NIH Building 10 complex fire alarm system upgrade

  • Duration: July 2017 - April 2019

  • Location: National Institutes of Health (NIH), Bethesda, MD

  • Contract Value: $6,146,830

As the base contract is complete, this innovative fire alarm system upgrade, included the largest, which is currently in operation. This system is the first of its kind and offers selective paging to approximately 500 different speakers zone and replaced 100 existing fire alarm system panels.

Five (5) new workstations and interconnecting fiber runs were installed between several NIH buildings on the campus.

A major challenge was the existing system node XLS panels with fire alarm devices, which exceeded the system node XLS panel limitation for a single global voice system. We overcame this obstacle by consolidating 75 panels to 52, including deleting panels, relocating field circuits to alternate panel locations, and modifying electrical circuitry locations.

The project included fire alarm, electrical, and fiber optic work.
