Factory Installed, Calibrated and Tested

Continuous Monitoring Via BMS

Save Time

Select Ames backflow preventers now include as an option factory integrated supervisory switches on OS&Y gate valves for fire tamper detection. The TS-OSY supervisory switch is UL® Certified, Safety Signaling (Control No. 3L38). This feature eliminates manual field installations and any opportunity for error associated with installing aftermarket supervisory switches on existing backflow preventers.
