The Model 5900 allows condensate to collect normally in the auxiliary drain but, when confronted with the pressurized flow of water from a tripped dry valve the internal mechanism closes, shutting down any excess water from being release through the auxiliary drain. The Model 5900 does not require power, automatically resets itself after the system is repaired, and can be retrofitted onto existing auxiliary drains in dry or pre-action system (air or nitrogen). www.agfmfg.com M 82 | NFPA JOURNAL * SPRING 2022 S O C F A N N I F E O R R Ohttp://www.agfmfg.com http://www.agfmfg.com http://www.e2s.com http://www.e2s.com
