1. What Is ERRC and Why Does It Matter?
ERRC (also referred to as public safety DAS, two-way radio systems, or emergency radio enhancement systems) exists for one reason: to ensure first responders can communicate inside a building during an emergency.
As Brian explains, the modern push for ERRC traces directly back to the events of September 11, when communication failures inside high-rise buildings had tragic consequences. Since then, codes have evolved to ensure firefighters, police, and emergency personnel can communicate:
2. ERRC vs. DAS vs. “Whatever My City Calls It”
One of the biggest challenges with ERRC? The naming confusion.
While the International Fire Code refers to ERRC specifically, many owners and project teams use the umbrella term DAS (Distributed Antenna System), which can also mean cellular DAS (a non-required, luxury system).
Understanding the distinction early can prevent costly misunderstandings later in design and construction.
3. Is ERRC Required in Every Building?
This is one of the most common misconceptions.
The code does not say “every building must install ERRC.” Instead, it requires:
If a building fails signal testing, ERRC becomes the solution.
4. How Codes Intersect: IFC, NFPA 72, and NFPA 1221/1225
ERRC design doesn’t live in a single code book.
Over time, these codes have become more aligned but navigating them still requires experience.
5. Backbone Survivability: Where Design, Cost, and Coordination Collide
One of the most misunderstood (and expensive) aspects of ERRC is backbone survivability, how long system cabling must survive during a fire.
As Brian explains, early coordination is everything.
6. Three Levels of ERRC Design Services (And Why Option B Wins)
JSE approaches ERRC with flexibility, offering three levels of service depending on project risk, size, and certainty:
What This Means for Developers, Architects, and Engineers
ERRC is no longer an edge-case requirement; it’s a project-defining life-safety consideration that can impact:
At Jordan & Skala Engineers, our integrated MEP, Sustainability, and Low Voltage teams help clients navigate ERRC early so there are no surprises late.
