This will include the physical address, emergency contact information, building name, location within the building, manufacturer and model number. The Lead Agency must review and approve operation of the installed in -building coverage system to ensure proper installation and operation and to mitigate any adverse effect on the System. It is the responsibility of the equipment/facility owner to comply with all requirements of the National Fire Protection Association (NFPA), California Fire Code (CFC) and Federal Communications Commission (FCC) including licensing, location reporting, and interference mitigation.
