- Description
The Paradox K641RPLUS-N3Q (K641R+) is an advanced, hardwired 32-character blue LCD keypad module featuring an integrated 125 kHz proximity card reader. Specifically engineered for Paradox Digiplex EVO control panels (such as EVO192 and EVOHD+), it seamlessly combines intrusion alarm system management with local access control into a single elegant interface. Users can arm or disarm system partitions, unlock doors, or trigger automation routines simply by presenting an authorized proximity card or entering a valid user PIN code.
Designed with a high-visibility backlit blue LCD display, the K641RPLUS supports customizable zone, partition, and user labels for intuitive navigation and status monitoring. It provides real-time zone alarm displays, 14 one-touch function keys, and 3 keypad-activated panic alarms. Additionally, the keypad features 1 on-board addressable zone input and 1 PGM output, simplifying installation by accommodating a local contact or door contact directly at the keypad location.
