A pool guard alarm provides constant security at one or more entrances to a pool area. The alarm utilizes a delay timer to provide an authorized entrant the ability to enter the pool area and reset the alarm before an audible alarm is sounded. The alarm further guards against pool entrances being left inadvertently open by sounding an audible alarm if a pool access point is not closed within a specified time period after being opened.
