ABSTRACT:
A locator-paging system including a master kit and a plurality of sub kits, in which the master kit can be actuated to transmit a searching signal to each sub kit, causing every sub kit to transmit an answering signal. The master kit generates a warning signal when at least one sub kit does not transmit an answer back. The master kit can also be actuated to transmit paging signals to the sub kits. As a result, the sub kits are actuated to generate a sound and light alarm when a paging signal from the master kit is recognized. Furthermore, the sub kits can be actuated to transmit a paging signal to the master kit which causes the master kit to generate a sound and light alarm, indicating which sub kit is calling.
