channels placed in operation by SERS. Consultation with the SERS System Manager shall be required to determine if the specific installation requires this additional filtering. 511.5.4 The SERS System Manager shall be notified two weeks in advance of when an amplification system is installed and operational. 511.6 Alternative methods. Other acceptable methods of providing in-building coverage may also include construction of low-power `filler' trunked radio sites that are integrated into the SERS. These alternative approaches may be considered where the use of bi-directional amplifiers proves impractical. Such alternative methods will require the involvement of SERS representatives in the design process. The requirements established by Sections 511.4, 511.5.2, 511.5.3, and 511.5.4 apply to any such alternate methods. 511.7 Additional requirements for new construction or substantial revisions to structures. Any person who constructs or develops a commercial or industrial building or structure of any size and type of construction that is likely to attenuate radio frequency signals shall provide two-inch non-conductive raceways in the walls into which radiating or coaxial cable may be laid. Such raceways shall include an easily accessible opening to the roof surface that allows for placement of an exterior antenna and riser access within the building core to each floor within the structure. 511.8 Initial Inspection and Signal Strength Acceptance Test Procedures. 511.8.1 When an engineering study performed for the building contractor or owner has determined that an in-building radio system is required, and upon completion of installation, it will be the building owner's responsibility to have the radio system tested to ensure that two-way communications coverage on each floor of the building meets the requirements established in Sections 511.4 and 511.5. Each floor of the building shall be divided into a grid of approximately 20 equal areas. A maximum of two nonadjacent areas will be allowed to fail the test by not meeting the minimum signal levels established in Section 511.4. Testing of parking garages, stairwells, and non-enclosed areas will be performed as separate tests with statistics gathered separately for signal levels in the primary structure and parking areas. Signal levels shall meet the requirements of Section 511.4 for all areas enclosed by the structure and statistical methods shall not be used to dilute the intent of the coverage requirements established in Section 511.4. 511.8.2 In the event that three of the areas fail the test, in order to be more statistically accurate, the floor may be divided into 40 equal areas. In such an event, a maximum of four nonadjacent areas will be allowed to fail the 20
