established by Sections 510.4, 510.5.2, 510.5.3, and 510.5.4 apply to any <br /> such alternate methods. <br /> 510.7 Additional requirements for new construction or substantial revisions <br /> to structures. Any person who constructs or develops a commercial or <br /> industrial building or structure of any size and type of construction that is <br /> likely to attenuate radio frequency signals shall provide two-inch non- <br /> conductive raceways in the walls into which radiating or coaxial cable may <br /> be laid. Such raceways shall include an easily accessible opening to the <br /> roof surface that allows for placement of an exterior antenna and riser <br /> access within the building core to each floor within the structure. <br /> 510.8 Initial Inspection and Signal Strength Acceptance Test Procedures. <br /> 510.8.1 When an engineering study performed for the building contractor <br /> or owner has determined that an in-building radio system is required, and <br /> upon completion of installation, it will be the building owner's responsibility <br /> to have the radio system tested to ensure that two-way communications <br /> coverage on each floor of the building meets the requirements established <br /> in Sections 510.4 and 510.5. Each floor of the building shall be divided <br /> into a grid of approximately 20 equal areas. A maximum of two <br /> nonadjacent areas will be allowed to fail the test by not meeting the <br /> minimum signal levels established in Section 510.4. Testing of parking <br /> garages, stairwells, and non-enclosed areas will be performed as separate <br /> tests with statistics gathered separately for signal levels in the primary <br /> structure and parking areas. Signal levels shall meet the requirements of <br /> Section 510.4 for all areas enclosed by the structure and statistical <br /> methods shall not be used to dilute the intent of the coverage <br /> requirements established in Section 510.4. <br /> 510.8.2 In the event that three of the areas fail the test, in order to be <br /> more statistically accurate, the floor may be divided into 40 equal areas. In <br /> such an event, a maximum of four nonadjacent areas will be allowed to fail <br /> the test. After the 40 area test, if the system continues to fail, the building <br /> owner shall have the system altered to meet the coverage requirement <br /> established in Section 510.4. <br /> 510.8.3 The test shall be conducted using a SERS approved portable <br /> radio, communicating through the SERS as specified by the authority <br /> having jurisdiction. A spot located approximately in the center of a grid <br /> area will be selected for the test, then the radio transmitter will be <br /> activated to verify two-way communications to and from the outside of the <br /> building through the SERS system. Once the spot has been selected, <br /> prospecting for a better spot within the grid area will not be permitted. <br /> 29 <br />
