Fireboy, Seafire or other fire system question

[Singleprop]

I am looking into the different engine room fire extinguishing systems.

Fireboy MA series claims A, B and C fire extinguishing capability.
Seafire claims only B....(as far as I can find out, not sure it is correct)

Does anyone have any info about this?

Thanks

Good question! Their websites just don't address this issue. It looks to me that none of the Sea-Fire or Fireboy systems are very effective against Class A fires (wood, paper, etc.) Both are effective against Class B fires (burning liquids). The C rating just means it won't conduct electricity.
What was interesting is that the FE-241 used by Sea-Fire in their FE series can not be used in an occupied area. The FM-200 (HFC-227EA) used in Sea-Fire FG, FD series and Fireboy can be used in occupied spaces.

Dupont’s “FM-200" is rated ABC.

Seafire uses FM-200.

Gord you are amazing. Were you a research librarian in a previous life?
Note though that Sea-Fire doesn't use FM-200 in all of their systems. Their FE series uses a different chemical, FE-241.

I wonder why you might choose FE-241 over FM-200?
It doesn't sound as safe as FM-200. Maybe it's more effective? Maybe it's cheaper?

Fireboy uses HFC-227EA which I think is the same thing as Dupont FM-200.
