glazing and window frames, or any below-grade storage or parking areas. 510.3.2 Any person required to maintain adequate radio coverage as specified in Section 510.3.1 above shall obtain a "Letter of Provisional Authorization" from SNO911 at the time a building permit application is submitted to the city of Everett. Written evidence of such prior written notification shall be given to the city of Everett Building Official before a building permit application will be accepted. 510.3.3 Persons constructing new or remodeled facilities which include systems intended for providing in-building service for other wireless services shall make provisions for including public safety radio signals into such system.This capability shall at a minimum include provision of bidirectional amplification as required. This requirement shall apply to structures of all sizes whenever such in-building wiring or services are to be provided. 510.3.4 No person shall install devices specifically intended to prevent the reception of signals intended for cellular telephones, pagers, wireless communications devices, or public safety radios in buildings of any type or size. 510.3.5 No person shall install or use building materials specifically marketed or engineered to prevent the ingress of radio signals, except where such materials may be required to shield laboratory or research facilities. Use of any such materials in laboratory or research facilities shall be clearly noted in any construction permit application documents and written notification of the use of any such materials shall be provided to SNO911 at the time of permit application submittal. Signs notifying occupants, emergency services and law enforcement personnel of such shielding conditions shall be conspicuously posted both at the entrance and on the interior of such areas. 510.4. Performance. A study shall be prepared and reviewed prior to plan approval that demonstrates that the signal levels within the proposed structure meet or exceed the criteria established below. Multiple carrier environments shall take into account the presence of non-SNO911 signals in the design of the amplifier system. Adequate Radio Coverage shall include all of the following measurement requirements: 1. A minimum signal strength of-95 dBm available in 90%of the area of each floor of the building when transmitted to a belt-worn portable radio equipped with a speaker microphone; 2. A minimum signal strength of-95 dBm received at the SNO911 site when transmitted from a belt-worn portable radio equipped with a speaker microphone from 90%of the area of each floor of the building; 3. The frequency ranges which must be supported shall be 746-824 MHz and 851-869 MHz; and 4. The signal strengths shall be present at a 100% reliability factor at the -95 dBm level. 510.5. Amplification Systems 510.5.1 Buildings and structures that cannot support adequate radio coverage, as identified, shall be equipped with either a radiating cable system or an internal multiple antenna system with FCC type accepted bidirectional amplifiers as needed. in FIRE CODE ORDINANCE Page 14 of 39
