Dual Bilge Pump Switch w/ High Water Alarm Buzzer
Unmatched 7 Year Limited Warranty
The Dual System 257 from Water Witch, Inc. offers boat owners and manufacturers two systems in one product; primary protection, to activate a bilge pump when it senses the presence of water and a secondary system for added protection or a backup against primary system failure. The 257s monitoring system is constantly on guard and will activate the primary bilge pump when it detects water for 8 continuous seconds. The 257s secondary system will activate only when high water levels are detected for 2 continuous minutes. The monitoring and secondary systems work hand-in-hand to provide previously unavailable protection in one electronic control. The 257 can be connected to any auxiliary system such as a second bilge pump, audio alarm or visual alarm. Includes buzzer
