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 multitude of wireless transceivers, each of the transceivers having a plurality of settable operating frequencies for communicating with at least one of the first signal devices and at least one of the second signal devices; and

    a computer for configuring the multitude of wireless transceivers by determining a specified frequency for each of the wireless transceivers to associate each of the defined areas with one of the transceivers;

    wherein when one of the first signal devices associated with the one of the defined areas generates one of the primary signals to indicate one of the specified events relating to the one of the defined areas, said one of the first signal devices sends an activation signal to the one of the transceivers associated with said one of the areas, and said one of the transceivers is activated by the activation signal, and in response, the one of the transceivers activates one or more of the second signal devices associated with said one of the defined areas to generate one or more of the supplemental signals to confirm that said one 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; and

    wherein the computer communicates with a global timing system to provide an automatic alert signal based on a synchronized time.
