Product Description

SR-500 Stingl Switch (Safety Vacuum Release System)

The Model SR-500 is a Safety Vacuum Release System (SVRS) which works by monitoring the vacuum on the suction side of the pool or spa pump. When a blockage occurs in the main drain or skimmer a sudden rise in vacuum will cause the SR-500 to shut down pump operate and activate an audible alarm. The pump will remain off with the alarm sounding until manually reset.

Features and Benefits:

• Complies with ASME/ANSI 112.19.17 as required by the International Building Codes (IBC) and the International Residential Codes (IRC)
• Meets all current codes and standards for SVRSs on new and existing pools and spas
• Can act as pool controller with programmable timer, or as stand alone SVRS working in conjunction with existing pool controller
• Newest state-of-art NEC microprocessor technology-- guaranteed reliability and performance
• Vacuum monitored 128 times per second -- rapid response and accurate readings
• Power monitored 50/60 times per second -- insures continuous power detection
• Can act as a pool and spa controller - with fully programmable 24 hour timer, or as stand alone SVRS working in conjunction with existing pool and spa controller
• Integrates with existing timer box - (for easy retrofit)
• Low vacuum sensing - (prevents cavitations or running the pump dry, eliminating costly equipment failure)
• 30 minute maintenance override - (for pool or spa service)
• Accessible extra dry contact – auxiliary equipment can be add ready added
• Power back-up – insures settings and reading will be saved (30 minute rapid recharge)
• Display error readout - (prevents guessing during troubleshooting)
• Works on all size pumps
• Easy and trouble free installation - (no pipes to cut or glue)
• Turns off pump in milliseconds upon detecting sudden vacuum change
• Multiple audible alarm capabilities – allows for quicker alert to harmful to harmful situations
• Provides a layer of protection, reducing entrapment risk
