We design, install, and support the full spectrum of low-voltage and building technology systems. Serving commercial, industrial, education, healthcare, senior living, and enterprise facilities nationwide.
Emergency Responder Communication Enhancement Systems designed for IFC and NFPA 1225 compliance — engineered, installed, and AHJ-accepted for commercial and multifamily buildings across the Southeast.
The International Fire Code requires that new and existing buildings provide adequate in-building radio coverage for emergency responders. Buildings that fail the coverage test cannot receive a Certificate of Occupancy — and owners of existing buildings that fail annual testing face enforcement action. An ERCES system that is designed without a pre-installation RF survey, or installed without proper donor antenna placement and cable loss calculations, will not pass AHJ acceptance testing.
JB Technologies designs and installs complete ERCES/BDA systems for commercial buildings, multifamily properties, parking structures, and tunnels throughout Georgia, Tennessee, Alabama, Florida, and the Carolinas. We work directly with the local AHJ and fire marshal to meet jurisdiction-specific requirements and deliver systems that pass acceptance testing the first time.
Every ERCES design begins with a pre-installation RF signal survey to identify donor signal strength, coverage gaps, and the amplification required. We calculate cable loss, antenna placement, power splitting, and BDA output levels to deliver code-compliant coverage throughout the building.
We install, program, and commission bi-directional amplifiers in equipment rooms with proper power, grounding, and monitoring connections. BDA equipment is selected to match the frequency bands required by the local AHJ — which varies by jurisdiction and public safety radio system.
Indoor antenna systems are designed to provide uniform signal coverage throughout the building. We install omni and directional antennas in stairwells, corridors, parking levels, and below-grade spaces where signal penetration is insufficient.
We perform all required system testing per NFPA 1225 and IFC requirements, and coordinate directly with the local fire marshal for acceptance. We prepare and submit all required documentation, and attend the acceptance test to ensure the system is approved and the CO is not delayed.
IFC and local fire codes require ERCES in a wide range of building types. The specific threshold varies by jurisdiction — JB Technologies stays current with code adoption across all Southeast markets.
High-rise buildings where upper floors and below-grade levels are outside the range of outdoor radio signals require amplified in-building coverage.
Large apartment complexes, student housing, and mixed-use developments where building construction materials attenuate public safety radio signals below code requirements.
Below-grade and above-grade parking garages where concrete construction creates consistent coverage failures that require a dedicated antenna system.
Hospitals and medical campuses where first responder radio coverage is critical and building construction — including lead-lined walls and mechanical equipment — creates significant RF attenuation.
Large-footprint warehouse and distribution buildings where the building size prevents adequate radio coverage from perimeter base stations.
University and K-12 buildings — particularly those with thick masonry or concrete construction — where ERCES is required by local fire code or campus security policy.
BDA systems configured to amplify all public safety frequency bands used by the local jurisdiction — including VHF, UHF, 700 MHz, and 800 MHz depending on local system requirements.
Modern digital public safety radio system support for P25 Phase I and Phase II waveforms used by most major metro and county public safety agencies in the Southeast.
Complete system design and installation per NFPA 1225 Standard for the Installation of Emergency Services Communications Systems — the primary standard for ERCES design.
IFC requires annual ERCES inspection. We offer annual testing and inspection services to keep your system in compliance and maintain your CO status.
BDA equipment is FCC Part 90 Type Accepted for public safety frequencies. All equipment documentation is provided for AHJ review and building permit records.
ERCES systems with monitoring capability notify building management when BDA equipment fails — ensuring the system is operational when first responders need it.
ERCES systems must meet a combination of federal, state, and local requirements. JB Technologies stays current with code adoption across all Southeast jurisdictions.
International Fire Code Section 510 — Emergency Responder Radio Coverage — is the primary code requirement driving ERCES installation in new and existing buildings.
Standard for the Installation of Emergency Services Communications Systems — governs system design, installation methods, testing requirements, and documentation.
Federal Communications Commission rules governing signal boosters on public safety frequencies — requiring Type Acceptance of BDA equipment and coordination with the local public safety licensee.
New construction requiring CO, existing building failing coverage tests, or annual inspection service — we can help.
