Abstract
A fire protection system includes a dry pipe system and a controlled discharge gas vent. The dry pipe system and controlled discharge gas vent operate using a breathing cycle to displace oxygen and/or water vapor from within the piping network of the dry pipe system. The controlled gas discharge vent allows displacement of pressurized air with nitrogen, for example, using manual or automated processes that can employ one or more sensors. Corrosion resulting from oxygen, water, and/or microbial growth is reduced or nearly eliminated.
