High Water Alarm KitSubmersible Liquid Level Sensor The LevelGuard High Water Alarm is a simple, effective solution to protect against bilge flooding. With a loud 100 dBA piezo horn and LED light display, this high-water alarm will alert to flooding and keep passengers, valuables and electronics safeguarded.Features:Complies with Coast Guard rule (CFR 182.530) requiring vessels 26' (7.9 meters) or more to have an audible bilge alarmNo mechanical float switches or moving parts to jam, fail, or wear outNo exposed metal probes and no electrical contacts to corrode and failNo seals to leakClean, flush-mounted alarm panel is styled to fit most decorative marine themesEasy installation1-year warrantyHow it Works:Field-Effect sensors (encased in rugged plastic) create an invisible, low-power electric field that detects fluid levels. When a conductive material, like water, enters the LevelGuard "e-field", the sensors detect its presence and trigger the alarm. Tested to millions of cycles in fluid control applications, the LevelGuard High Water Alarm performs reliably under extreme conditions of temperature, humidity, UV, vibration and salt water corrosion and is a robust solution for challenging environments. Specifications:Voltage rating: 10.5 to 14.4 VDCRequires one 1-amp fuse on positive lead to sensorDraws less than 20 microamps in standby mode, 60 milliamps in alarm mode for always-on direct wiringMultiple alarm panels (fore and aft) can be controlled by one sensorCAUTION: Do NOT connect through ignitionKit Contents:LevelGuard High Water Alarm panel (1 LED + piezo horn alarm) with 6" (152mm) wire leadsLevelGuard High Water Alarm sensor (screw-mounted) with 12" (305mm) wire leadsFuse holder
