Pool alarm system including motion detectors and a drain blockage sensor |
摘要 |
A pool alarm system including a programmable control circuit, a control keypad, a number of planar focused infrared motion detectors, a key alarm system activation switch, an audible alarm output system, a drain blockage sensor, and a pool pump motor control relay. The drain blockage sensor is installed in place of the existing drain cover and includes a perforated dome shaped cover member slidably mounted to a compression detector including a spring biased plunger slidably mounted within a plunger cylinder. The spring biased plunger has a permanent magnet secured to a plunger bottom surface thereof. The plunger cylinder has a magnetically actuated reed switch in electrical connection with a drain stoppage input of the programmable control circuit and positioned on a bottom cylinder surface thereof. Each of the number of planar focused infrared motion detectors has an infrared sensing area having a planar bottom to allow for sensing motion at or a near a pool water surface.
