Abstract

LED light assemblies (20) are spaced over a geographical territory defined by a central dispatch of public service personnel operating in the geographical territory and are controlled by transmitting digital packets on a first radio frequency reserved for public safety personnel from a central transceiver (24) to repeaters (26) in the geographical territory and re-transmitting the digital packets on a different second frequency reserved for public safety personnel from the repeaters (26) to the light assemblies (20). In turn, the light assemblies (20) transmit digital radio signals on frequencies reserved for public safety personnel to the repeaters (26) for re-transmission to the central transceiver (24). A plurality of emergency signaling devices (36) transmit digital radio signals on the channels of frequencies reserved for public safety personnel to the light assemblies (20) to transmit a radio signal on the reserved frequencies to the central transceiver (24), a 9-1-1 alert or the like.
