut-off, single-floor restriction (wired in series with one cabin call button), or landing call control (installed at the floor to prevent unauthorized lift calls). For multi-floor selective access with up to 8 relays, see our NFC Card Reader or iButton systems or Keylock with Password
