The DOORBIRD 423864375 is a replacement doorbell panel designed for use with the D21X series video door station. This panel provides the front-facing bell button interface that connects to compatible D21X intercom units in residential and light commercial access control installations. It ships as a single unit and is finished in RAL1001 (Beige) to match coordinated facade installations. Licensed low-voltage or access control technicians typically handle installation as part of a door station assembly or repair workflow.
This panel is suited for properties where the D21X door station is already installed and the bell panel component requires replacement due to damage, finish preference, or upgrade. The RAL1001 color finish makes it appropriate for installations where a beige or warm neutral exterior tone is specified. It is classified as an intercom accessory and is sold as a single unit.
Designed for use with the DOORBIRD D21X series door station as a replacement bell panel component.
Installation should be performed by a licensed low-voltage or access control technician familiar with door station intercom systems. Disconnect power to the door station before removing or installing any panel components. Follow the manufacturer's wiring documentation and applicable local low-voltage codes during reassembly. Do not force panel connectors or modify mounting hardware during fitment.
