The i-KP01 is a wired keypad with large LCD display and built-in dedicated, compliant HUA function and proximity reader. Navigation and text input is a similar user experience to mobile phones, enabling the installer and user to scroll through easy to follow menus. The radio option, the i-RK01, is powered by three alkaline AA batteries, or can be attached to an external DC power supply. Designed to be an additional keypad, the radio feature means it can be flexible in its location. No display provides simple set and unset.
