What to do if ZKTeco TS1011 Pro do not grant access after authentication?
- TTyler RosalesAug 12, 2025
If a ZKTeco turnstile doesn't grant access after successful authentication, here's what to check: 1. Verify the user has the necessary permissions. 2. Use a multimeter to check the NO and COM ports of the access control system for a relay signal output. 3. Short-circuit the ports "K1, GND" and "K2, GND"; if the turnstile opens, inspect the access controller.
