Each Public Safety Communication System has to meet a minimum set of requirements. Exact requirements vary based on local jurisdiction. Check your local building and fire codes for your specific requirements. Below are some general requirements commonly adopted across the U.S.
Minimum Signal Strength: According to the NFPA and IFC, minimum signal strength of -95 dBm is required to satisfy coverage.
Equipment Enclosures: The NFPA and IFC specify that all equipment supporting the public safety network must be housed in NEMA-4 compliant enclosures.
Backup Power Solution: Equipment that supports the public safety network must be able to function for 24 hours without the primary commercial power source.
Antenna isolation: The NFPA dictates that antenna isolation must be 15 dB higher or between donor and coverage antennas.
Fire Ratings: Cables connecting public safety network equipment must meet a two-hour fire rating. This also applies to the room that the equipment is housed in.
System Frequencies: The NFPA requires that if a radio enhancement system is necessary the system must be capable of supporting all relevant frequencies as provided by the local authority having jurisdiction.
System Components: Signal boosters including BDAs, shall have FCC type acceptance and must be operated in accordance with commission rules.
System Monitoring: An automatic-monitoring system is required to report antenna malfunctions, public safety network equipment failure, power loss and battery failure or low charge..
