APPENDIX L <br />506 2015 MINNESOTA STATE FIRE CODE <br />supervisory service, or when approved by the fire <br />code official, shall sound an audible signal at a con- <br />stantly attended location. <br />4. Equipment shall have FCC certification prior to <br />installation. <br />L104.2.5 Additional frequencies and change of fre- <br />quencies. The emergency responder radio coverage sys- <br />tem shall be capable of modification or expansion in the <br />event frequency changes are required by the FCC or addi- <br />tional frequencies are made available by the FCC, or pub- <br />lic safety entities operating in a given jurisdiction make <br />modifications, changes, or upgrades to their communica- <br />tion system(s) that change the frequencies such systems <br />utilize. <br />L104.2.6 Availability. The in-building coverage system, <br />in general, shall operate according to its intended specifi- <br />cation with “5-9s” availability of 99.999 percent of each <br />year; i.e., no critical component of the system shall be out <br />of normal operation for more than 5.26 minutes of each <br />year. <br />L105 Installation requirements. The installation of the pub- <br />lic safety radio coverage system shall be in accordance with <br />Sections L105.1 through L105.4. <br />L105.1 Approval prior to installation. Amplification sys- <br />tems capable of operating on frequencies licensed to any pub- <br />lic safety agency by the FCC shall not be installed without <br />prior coordination and approval of the fire code official. <br />L105.2 Minimum qualifications of personnel. The mini- <br />mum qualifications of the system designer and lead installa- <br />tion personnel shall include at least one of the following: <br />1. Certification of in-building system training issued by a <br />nationally recognized organization or school. <br />2. A certificate issued by the manufacturer of the equip- <br />ment being installed. <br />These qualifications shall not be required where demon- <br />stration of adequate skills and experience satisfactory to the <br />fire code official is provided. <br />L105.3 Acceptance test procedure. When an emergency <br />responder radio coverage system is required, and upon com- <br />pletion of installation, the building owner shall have the radio <br />system tested to ensure that two-way coverage on each floor <br />of the building is a minimum of 95 percent. The test proce- <br />dure shall be conducted as follows: <br />1. Each floor of the building shall be divided into a grid of <br />20 approximately equal test areas. <br />2. The test shall be conducted using a calibrated handheld <br />or hip-worn device of the latest brand and model used <br />by the agency talking through the agency’s radio com- <br />munications system. <br />3. Failure of a maximum of two nonadjacent test areas <br />shall not result in failure of the test. <br />4. In the event that three of the test areas fail the test, in <br />order to be more statistically accurate, the floor shall be <br />permitted to be divided into 40 equal test areas. Failure <br />of a maximum of four nonadjacent test areas shall not <br />result in failure of the test. If the system fails the 40- <br />area test, the system shall be altered to meet the 95 per- <br />cent coverage requirement. <br />5. A test location approximately in the center of each test <br />area shall be selected for the test, with the radio enabled <br />to verify two-way communications to and from the out- <br />side of the building through the public agency’s radio <br />communications system. Once the test location has <br />been selected, that location shall represent the entire <br />test area. Failure in the selected test location shall be <br />considered failure of that test area. Additional test loca- <br />tions shall not be permitted. <br />6. The gain values of all amplifiers, if applicable, shall be <br />measured and the test measurement results shall be kept <br />on file with the building owner so that the measure- <br />ments can be verified during annual tests. In the event <br />that the measurement results become lost, the building <br />owner shall be required to rerun the acceptance test to <br />reestablish the gain values. <br />7. As part of the installation, a spectrum analyzer or other <br />suitable test equipment shall be utilized to ensure spuri- <br />ous oscillations are not being generated by the subject <br />in-building coverage system. This test shall be con- <br />ducted at time of installation and subsequent annual <br />inspections. <br />8. A test shall be considered a “failure” when a transmis- <br />sion from the test device within the building fails to <br />deliver intelligible audio or data to the appropriate pub- <br />lic safety dispatch center or equivalent as would be <br />expected during normal operation; and/or when a trans- <br />mission from a public safety dispatch center or equiva- <br />lent fails to deliver intelligible audio or data to the test <br />device within the building as would be expected during <br />normal operation. <br />L105.4 FCC compliance. The emergency responder radio <br />coverage system installation and components shall also com- <br />ply with all applicable federal regulations including FCC 47 <br />CFR Part 90.219. <br />L106 Maintenance. The emergency responder radio cover- <br />age system shall be maintained operational at all times in <br />accordance with Sections L106.1 through L106.4. <br />L106.1 Testing and proof of compliance. The emergency <br />responder radio coverage system shall be inspected and tested <br />annually or whenever structural changes occur including <br />additions or remodels that could materially change the origi- <br />nal field performance tests. Testing shall consist of the fol- <br />lowing: <br />1. In-building coverage test as described in Section <br />L105.3. <br />2. Signal boosters in-building coverage systems shall be <br />tested to ensure that the gain is the same as it was upon <br />initial installation and acceptance. <br />3. Backup batteries and power supplies shall be tested <br />under load of a period of one hour to verify that they <br />will properly operate during an actual power outage. If, <br />within the one-hour test period, the battery exhibits <br />symptoms of failure, the test shall be extended for addi- <br />M <br />N <br />M <br />N <br />M <br />N <br />MN <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />MN <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />MN <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />NM <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />NM <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />M <br />N <br />M <br />N <br />M <br />NM <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />MN <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />MN <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />MN <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />MN <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />N <br />M <br />Copyright © 2016 ICC.
