Abstract
A protective alarm system for encompassing an area to be protected, such as a swimming pool, includes an enclosure arrangement having at least one and preferably a plurality of flexible hoses that are filled with fluid and substantially enclose or surround the perimeter of the area to be protected. The protective alarm system also includes a detector mechanism connected to the enclosure arrangement and capable of detecting change in the fluid pressure caused by transfer of the weight of a person to compress the hose by stepping thereon. The protective alarm system further includes an alarm device connected to the detector mechanism and operable to generate an alarm signal in response to detection by the detector mechanism of a change in the fluid pressure in the hoses.
