Claim:
1. A system to activate supplemental signals in response to primary signals, the system comprising: a plurality of first signal devices for generating the primary signals, each of the first signal devices being associated with one of a plurality of defined areas to generate one of the primary signals to indicate specified events associated with said one of the plurality of defined areas; a plurality of second signal devices for generating the supplemental signals, each of the second signal devices being associated with one of the defined areas; a plurality of transceivers for selectively activating the second signal devices in response to the primary signals generated by the first signal devices, each of the plurality of transceivers having a settable operating frequency for associating said each transceiver with a respective one of the defined areas, and each of the first signal devices being associated with one of the plurality of transceivers; and a control to set the operating frequencies of the plurality of transceivers to associate each of the transceivers with a respective one of the defined areas; wherein when each of the first signal devices generates one of the primary signals to indicate one of the specified events relating to the one of the defined areas associated with said each first signal device, said each first signal device sends an event signal to the one of the transceivers associated with said one of the defined areas, and in response, the one of the transceivers sends an activation signal to the one or more of the second signal devices associated with said one of the defined areas, and each of the one or more of the second signal devices generates one of the supplemental signals to confirm that said each of the first signal devices has generated one of the primary signals to indicate the one of the specified events related to said one of the defined areas.
