From a single grid test to a full design-build, Zion runs every part of the ERCES lifecycle in-house — under one Texas license, one design platform, one accountable team.
We track IFC adoption and amendments across 91 Texas jurisdictions, from Dallas to Houston to El Paso. The same database powers our internal estimates and the public-facing Building Signal Check tool.
Predictable, scheduled, AHJ-ready annual signal-survey testing. PCTEL-instrumented grid testing, deficiency reports, and Fire Marshal submittals — turnkey.
iBwave-certified design, UL 2524 BDA installation, and AHJ acceptance — sequenced so your CO doesn't slip. We close ERCES permits fast.
Fire alarm, sprinkler, special hazards, and BDA from one Texas-licensed contractor. One submittal, one inspection coordination, one accountable partner.
PCTEL-instrumented signal surveys per IFC §510.5.3. Pre-installation baseline or annual recertification.
iBwave-certified DAS layouts, antenna/cable schedules, AHJ frequency authorization, plan submittal.
UL 2524 listed BDAs (RSI / Honeywell / Fiplex), distributed antennas, fire-rated pathway, NEMA enclosures, full grounding.
Acceptance testing, AHJ submittal, monitoring integration, and annual recertification on a recurring schedule.
Joel Sadowsky founded Zion to solve a specific problem: building owners deserve a single Texas-licensed contractor who can run fire alarm, sprinkler, special hazards, and ERCES from one shop — without bouncing between subs and AHJs. The BDA / ERCES division is the newest pillar of that promise.
