What is DAS?
Understanding the in-building radio infrastructure that Florida law requires — and what it means for your project.
Distributed Antenna System (DAS)
A Distributed Antenna System — commonly called DAS — is a network of small antennas installed throughout a building to extend and strengthen radio signal coverage. In the context of public-safety compliance, DAS refers specifically to the infrastructure that allows first responders (police, fire, EMS) to communicate reliably on their radio systems inside your building.
Without adequate in-building coverage, a firefighter on the third floor may not be able to reach dispatch, or an officer in a parking garage may lose contact with their unit. Florida law requires building owners to address this before a Certificate of Occupancy is issued.
How it works
A DAS for public safety typically consists of a signal source (a donor antenna or connection to the public-safety radio network), a bi-directional amplifier (BDA) to boost the signal, and a distribution network of cables and antennas placed throughout the building. The system is engineered, installed, tested, and approved by the local Authority Having Jurisdiction (AHJ) — usually the fire marshal.
Not the same as commercial cellular DAS
Public-safety DAS is separate from the cellular DAS systems used to improve phone signal in large venues. Public-safety systems operate on dedicated first-responder radio frequencies and must meet specific performance standards set by Florida Statute 633.202 and local fire codes. A commercial cellular booster does not satisfy the public-safety requirement.
Why Florida requires it.
Florida Statute 633.202 (18)(a) mandates in-building public-safety radio coverage for most new commercial construction and significant renovations. The requirement took effect January 1, 2025.
Life safety mandate
The requirement exists because first responders must be able to communicate inside buildings during emergencies. Signal dead zones cost lives.
Effective January 1, 2025
Buildings permitted on or after January 1, 2025 must demonstrate compliance before a Certificate of Occupancy is issued.
Jurisdiction variation
While the state statute sets the baseline, individual AHJs — county and city fire marshals — may apply stricter standards. What satisfies one jurisdiction may not satisfy another.
Who designs, installs, and approves it.
A licensed Florida engineer (typically electrical or fire protection) must design the system. A licensed contractor installs it. The local AHJ — usually the fire marshal — conducts the final inspection and issues approval.
Beacon Safety Partners does not design or install DAS systems. We are independent consultants who identify the requirement early, help you assemble the right team of licensed professionals, and coordinate the process from assessment through AHJ approval — so nothing falls through the cracks.
Where Beacon fits in.
01
Identify the requirement
We review your project scope and jurisdiction to confirm whether the requirement applies and what standard your AHJ enforces.
02
Assemble the right team
We connect you with qualified engineers and licensed contractors who have experience with public-safety DAS in your jurisdiction.
03
Coordinate the process
We manage timelines, documentation, and communication between your project team, the DAS contractor, and the AHJ.
04
Support through approval
We stay with you through final inspection and AHJ sign-off — so your CO is not delayed by a compliance gap discovered at the last minute.
