Attachment V - Existing Overhead Page Audio Groups - Dial Code Matrix.xlsx

This file is a dial code matrix reference document for an existing overhead paging system at a Veterans Affairs medical facility. The spreadsheet lists 3-digit dial codes (accessed by dialing *64 plus the code) that correspond to specific audio groups and locations throughout the facility's multiple buildings and departments.

The document maps approximately 100 dial codes to various hospital areas including patient care units (ICU/CCU, nursing stations by floor), clinical departments (Cardiology, Pulmonary, Neurology, Radiology, Pharmacy, Dialysis), administrative areas (director offices, conference rooms), and facility-wide announcement groups. Notable codes include: codes 100-339 for individual building and departmental zones; codes 450-460 representing multi-building groups; code 777 designated as "KILL ABSOLUTE" (emergency all-stop function); code 888 for "ALL CALL - ALL BLDGS"; code 890 for building-wide calls excluding patient areas; and code 911 for emergency boost to key buildings (310, 315, 321, 330, 340). This matrix serves as the configuration reference for the existing paging infrastructure that will be replaced under Project No. 552-26-202, as indicated by the related solicitation.
