Find and Hire an ERCES Installer

How to hire an ERCES contractor

Whether you use our referral or find a firm on your own, the same checks apply. This is what to look for, what to ask, and what a complete quote should cover.

What the job actually involves

Most ERCES projects run in the same order, and some firms only handle part of it:

1. RF survey / grid test of existing coverage — see ERCES testing & surveys.
2. Design and submittal to the fire department (AHJ), including coordinating with the public safety agencies whose frequencies the system will rebroadcast — see design & planning.
3. Installation of the signal booster (BDA), antennas, and cabling — see installation and BDA vs DAS.
4. Acceptance testing and commissioning witnessed or reviewed by the AHJ — see commissioning.
5. Annual testing and maintenance for the life of the building — see annual testing requirements.

Ask each firm which of these steps they perform themselves and which they subcontract.

How to vet an ERCES or ERRCS contractor

• Credentials. The 2021 IFC Section 510.5.3 calls for an FCC General Radio Operator License (GROL) plus manufacturer or approved-school training. NICET is often accepted as a supplementary credential, but it isn't the code-mandated one. Ask who on the crew holds the GROL, and check which IFC edition your jurisdiction adopted.
• Listed equipment. Signal boosters and their enclosures should be UL 2524-listed. UL 2524 lists equipment, not people, so a contractor claiming "UL 2524 certification" for themselves is a yellow flag.
• Local AHJ track record. Ask which fire departments they've recently passed acceptance tests with. A firm that knows your fire marshal's local amendments saves real time.
• Your building type. High-rises, hospitals, parking garages, and underground structures each fail in different ways. Ask for a comparable past project.
• Pathway survivability. Ask how they'll protect cabling and equipment so the system keeps working during a fire — see pathway survivability explained.
• References. Ask for two or three building owners or GCs you can actually call.

What a complete quote should include

Quotes are hard to compare when each one leaves out something different. A complete quote should state:

• Whether the RF survey, design, permit drawings, and AHJ submittal are included
• The equipment list with model numbers, including the booster's UL 2524 listing
• How cabling and equipment will meet pathway survivability requirements
• Who handles frequency-licensee consent and FCC booster registration, if required
• The acceptance test, and what a re-test costs if the first one fails
• What's excluded — conduit, fire-rated enclosures, after-hours work, and patching are common gaps
• Annual testing and maintenance pricing, quoted separately

For budget ranges and what moves the price, see how much an ERCES system costs.

Red flags

• No references, or none from buildings like yours
• A price far below the other bids without a clear reason (often a missing survey, pathway protection, or acceptance test)
• Vague answers about which codes and editions apply in your jurisdiction
• No one on the crew holds the credential your code edition requires

Hospitals, campuses, and large mixed-use projects

On large or critical buildings, add these questions:

• How will you phase the work and testing around occupied, 24/7 areas?
• How will you reach the higher coverage bar in critical areas — the fire command center, fire pump room, and exit stairways must hit 99% coverage?
• Which agencies and frequencies (fire, police, EMS) does the system need to carry, and have you confirmed that with each licensee?
• For multiple buildings, will each have its own donor antenna and booster, and who owns annual testing across the campus?

Working against a permit or occupancy deadline

ERCES is a common reason certificates of occupancy slip. Design, AHJ review, installation, and the acceptance test all have to finish before occupancy, and the acceptance test generally needs the building close to complete. Get a contractor involved early, ask when in your schedule each step can happen, and plan backward from your target date.

Frequently asked questions

What credentials should an ERCES installer have?

The 2021 International Fire Code (Section 510.5.3) calls for an FCC General Radio Operator License (GROL) plus certification from the equipment manufacturer or an approved training program. Many AHJs also accept NICET certification as a supplementary credential. Confirm which IFC edition your jurisdiction has adopted and whether your fire marshal adds local requirements.

Is an ERCES contractor the same as an ERRCS or BDA contractor?

Usually, yes. ERCES, ERRCS (emergency responder radio coverage system), public safety DAS, and BDA system are different names the industry uses for the same kind of in-building system. When comparing firms, ask what they actually deliver — RF survey, design, installation, acceptance testing, annual testing — rather than relying on the label.

When should I bring in an ERCES contractor?

As early as you can. On new construction, the system has to be designed, submitted to the fire department, installed, and pass an acceptance test before occupancy, and the acceptance test generally needs the building close to finished. Ask your contractor when in your construction schedule each step can happen and plan backward from your certificate of occupancy date.

Can one firm handle installation and annual testing?

Many do, but not all. Some firms only perform testing and grid surveys. If you want a single point of contact for the life of the system, ask up front whether the firm offers annual testing and maintenance, and how that is priced.
