1 SPRING LAKE PARK – BLAINE – MOUNDS VIEW FIRE DEPARTMENT FIRE REGULATIONS #-## PUBLIC SAFETY 800 MHz RADIO BUILDING AMPLIFICATION SYSTEM GOVERNING REGULATIONS IFC Section 104.1 1.0 General. Except as otherwise provided, no person shall erect, construct, change the use of or provide an addition of more than 20% to, any building or structure or any part thereof, or cause the same to be done which fails to support adequate radio coverage for the Minnesota Regional Radio Communications System, including but not limited to firefighters and police officers. This section shall not apply to: buildings of less than 8,500 square feet, or any building constructed of wood frame; provided none of the aforementioned buildings make use of any metal construction or any below-grade levels or parking areas. Any part of any R -3 occupancy building, including below-grade levels and parking areas, is exempt from the requirements of this section. For the purposes of this section, parking structures and stairwells are included in the definition of “building” and stair shafts and elevators are included in the definition of “all parts of the building.” For purposes of this section, adequate radio coverage shall be an average received field strength of no less than –93 dBm, or 1% BER, measured at 30 to 36 inches above the floor over 90% of the area of each floor and other critical areas determined by the Fire Chief or the Fire Chief's designee such as fire command centers, stairwells, elevators, high hazard areas, basements, and parking areas. Without an in-building radio system, only the received signal level standard must be achieved as the talk-out path is equivalent to the talk-in path in this regional radio system. 2.0 Amplification systems allowed. Buildings and structures which cannot support the required level of radio coverage shall be equipped with either a radiating cable system or an internal multiple antenna system with FCC type accepted bi-directional 800 MHz amplification as needed. If amplification is used in the system, all required FCC authorizations must be obtained prior to the use of the system. 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 and/or generator system for a period of at least 12 hours without external power input. The battery system shall automatically charge in the presence of an external power input.
