Critical Communications — IFC 510

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

The International Fire Code (Section 510) requires approved in-building radio coverage for emergency responders in all new buildings, and many Utah jurisdictions apply it to existing buildings. Where the signal inside falls below the required minimum, an Emergency Responder Radio Coverage System (ERRCS) — a bi-directional amplifier (BDA) and distributed antenna system (DAS) — must be installed. 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 a common source of late-stage inspection delays. 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.

PCS installs Nextivity and Potter ERRCS/BDA/DAS systems and works within both manufacturers' licensing programs. We conduct the required in-building radio frequency surveys, design the system to meet minimum signal strength thresholds, and work with the AHJ and the public-safety radio system licensee to obtain the required approvals, while our NICET IV-led fire alarm team handles the supervisory tie-in to the fire alarm panel. 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.

Nextivity & Potter Systems

We install Nextivity and Potter ERRCS/BDA systems within both manufacturers' licensing programs, and our NICET IV-led fire alarm team handles the supervisory tie-in to the fire alarm panel.

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 approved in-building radio coverage in all new buildings, and many Utah jurisdictions apply it to existing buildings. Where a signal test shows coverage below the required minimum, an ERRCS must be installed. 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 (carrier) 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.

Timing depends on building size and complexity, how complete the architectural drawings are, and coordination with other trades. Smaller projects can move quickly, while complex multi-trade projects take more back-and-forth. PCS sets a schedule at kickoff, coordinates with the general contractor to fit the ERRCS installation into the broader project schedule, and keeps the AHJ submittal moving.

Under the International Fire Code (Section 510.6.1), the building owner must have the ERRCS inspected and tested every year, and again after additions, remodels or structural changes that could affect coverage. PCS provides annual ERRCS testing programs and produces the documentation your AHJ requires.

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.
