Stingl Switch Vacuum Safety Release System 120/240V SR500
The Stingl SR-500 Safety Vacuum Release System (SVRS) is designed to provide a critical layer of safety for your pool or spa by actively monitoring the vacuum on the suction side of your pump. When a blockage occurs-such as at the main drain or skimmer-the SR-500 detects the sudden spike in vacuum, instantly shuts down the pump, and can activate an optional audible alarm for immediate alert. The system remains off and the alarm sounds until manually reset, ensuring maximum protection against entrapment hazards.
Key Features
- Rapid Response: Monitors vacuum 128 times per second for immediate detection and action, shutting down the pump in milliseconds when a blockage is sensed.
- Programmable 24-Hour Timer: Acts as both a safety device and a fully programmable pool/spa controller, or operates as a standalone SVRS with your existing controller.
- Easy Retrofit: Integrates seamlessly with existing timer boxes-no need to cut or glue pipes for installation.
- Maintenance Mode: Includes a 30-minute override for service or vacuuming, allowing uninterrupted maintenance when needed.
- Low Vacuum Sensing: Prevents pump cavitation or dry running, helping to avoid costly equipment damage.
- User-Friendly Design: Features a display with error readouts for straightforward troubleshooting and extra dry contacts for auxiliary equipment integration.
- Power Backup: Retains settings and readings with a rapid-recharge backup, ensuring reliability even during power interruptions.
- Universal Compatibility: Works with all pool and spa pump sizes and is suitable for both new and existing installations.
- Meets Safety Codes: Fully compliant with ASME/ANSI 112.19.17 and required by International Building and Residential Codes for SVRS devices.
