A “Benchmark Test,” “Grid Test,” or “RF Survey” refers to a test of your building’s public safety network coverage and performance, as mandated by the International Fire Code (IFC) Section 510 and NFPA 1225 §5.1.
This assessment is a crucial step in the ERCES installation process, as it allows technicians to fully evaluate the specific needs and challenges of the building in terms of providing reliable two-way radio communication for emergency responders.
The Benchmark Test or Grid Test involves taking detailed measurements and signal strength readings throughout your property to map out existing public safety radio coverage. NFPA 1225 §5.1 requires this survey to be completed before system design begins, establishing the baseline that the Authority Having Jurisdiction (AHJ) uses to determine whether an ERCES is required and what coverage areas must be addressed.
This data is also used to design a customized ERCES solution that ensures your building meets all regulatory requirements and provides the necessary communication capabilities. Conducting this thorough assessment upfront is essential for ensuring the final ERCES installation is properly tailored to the unique characteristics of your building and will function reliably when needed during an emergency. That’s why it’s a key part of the comprehensive ERCES installation services we provide.
