Wired Keypad with RFID Paradox K-641/R – access control keypad, wired connection, RFID support

Paradox K-641/R is a wired access control keypad with integrated RFID reader designed for wall-mounted installation in residential and commercial security systems. The unit provides a tactile keypad for numeric code entry, basic system commands for arming and disarming, and proximity tag recognition via RFID. Its wired connection ensures continuous communication with the control panel and reliable operation for everyday access management and alarm system control.

Advantages

The wired design offers stable, low-latency communication with security panels and reduces the need for battery changes. Integrated RFID support allows fast, contactless user authentication while the numeric keypad supports traditional PIN entry and system commands. The compact form factor and wall-mount configuration simplify installation in entryways, service rooms, and access-controlled points. Materials and layout are optimized for frequent daily use and clear tactile feedback.

How to use

Install the keypad on a stable wall surface near the intended entry point and connect it to the security control panel following the panel manufacturer’s wiring diagram. Configure user codes and register RFID tags through the control panel interface or management software so that authorized users are recognized by either PIN or RFID. Use the numeric keypad to enter codes and system commands; present an authorized RFID tag near the reader area for contactless access. Regularly verify communication status and user lists in the control panel to maintain correct access permissions.

Usage recommendations

Place the keypad at a convenient height for users and away from direct weather exposure; for outdoor installations, use a weather-protective enclosure. Periodically test both PIN and RFID authentication and review access logs on the control panel. Ensure wiring is secured and follows local electrical and security installation standards to maintain reliable operation.
