Find out whether your property passes the signal test

Where a jurisdiction enforces ERRCS, the AHJ requires public safety radio coverage to be measured and to pass before the property is signed off. A certified LINX engineer walks the property, heat-maps every carrier and the public safety band, and tells you plainly what you need, including when you need nothing at all.

  • Grid-walked heat map per carrier and per public safety frequency
  • Written results with pass/fail against the code your AHJ enforces
  • Many tested properties need less system than they were quoted elsewhere
  • Where an ERRCS applies, the AHJ requires a signal test and the property has to pass it before sign-off

HOW IT WORKS

From request to results in one visit

STEP 01
Tell us the address

Four fields. We confirm coverage in your region and call you back the same business day.

STEP 02
We walk the property

One engineer, calibrated scanners, a grid walk of every level including garages and stairwells.

STEP 03
You get the heat map

Per-carrier and public safety results, marked pass or fail against the threshold your AHJ enforces.

STEP 04
Then decide

A budgetary design if you need a system. An honest no if you do not. No obligation either way.

EVERY SCOPE, ONE CONTRACT

Design, install, test and support, all under one contract.

One point of contact for design, installation and long-term support, instead of handing your property between four companies.

SYSTEM DESIGN

Engineers evaluate the property and design a system that maximizes coverage and minimizes cost.

Technician installing wiring
INSTALLATION

Our crews deploy, commission and manage the project start to finish.

TESTING

We heat-map the property, identify deficient areas per carrier and document the results.

Team reviewing plans on site
CONSULTING

We help you choose the right solution, with design concepts and budgetary guides.

CODE & COMPLIANCE

Your approvals depend on this system passing.

Many state and local codes require a public safety ERRCS, and requirements differ from one jurisdiction to the next. We design to the code your AHJ actually enforces, handle the paperwork, and test the finished system so you have a report to hand them.

  • Designed to your AHJ’s adopted code edition, not a generic national reading
  • Permit drawings, submittals and stamped documentation handled for you
  • We run the test and give you a report to submit to your AHJ
  • Annual inspection and monitoring requirements documented up front

QUESTIONS WE GET

Is an ERRCS actually required for my property?

Many jurisdictions now require a public safety radio system as a condition of occupancy or final sign-off. Whether it applies to your property, what triggers it, and how strictly it is enforced all vary by AHJ, which is why we design to your local code rather than a national assumption.

What is the difference between an ERRCS and a cellular DAS?

An ERRCS carries first responder radio traffic and is code-driven. A cellular DAS carries commercial carrier signal and is amenity- and operations-driven. A converged system uses the same cabling and antennas for both, which is usually the cheapest way to end up with both.

Do you use subcontractors?

Design, installation, testing and consulting are self-performed by our own teams. That is why schedule commitments hold, and why there is one company to call when something needs attention.

How long does an installation take?

It depends on size and construction, but the design and permitting path is usually the long pole, not the install. We give you a real sequence of work with the quote so you can plan against it.

We failed our acceptance test. Can you help?

Yes, and it is a common call. We test independently, identify why it failed against the code threshold, and give you the shortest path to passing rather than a proposal to start over.
