Method and apparatus for pool alarm system

Abstract

a pool alarm system in combination with a swimming pool comprising: a detection mechanism for detecting intrusion into the pool and generating a detection output signal; a first alarm receiving the detection output signal and sounding the first alarm; a timer circuit triggered by the first alarm and generating a timer exceeded output signal after a predetermined time has lapsed; a second alarm receiving the timer exceeded output signal and sounding the second alarm; and a stop mechanism to shut off the first alarm and the second alarm; wherein the first alarm is a local alarm to be heard by people inside or around the pool and the second alarm is a general alarm to be heard by surrounding neighbors. Also described is a method for detecting intrusion in a swimming pool comprising: activating a first low-level intensity alarm to alert a person in the pool without disrupting a surrounding area; providing a stop mechanism manually accessible near an edge of the swimming pool for deactivating the first alarm; activating a second higher-level intensity alarm to alert the surrounding area if the first alarm has not been deactivated within a predetermined time following its activation.
