510.5.2 If any part of the installed system or systems contains an electrically powered component, the system shall be capable of operating on an independent battery system for a period of at least twelve (12) hours without external power input.The battery system shall automatically charge in the presence of an external AC power input. 510.5.3 A request for uplink testing to the SNO911 radio system should be made to SNO911 at least 72 hours in advance PRIOR to the BDA/DAS being turned on. 510.8 Initial Inspection and Signal Strength Acceptance Test Procedures. 510.8.1 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 510.4 and 510.5. 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 510.4.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 510.4 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 510.4. 510.8.2 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 test.After the 40 area test, if the system continues to fail,the building owner shall have the system altered to meet the coverage requirement established in Section 510.4. 510.8.3 The test shall be conducted using a SNO911 a. A spot located approximately in the center of a grid area will be selected for the test, then the radio transmitter will be activated to verify two-way communications to and from the outside of the building through the SNO911 system. Once the spot has been selected, prospecting for a better spot within the grid area will not be permitted. 510.8.4 The gain values and isolation levels of all systems used to support the signal level requirements of Section 510.4 shall be measured and the test measurement results shall be kept on file with the building owner so that the measurements can be verified each year during the annual tests. In the event that the measurement results became lost, the building owner will be required to rerun the acceptance test to re-establish that the facility provides the signal levels established in Section 510.4. 510.9 Annual equipment condition testing. 510.9.1 When an in-building radio system is required,the building owner shall test all active components of the system, including but not limited to amplifiers, power supplies, backup RE FIRE CODE ORDINANCE Page 15 of 39
