Client Case Study

JM Integrators

Dallas, TX

85% of 911 calls come from inside a building. We make sure they connect.

About JM Integrators

85% of every 911 call placed in the United States comes from inside a building, and modern construction is making it harder for those calls and the first-responder radios that respond to them to get through. JM Integrators exists to close that gap. We test, design, install, and commission the public safety DAS systems that keep first responders connected when seconds count. Founded by Jim Sowle, who spent three decades building code-compliant businesses in adjacent trades before turning his focus to in-building wireless, the company is built around two principles: do public safety work right, and be the partner other integrators trust with the RF portion of their projects.

ERRC grid testing, design, installation, and AHJ sign-off, all under one roof
Public safety focus, not a cellular shop adding ERRCS as a side service
Partner-friendly: we subcontract for fire alarm, sprinkler, and electrical integrators
Experience across new construction, renovations, and occupied buildings
Founder-led, with 30+ years of code-compliant trade experience behind every project

Which services the shop offers

Grid (ERRC/ERCES) Testing

Calibrated grid testing of your building's first-responder radio coverage, scored against the NFPA, IFC, and local AHJ thresholds that govern your jurisdiction. The starting point for every new build, remodel, or compliance project.

Public Safety / Cellular DAS / ERRCS Design & Installation

Turnkey design, donor antenna placement, BDA selection, antenna layout, and installation of the Distributed Antenna System (DAS) engineered to deliver 95%+ first-responder radio coverage throughout the building.

Renovation & Remodel Compliance

Remodels, additions, and change of occupancy often trigger new public safety radio requirements. We test, identify gaps, and bring existing buildings up to current code.

Subcontract Partnership for Integrators

Fire Alarm, Sprinkler, and Electrical integrators across the country bring us in for the Public Safety / cellular RF portion of their projects. We work behind your brand, deliver on schedule, and stay in our lane.

Commissioning & AHJ Coordination

Final acceptance testing, documentation, and direct coordination with the local Authority Having Jurisdiction (fire marshal, building official, or radio communications authority) to secure your certificate of occupancy.

Annual Testing & Maintenance

Code-required annual inspections, signal verification, and battery backup load testing to keep your DAS system continuously compliant year after year.
