Protect Lives & Property through Reliable Emergency Communications
Maximum Compliance. Minimum Cost.
Independent Emergency Responder Communication Enhancement Systems (ERCES) testing for construction, final acceptance, and annual compliance — helping contractors, integrators, and building owners across California reduce rework, pass inspection faster, and protect long-term system performance.
Independent Testing
HetNet doesn't manufacture or install ERCES equipment. We have no bias relationships and nothing to protect except the accuracy of our results. That independence is what makes our reporting defensible — for contractors, integrators, and building owners alike.
Annual Compliance
Annual ERCES testing is required by California Fire Code — and your documentation needs to be current when the AHJ asks for it. HetNet's service agreements provide scheduled testing, updated compliance reports, and ongoing support so you're never caught unprepared.
Testing Services
-
Maintain annual compliance and long-term system readiness through scheduled testing, service agreements, and post-construction support.
-
Validate performance with an independent third party before the inspection becomes a problem. HetNet helps teams document results, reduce surprises, and move toward approval with more confidence.
-
Reduce construction cost by finding issues earlier, avoiding late-stage corrections, and protecting schedule and occupancy timelines.
-
Keep buildings compliant after turnover. HetNet supports annual testing, recurring reporting, and ongoing service agreements so owners can stay ahead of issues instead of reacting to them.
-
Catch issues early, while fixes are still manageable. HetNet helps project teams identify coverage and compliance problems before they turn into change orders, delays, and expensive rework.
-
Add ERRCS scope with confidence through an independent testing partner that validates performance, supports acceptance, and helps protect your install.
