ACRE K44 Keypad | L8633

The K44 Duo is a programmable standalone keypad for controlling access through one or two doors. It can operate each door using separate PIN codes or allow the same code to release both doors, making it suitable for a range of single-door and two-door access control systems.

The keypad stores up to 30 user codes, consisting of 20 four-digit codes and 10 six-digit codes. Two relay outputs, adjustable door-open times and a two-door interlock function provide installers with additional flexibility. Codes and settings are retained in non-volatile memory during a loss of power.
