About this file

This document is a specification for a fire detection and alarm system for the Robley Rex VA Medical Center in Louisville, Kentucky. The specification requires extending the existing fire alarm system by installing new devices and connecting them to nearby existing fire alarm circuits. New conduit, wiring, notification appliances including strobes, and fire alarm panels must meet NFPA and NEC standards. The contractor must provide as-built drawings, manuals, testing, training and a one year warranty. The related federal contract opportunity is for safety improvements to the Ambulatory Surgical Unit Post-Anesthesia Care Unit (ASU PACU) at the same Robley Rex VA Medical Center, with the Department of Veterans Affairs as the contracting agency.
