Why it matters
Why buildings need ERCES
- Modern construction kills up to 80% of public-safety radio signal — first responders can lose contact inside your building.
- ERCES is code-mandated under IFC 510 and NFPA 1225 — AHJs increasingly require proof of coverage before sign-off.
- A failed benchmark test can hold up your certificate of occupancy or trigger a citation.
- WZC designs, installs, and certifies on the COMBA CriticalPoint platform — and owns the AHJ relationship so you pass the first time.
The free assessment tells you where your building stands before any of that becomes a problem.
