Complies with ASME/ANSI 112.19.17. Works on all size pumps. easy to install. No pipes to cut or glue.

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 - ensures 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 – ensures 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
