ARC and BD System
In-Building Emergency Communication Systems
Ensure first responders have clear, reliable communication inside your building with ARCS (Auxiliary Radio Communication Systems) and BDA (Bi-Directional Amplifier) Systems.
These systems are required by NYC code in many buildings and provide:
- Always-on communication – even during power outages
- Extended radio coverage – no dead zones in stairwells, basements, or high-rise floors
- Code compliance – designed to meet FDNY and AHJ requirements

ARCS Inspection & Testing
We conduct thorough ARCS inspections and functional tests to verify performance and code compliance. Services include:
- Initial acceptance testing for new installations
- Annual and semi-annual system testing
- Signal strength verification on every floor and stairwell

Regular inspections guarantee that emergency personnel can communicate reliably when seconds matter most.
Here’s what we include when installing ARCS for your buildings
Section FC 511 of the New York City Fire Code outlines the ARCS requirements for property owners. In general, property owners must follow rules for ARCS design, installation, inspection and maintenance. ARCS requirements include (but not limited to):
New Construction:
All new construction high-rise buildings require ARCS to be installed. According to NYC rules, all buildings 75 feet or taller are considered high-rise.
Installer Qualifications:
ARCS installations must be performed by companies with the FDNY approval. COUNTY FIRE is a recognized FDNY Installer with qualified B03 technicians.
Inspection Requirements:
Newly installed ARCS must pass a Commissioning Test, as well as an FDNY acceptance test. COUNTY FIRE performs all requirements and get you the permits and approvals needed.
ARCS Maintenance:
ARCS must be in good working order; regular inspections and maintenance can ensure long-term performance. COUNTY FIRE continues to maintain and inspect your ARCS system to ensure continuous compliance.

The NYC Rules outline annual certification and five-year re-certification processes for ARCS. Annual inspections and certification are required.
