Edwards EST 4X-DR Blank Fire Alarm Annunciator Filler is a dedicated blank module for the 4X-DR fire alarm annunciator series, designed to occupy an unused annunciator position on Edwards fire alarm panels. Identified by the model designation 4X-DR, this industrial filler provides a proper faceplate for empty slots in the Edwards annunciator lineup. Use of this blank filler helps maintain a consistent panel appearance when an annunciator channel is not installed.
