Jim- Thanks for the input, does make sense. Have you ever ran across that situation where the line running into the room needs to be dry?

Since that time it has saved a lot of trouble.

Reading through NFPA-72 seems like the preferred method is a flow switch that shuts off power instead. Just curious what other people use when the owner doesn't want any water in the pipe inside the room unless the heat detector trips if you can't use a solenoid?

They are listed for fire protection service as a releasing device for deluge valves used for deluge or preaction applications. It may be used as such when integrally installed as part of an assembly meeting the deluge valve laboratory standards. Regards, Salvatore Izzo, P.E.
