Critical Communications — IFC Chapter 5

ERRCS
/ Distributed Antenna Systems

In-building first responder radio coverage systems — IFC-compliant ERRCS and DAS design and installation across Utah jurisdictions.

Overview

First Responder Radio Coverage — Done Right

Emergency Responder Radio Coverage Systems (ERRCS) — also called Bi-Directional Amplifier (BDA) or Distributed Antenna Systems (DAS) — are required by the International Fire Code (IFC) Chapter 5 in most new construction and many existing buildings in Utah. These systems ensure that first responders (police, fire, EMS) can communicate reliably within your building using their radio systems during an emergency.

ERRCS is one of the most misunderstood life safety requirements in Utah — and one of the most frequently cited code deficiencies on new building inspections. PCS has deep expertise in ERRCS design and installation, and maintains current working knowledge of each Utah jurisdiction's specific frequency requirements and signal strength standards.

Our NICET IV engineers conduct the required in-building radio frequency surveys, design the system to meet minimum signal strength thresholds, and work with the AHJ and local public safety answering points (PSAP) to obtain the required approvals. We manage the entire process from initial survey through final acceptance testing.

Why Choose PCS

The PCS Difference

Utah Jurisdiction Expertise

Each Utah jurisdiction has specific frequency requirements. PCS knows the current requirements for Salt Lake City, Sandy, West Jordan, Provo, and surrounding AHJs.

NICET IV System Design

Our NICET IV engineers design ERRCS systems — ensuring the RF survey, system design, and documentation meet IFC and AHJ requirements the first time.

Full Documentation Package

PCS produces the complete documentation package required by Utah AHJs: RF survey results, system design, equipment submittals, and acceptance test reports.

End-to-End Installation

From the donor antenna on the roof to the last DAS antenna on the lowest floor — PCS manages every aspect of the ERRCS installation.

FAQ

Frequently Asked Questions

ERRCS (Emergency Responder Radio Coverage System) ensures that first responders can communicate using their public safety radios inside your building. IFC Section 510 requires ERRCS in most new buildings and in existing buildings that cannot demonstrate adequate radio coverage. Requirements vary by jurisdiction — PCS can conduct a signal strength assessment to determine if your building is compliant.

ERRCS is specifically designed for public safety (first responder) radio frequencies and is a life safety code requirement. Commercial DAS enhances cellular and Wi-Fi coverage for building occupants. The two systems use similar technology but are designed for different frequency bands and have different regulatory requirements. PCS specializes in ERRCS/public safety DAS.

Timeline depends on building size and complexity. A typical commercial building of 100,000 square feet might require 2-4 weeks for installation after the design and permitting phase. PCS coordinates with the general contractor to fit the ERRCS installation into the broader project schedule.

IFC 510.4.1 requires annual inspection and testing of ERRCS systems by a qualified individual. PCS provides annual ERRCS testing programs, producing the documentation required to maintain compliance with your local AHJ.

Yes. Many existing buildings in Utah are being retrofitted with ERRCS as jurisdictions enforce code requirements on existing buildings. PCS conducts baseline signal surveys, designs the system, and manages the installation and approval process for retrofits.
