Turnkey Emergency Responder Radio Communication Systems for new construction and major renovations. NFPA 72 and IFC compliant. Nextivity-certified BDA and DAS integration with full RF surveys, AHJ coordination, and commissioning.
An Emergency Responder Radio Communication System enhances public-safety radio coverage inside buildings where signal is blocked by structure or distance from the tower.
Roof-mounted antenna captures the local public-safety frequency (700 / 800 MHz, P25 in many regions) from the nearest tower.
Amplifies the inbound signal for indoor distribution and the responder's outbound transmissions back to the tower.
A network of indoor antennas distributes the amplified signal to every floor, basement, and stairwell that fire code requires.
Building owners, GCs, and AHJs each have local concerns. These pages walk through the specific code path and JBT's installation footprint for your jurisdiction.

The standards that govern in-building public safety radio, in plain English — for architects, engineers, GCs, and code officials.
Every ERCES system needs an annual functional test and a full 5-year grid retest to stay in compliance with NFPA 1225 §14. JB Technologies runs the visit nationwide, signs the AHJ report, and offers 1 / 3 / 5-year prepay plans.
See annual test plans →State-level network rollouts (like Tennessee's TACN) change the code path for every building under their jurisdiction. These guides walk through what's required.
TACN's 700 / 800 MHz statewide rollout introduces signal-penetration challenges in modern construction. This guide covers material-by-material risk, the donor / BDA / DAS solution, and how to assess your building before AHJ inspection.
ERRCS is the work between fire alarm and electrical that nobody owns until occupancy is denied. We make sure that doesn't happen on your project.
CEL-FI Quatra 4000 and Quatra Evo design and commissioning. We carry the certification, the spares, and the carrier authorization.
Pre-construction grid testing, post-construction acceptance. We document signal levels in dBm at every test point, what AHJs want to see.
We talk to the fire marshal so you don't have to. Pre-submittal review and acceptance-test scheduling are part of the engagement, not an extra.
NFPA 72 chapter 24, IFC §510, state amendments, and AHJ-specific quirks. We know which jurisdictions require dedicated transponders, which accept Quatra, and which are still figuring it out.
Beyond ERRCS we install access control, structured cabling, fire alarm, distributed antenna systems for cellular, CCTV, and managed Wi-Fi, all from one team, in coordinated trade packages.
