The IKB-12P is a single-channel digital partyline intercom station that has 12 call buttons, a loud alert buzzer, and a rotary knob for controlling volume and menu navigation. Using a HelixNet HMS-4X main station and the browser-based software configuration tool, up to 64 IKB-12P intercom stations can be individually controlled and configured using an Ethernet connection. Each call button can be assigned a profile to determine that button’s functionality. If more call buttons are required, an additional 28 can be added via a custom expansion panel for a total of 40 call buttons. An IKB-12P can be wall-mounted or placed in a dedicated desktop unit.
