An ERRCS (ERRCS) is required for multi-family residential and commercial buildings that are under construction in the U.S. – if (and this is a big if) testing shows the relevant radio signals are deficient in the building. Governed by national, state and local codes, an ERRCS ensures that First Responders can communicate using their radios with personnel in and outside
a building.

The codes are interpreted and enforced by the Authority Having Jurisdiction (AHJ), who is typically the Fire Marshall. The design and installation of an ERRCS is a specialized process that involves multiple stages of design and AHJ approval. However, the final test (when the building is 95% or so complete) ultimately determines the necessity of an ERRCS. If radio signals are good, an ERRCS will not be required. In this case, more is not better.

Depending on the jurisdiction, the AHJ may specify who is allowed to test. The requirement may simply be that the test be conducted by an FCC GROL (General Radiotelephone Operator License) licensed technician; or it may specify a select number of “authorized” companies who have the relevant test equipment.

Unfortunately, the ERRCS process is complicated and varies by locale. IBWS can help you navigate the process to 1) ensure your building has the infrastructure in place to accommodate an ERRCS if testing shows it’s required; 2) ensure that the testing is done by an authorized company; and 3) to ensure that the design and installation are handled professionally and economically.
