BDA placement is not guesswork. It directly impacts ERCES performance, signal strength, and long term system reliability.

The right placement helps avoid interference, coverage issues, and failed inspections before they become problems in the field.

A failed radio coverage test led Century Plastics to evaluate ERCES requirements across two manufacturing facilities in Macomb Township.

The challenge was not just meeting code. It was finding a solution that matched the actual coverage gaps without unnecessary cost or complexity.

WZC Networking reviewed the existing proposal, analyzed the site conditions, and developed a clean, practical ERCES design focused on compliance, reliability, and long term serviceability.

The result was a right sized system built to support AHJ approval and operational confidence moving forward.

Wireless Infrastructure Designed Once. Done Right.

Your donor antenna is exposed to the elements every day.
Over time, weather, connection wear, and environmental changes can impact system performance. Routine maintenance helps keep your ERCES system reliable, compliant, and ready when it matters most.

Most buildings don’t fail ERCES by choice.
They fail at the grid test.

This is what your AHJ report actually shows.
Pass. Marginal. Fail.

If you are not meeting NFPA 1225, expect delays, added costs, and rework.

Plan early. Design it right the first time.

NFPA 1225 and IFC 510 compliance is not optional.

Your ERCES system must meet coverage requirements, use UL 2524 listed equipment, include 2 hour fire rated pathways, FACP monitoring, battery backup, and annual testing for AHJ approval.

Miss one requirement and you risk failed inspections, grid test failures, and occupancy delays.

Wireless Infrastructure Designed Once. Done Right.

Donor antenna size is not a preference. It is a performance decision.

It is one of the easiest places to cut corners and one of the first places systems fail.

Dan Smith explains what actually matters when selecting the right donor antenna for your ERCES system.

This is how you stay ahead of inspections, not behind them.

Local roots. National footprint. Family at the core. ❤️

All three of these guys carry the Wierzgac name in everything they build at WZC. That is not a coincidence... that is a commitment.

We do it all in house because we treat every project like it is our own. No handoffs. No outsourcing. Just people who care about the outcome as much as you do.

When first responders are in the building, signal failure isn’t an option. ⛑️

Honored to speak at the Oakwood Group Birmingham Fire Department Training Seminar: a packed room, real conversations, and real-world applications that matter.

We’re grateful for every opportunity to educate, connect, and show up for the people who show up for all of us. More from this day coming soon.
