Stingl Switch SR-500 Safety Vacuum Release System (SVRS) - 120V/240V
Protect swimmers from suction entrapment with the Stingl Switch SR-500, a high-speed Safety Vacuum Release System that monitors suction-side vacuum and shuts down the pump in milliseconds when an obstruction is detected. Engineered for residential and commercial pools and spas, the SR-500 meets the ASME/ANSI A112.19.17 safety standard referenced by the International Building and Residential Codes.
Key Features:
- Rapid Vacuum Monitoring: Samples suction-side vacuum 128 times per second for exceptionally fast, accurate response to sudden changes.
- Millisecond Pump Shutoff: Cuts power to the pump within milliseconds of detecting a blockage, reducing the risk of entrapment injury.
- Dual-Voltage Compatibility: Works on both 120V and 240V single-phase pump circuits for flexible installation.
- Programmable 24-Hour Timer: Built-in timer lets you schedule daily pump run cycles without adding a separate controller.
- Dry-Run Protection: Low-vacuum sensing prevents cavitation and dry running to help avoid costly pump damage.
- Service Override: 30-minute maintenance override simplifies routine pool and spa service calls.
- Audible Alarms: Multiple alarm tones provide clear alerts to unsafe conditions.
