Implemented several years ago, the system enhances mobile and portable communications by using a sophisticated repeater system that enables radios to be heard at greater distance than the previously utilized 33 mhz conventional radios. The 2009 edition of NFPA 1 provided guidance on the design of two-way radio communication enhancement systems in Annex O. Annex O was deleted for the 2012 edition, because much of its criteria was incorporated into NFPA 72, National Fire Alarm and Signaling Code at the time. 0000063679 00000 n Similarly, the greater the distance between a radio station and a receiver, the weaker the radio signal, and the poorer the reception. For example, when a telephone call passes through a wire telephone line, some of the power in the electric current which represents the audio signal is dissipated as heat in the resistance of the copper wire.
