Doorbird 423864252 Intercom Blank Panel RAL7023

Product Description

The DOORBIRD 423864252 is a blank panel module designed for use with the D21X modular door station intercom system. This panel fills unused module slots in a D21X intercom assembly, maintaining a clean, finished appearance on the faceplate while keeping the enclosure sealed against dust and debris. Finished in RAL7023 Gravel Gray, it matches the standard color family of the D21X product line. Installation is performed by security integrators, low-voltage technicians, or access control specialists configuring modular door station layouts for residential or commercial entryways.

This blank panel is used when a D21X door station is configured with fewer functional modules than the total available slots. Rather than leaving a slot open, the blank panel maintains the integrity of the faceplate assembly. It is appropriate for both flush-mount and surface-mount D21X installations. The RAL7023 finish ensures a consistent appearance across mixed-module configurations on the same door station unit.

Installation Notes

Low-voltage technicians and access control installers typically handle D21X module configuration. Before adding or swapping any module in a door station, power down the unit at the source to avoid damage to internal electronics. Follow the manufacturer documentation for proper module seating and retention in the D21X frame. Local low-voltage and access control codes may apply depending on jurisdiction.
