Newell Gurus

@"SouthernDevGirl" , almost missed seeing your post on this old thread.

As to the "Head Temperature" for activation, most of the "marine" type of auto-extinguishers will have 175º heads; very few are 225º. But, I'd surely not consider one that's over 300º as you've seen.

For the Gen compartment, Newell installs a small SEA-FIRE FG-125A with the fuel shut-off, which is what you want for a diesel fire suppression system.

@"CaptainGizmo" - Thanks so much, a SEA-FIRE 125A it is, then.

Also, if anyone else stumbles upon this post in a search -- The SEA-FIRE FG-125A appears to be activated at 175º F; the user manual: http://sea-fire.com/wp-content/uploads/2...Series.pdf
