Choose the mounting and input format

KR901 and KR902 use the narrow mounting format; KR902 adds a keypad. The corresponding S models use the wider single-gang/European-box format. KR903 and KR904 use the square Asian-box format, with a keypad on KR904.

Match the controller communication

The Wiegand-only listings document W34/W66 output. The RS485 listings require the appropriate receiving implementation. Current manufacturer evidence names ZKTeco RS485; OSDP claims in supplier information remain unverified and must not be assumed from the presence of RS485 wiring.

Category FAQs

Does a keypad model decide access permissions by itself?

No. The reader provides credential or keypad data to the compatible receiving system. The controller and its configuration determine the permitted authentication and door-control workflow.
