• <br /> 510.8.4 The gain values of all systems used to support the signal level <br /> requirements of Section 510.4 shall be measured and the test <br /> measurement results shall be kept on file with the building owner so that <br /> the measurements can be verified each year during the annual tests. In <br /> the event that the measurement results became lost, the building owner <br /> will be required to rerun the acceptance test to re-establish that the facility <br /> provides the signal levels established in Section 510.4. <br /> 510.9 Annual equipment condition testing. <br /> 510.9.1 When an in-building radio system is required, the building owner <br /> shall test all active components of the system, including but not limited to <br /> amplifiers, power supplies, backup batteries, and related equipment, a <br /> minimum of once every 12 months. Amplifiers shall be tested to ensure <br /> that the gain is the same as it was upon initial installation and acceptance. <br /> These annual tests shall apply to both the bi-directional amplifier method <br /> of enhancing signal strength, as well as to any alternative methods that <br /> might be employed. The building owner shall notify the SERS System <br /> Manager in writing two (2) weeks in advance of when annual tests occur, <br /> and shall also notify SERS and the Fire Code Official by certified mail of <br /> the results of the test. Test records shall be retained on the inspected <br /> premises by the building owner. <br /> 510.9.2 Backup batteries and power supplies shall be tested under full <br /> load for a period of one hour to verify that, they will properly operate <br /> during an actual power outage. If within the one-hour test period, in the <br /> opinion of the testing technician, the battery exhibits symptoms of failure, <br /> the test shall be extended for additional one-hour period until the testing <br /> technician confirms the integrity of the battery. Alternative load testing <br /> which places a higher short-term demand on the battery system may be <br /> required upon verbal request by the testing technician. Batteries which fail <br /> the load test shall be replaced and retested within 10 working days. <br /> 510.9.3 All other active components shall be checked to determine that <br /> they are operating within the manufacturer's specifications for the intended <br /> purpose. <br /> 510.10 Five year signal strength testing. <br /> 510.10.1 In addition to the annual test, the building owner shall perform a <br /> radio coverage test a minimum of once every five years to ensure that the <br /> radio system continues to meet the signal strength requirements of the <br /> original acceptance test. The signal levels established in Section 510.4 <br /> and the procedures established in Section 510.8 shall apply to such tests. <br /> The results of the five-year test will be provided to SERS and the Fire <br /> 30 <br />
