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 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
