Does my Texas building need ERCES / BDA?

Under the 2024 International Fire Code §510, every new building must pass a public-safety-radio coverage test at acceptance. Many existing buildings also trigger scope after occupancy changes or code adoption. Run the free Building Signal Check to see if your specific address falls under an AHJ that has adopted the trigger, and what the local amendments say.

What does an ERCES / BDA installation cost in Texas?

A typical 40,000 sq-ft Class-A office in DFW that fails initial survey runs $35,000–$65,000 turnkey. Larger buildings, high-rise, or concrete construction can exceed that. The variables are building size, construction type, donor signal strength, coverage grid density, and AHJ requirements.

How often does an ERCES system need to be retested?

IFC §510.6 requires an annual functional test, full re-survey after significant RF-environment changes, and typically a 5-year full recertification per most Texas AHJs. Zion delivers a scheduled recurring survey, AHJ report filing, and remediation if signal drifts.

Is Zion an authorized dealer for RSI and Honeywell/Fiplex?

Yes. Zion is an authorized dealer for RSI and Honeywell/Fiplex ERCES / BDA amplifiers — the two most widely accepted UL 2524 platforms in Texas. We're also iBwave-certified for BDA / DAS design.

ERCES and BDA installation in Texas — done right, the first time.

If your Texas building falls under IFC §510, first-responder radios have to work inside every corner of it. We design, install, test, and re-certify the ERCES / BDA systems that make that happen — across 691 cities in 13 U.S. states — 291 of them in Texas alone, and expanding — backed by RSI and Honeywell/Fiplex authorization. Not sure if you're in scope? Our Building Signal Check tells you in 60 seconds.

Building Signal Check™ — free 60-second ERCES scoping for Texas building owners. Backed by 291 Texas AHJs and Zion's licensed BDA division.

Building Signal Check — the tool

Four questions about your building: size, height, jurisdiction, and current radio coverage. Sixty seconds. We return a clear answer on whether you're in IFC §510 / NFPA 1225 scope, what your AHJ has adopted, and what the next step looks like.

Backed by 291 Texas AHJs (part of Building Signal Check's 691-city, 13-state footprint — constantly expanding) — the same data we use internally for permit submittals.

When ERCES applies to you

Generally any of the following puts a building in IFC §510 scope:

New construction over 50,000 ft² (varies by AHJ; some Texas AHJs use 25,000 ft²)
Buildings four or more stories
Below-grade space over 25% of floor area
Substantial renovation that triggers AHJ re-review
Buildings already with BDA that need annual testing

The Building Signal Check walks you through it in under a minute.

What grid-square testing looks like

Joel Sadowsky conducting an NFPA 1225 grid-square signal survey inside a Texas warehouse — testing public-safety radio coverage bay by bay — NFPA 1225 acceptance and annual testing requires signal-strength measurements taken at the center of every 40×40 ft (1,600 ft²) grid square throughout the building — plus 100% coverage in critical areas (stairwells, fire pump rooms, fire command centers).

Pass criteria are stricter than most owners expect: −95 dBm or stronger in 95% of general-occupancy grid squares, 100% in critical areas, and FCC-licensed donor signal validation. We've walked these surveys across 100+ Texas buildings. The data goes into a written report your AHJ accepts.

Answers to the two questions owners always ask

How much does BDA / ERCES cost in Texas? →

Real turnkey ranges. Typical 40,000 sq-ft DFW office that fails initial survey: $35,000–$65,000. What drives the number, what's free vs. paid, how to lock in a fixed price.

How often does it need to be tested? →

IFC §510.6 requires an annual functional test, plus a 5-year full recertification. We take that off your calendar and file directly with your AHJ.
