Guides
Plain-English guides to firefighter radio coverage
Start with the question you have. Each guide answers one thing owners, boards and managers actually ask, and cites the code, statute or fire department document behind every rule.

Start here
New to the topic? Read What is ERRCS?, then Does my building need ERRCS?. If you already have a fire marshal notice, go straight to what to do after a citation.
- Condo owner or board member? ERRCS for condo owners and boards explains it in plain words.
- Property or association manager? Your first week after a notice.
- Need one page for the next meeting? Make a Board Brief.

About the equipment
The BDA system pages cover the hardware: what it costs and how it is tested. If your paperwork uses a different name, see ERCES, ERRCS and other names.
Every guide is guidance, not engineering or legal advice. Confirm with your fire marshal (AHJ).
Who sets the rule
Four layers decide what your building owes
- Layer 1The model codeIFC Section 510, and the NFPA standard it points to (NFPA 1221, now NFPA 1225). Sets the baseline: coverage, equipment, testing.IFC 2021 510; NFPA 1225 (2022)
- Layer 2Your stateStates adopt the code and some write their own law. Florida's statute says who must comply, lists exemptions and set the high-rise dates.F.S. 633.202(18)
- Layer 3Your fire marshal (AHJ)Sets the signal level, the radio bands and the permit steps, and keeps a technical criteria document.F.S. 633.202(18)(a); IFC 2021 510.4.2.2
- Layer 4Your buildingA signal test shows whether the inside meets that level. A system is needed only where it falls short.IFC 2021 510.4.2.1; F.S. 633.202(18)(c)1
Next step
Take the board a plan, not just a problem
Ask for up to 3 quotes from vetted installers who serve your area, or start with a one-page brief the board can read before the next meeting. Free for owners, boards and managers. No texts, no cold calls.
