FIRE CODE ORDINANCE Page 16 of 38 <br /> <br />3. The frequency ranges which must be supported shall be 746—824 MHz and 851—869 MHz; and <br />4. The signal strengths shall be present at a 100% reliability factor at the -95 dBm level. <br /> <br />510.5. Amplification Systems <br /> <br />510.5.1 Buildings and structures that cannot support adequate radio coverage, as identified, <br />shall be equipped with either a radiating cable system or an internal multiple antenna system <br />with FCC type accepted bidirectional amplifiers as needed. <br /> <br />510.5.2 If any part of the installed system or systems contains an electrically powered <br />component, the system shall be capable of operating on an independent battery system for a <br />period of at least twelve (12) hours without external power input. The battery system shall <br />automatically charge in the presence of an external AC power input. <br /> <br />510.5.3 A request for uplink testing to the SNO911 radio system should be made to SNO911 at <br />least 72 hours in advance PRIOR to the BDA/DAS being turned on. <br /> <br />510.8 Initial Inspection and Signal Strength Acceptance Test Procedures. <br /> <br />510.8.1 When an engineering study performed for the building contractor or owner has <br />determined that an in-building radio system is required, and upon completion of installation, it <br />will be the building owner’s responsibility to have the radio system tested to ensure that two- <br />way communications 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 into a grid of <br />approximately 20 equal areas. A maximum of two nonadjacent areas will be allowed to fail the <br />test by not meeting the minimum signal levels established in Section 510.4. Testing of parking <br />garages, stairwells, and non-enclosed areas will be performed as separate tests with statistics <br />gathered separately for signal levels in the primary structure and parking areas. Signal levels <br />shall meet the requirements of Section 510.4 for all areas enclosed by the structure and <br />statistical methods shall not be used to dilute the intent of the coverage requirements <br />established in Section 510.4. <br /> <br />510.8.2 In the event that three of the areas fail the test, in order to be more statistically <br />accurate, the floor may be divided into 40 equal areas. In such an event, a maximum of four <br />nonadjacent areas will be allowed to fail the test. After the 40 area test, if the system continues <br />to fail, the building owner shall have the system altered to meet the coverage requirement <br />established in Section 510.4. <br /> <br />510.8.3 The test shall be conducted using a SNO911 a. A spot located approximately in the <br />center of a grid area will be selected for the test, then the radio transmitter will be activated to <br />verify two-way communications to and from the outside of the building through the SNO911 <br />system. Once the spot has been selected, prospecting for a better spot within the grid area will <br />not be permitted. <br /> <br />510.8.4 The gain values and isolation levels of all systems used to support the signal level <br />requirements of Section 510.4 shall be measured and the test measurement results shall be
