ERCES Blog

Installing an ERCES requires more than certifications—it demands the right tools. From site survey scanners to spectrum analyzers and cable prep gear, here’s what you need for a successful setup.

ERCES code requirements vary widely by jurisdiction, causing confusion for integrators. Differences in code adoption, survivability standards, approved components, and system classifications can impact cost and deployment. Coordinating directly with the local AHJ is essential, and NFPA 1225 provides the most current national guidelines.

Building occupancy requires adequate radio signal for first responders. Coordination between the AHJ (indoor signal) and FCC Licensee (external network) is key. Improper ERCES can harm the wider network. Find the Licensee via NFPA 1225, call sign/FCC database, or municipal sites. Licensee coordination is vital for ERCES commissioning and requires a Retransmission Agreement to prevent network interference, ensuring reliable first responder communication.

Mechanical, Electrical, Plumbing, Fire Alarm and Fire Suppression are all at the top of most General Contractors' lists.  Most are not aware that while they are using materials that are cost effective or energy efficient, they are also actively creating resistance to radio signals for first responders.  So, what do they do when the building is complete, and the Building Inspector or Fire Marshal cannot connect their radios to the radio tower outside?

Reliable radio coverage is critical for First Responders, but building materials can block signals. Learn how Fire Alarm contractors can identify the need for an ERCES through site surveys, testing tools, and signal analysis—turning code compliance into a smart revenue opportunity.
