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
