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 operation 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 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 situations
  • Provides a layer of protection, reducing entrapment risk
