ERRC & BDA Systems

Firefighters need their radios to work inside your building. We make sure they do.

Fire code requires it. Concrete and steel block the signal. We test your building and install the system that fixes it — a BDA, also called an ERRC system.

  • Testing that tells you exactly where you stand
  • Design and installation by our own crew
  • Yearly testing after, so you stay compliant

How it works

1. What the code requires

Emergency responders have to be able to use their radios everywhere in the building. Your fire official checks it before signing off.

2. Why most buildings need help

Concrete, steel, coated glass and below-grade levels all block radio signal. Modern construction is particularly good at it.

3. How it gets solved

A rooftop antenna picks up the signal, an amplifier boosts it, and antennas carry it through the building. You’ll see it called a BDA or an ERRC system.

No radio coverage, no certificate of occupancy.

It is one of the few things that can hold a finished building empty. We test before your inspection is booked, and fix whatever the test finds.
What your building is measured on

The six things an inspector checks

95%Coverage Radios must work in 95% of the building — and 99% of stairwells, lobbies and fire command rooms.
ClearSound quality Speech has to be understandable, not just audible.
−95 dBmSignal strength The weakest signal the code will accept anywhere in the building.
12 hrsBackup power The system has to keep running through a power cut.
ApprovedEquipment Only certified public safety gear passes inspection.
YearlyRe-testing Required every year, and it is the building owner’s responsibility.
Signal strength scale showing the code minimum A scale from minus 120 to minus 70 dBm. Anything weaker than minus 95 dBm is below code; minus 95 dBm and stronger meets it. TOO WEAK MEETS CODE -120 -110 -100 -90 -80 -70 -95 dBm MINIMUM

The exact rules depend on the code edition your town has adopted — usually IFC 510 and NFPA 1225. We check that for you before anything is designed. Your local fire official has the final say.

Step one

It starts with a test

We walk your building on a grid and measure the radio signal at every point, then hand you a report your fire official will accept. It is the only way to know where you stand.

Already compliant? You’re done

You get the report and help closing it out. No system, no equipment, nothing sold.

Not yet? We make sure you pass

The test shows exactly which areas are short. We design and install a system to cover them, and stay on it until your building is signed off.

  • Your inspection is coming up and nobody has tested the radio signal.
  • Your building didn’t pass, or your paperwork came back rejected.
  • You have a system already and it’s showing a fault or has stopped working.
  • Your yearly test is overdue, or you’re budgeting a new build.
What we do

Five things, done by our own people

Testing

We measure the radio signal throughout your building and give you a report you can submit.

Design

Our engineers design the system and our own architect stamps the drawings.

Installation

Our technicians install everything — antennas, cabling, amplifier and backup power.

Certification

We test the finished system and hand over the paperwork your fire official needs.

Yearly testing & repairs

Annual testing, battery changes and repairs, so your system stays compliant.

Fixing other people’s work

Systems that didn’t pass, or that another contractor started and walked away from.

What working with us looks like

Four steps, one team

01

You call

Tell us about the building. We tell you what your town requires.

02

We test

We measure the signal throughout and give you a straight answer.

03

We build

If you need a system, we design it and our crew installs it.

04

We certify

Final testing, your paperwork, then yearly testing after that.

Why choose us

Six reasons owners pick us over the other guy

It’s all we do

Fourteen years on emergency radio systems only. Most competitors do this on the side between alarm and cabling jobs.

One crew, no subcontractors

The people who test your building are the people who design and install the system. Nothing gets lost in a hand-off.

We’ll tell you if you don’t need us

If your building already passes, we say so and hand you the report. We don’t sell systems buildings don’t need.

Drawings stamped in house

Our own architect stamps the plans, so you aren’t waiting weeks for an outside engineer to fit you in.

We take the hard jobs

Buildings that didn’t pass and systems others gave up on. We tell you what it takes and hold that price.

We’re still here next year

We do your yearly testing and keep your records straight, so compliance doesn’t quietly lapse after handover.

Common questions

Questions we get every week

You test it. We measure the radio signal throughout the building and give you a straight answer. If it already passes, you get the report and install nothing. If it doesn’t, the same test tells us exactly what the building needs.

An antenna on the roof picks up the emergency radio signal from outside, an amplifier boosts it, and antennas around the building spread it to every floor. You’ll see it called a BDA, an ERRC system or a public safety DAS — they all mean the same thing.

It depends on the size of the building, how many floors need covering, and how strong the outside signal is. Anyone giving you a firm price before testing is guessing. We price it once the test tells us what’s needed — and if you pass, there’s nothing to buy.

In most towns, yes. Radio coverage is usually checked before final sign-off, so a missing or failed test can hold up your CO. That’s why it’s worth testing early rather than the week of your inspection.

Testing and a report usually take a few days. If a system is needed, design comes next, then installation — a few days on a mid-size building, longer on a large or occupied one — and then final testing. Starting early keeps it off your critical path.

Yes, and it’s the building owner’s responsibility, not the installer’s. We do the yearly test, replace batteries when they’re due, and keep the records ready for your fire official.
