I've got one of Jim Bound's small automatic fire extinguishers for the generator compartment.
It's the kind with the automatic head mounted on the bottle. Where have folks been mounting these?
I know the genset gets REALLY hot on top since that's where the exhaust manifold runs, so
I'm worried about it going off during normal operation.
Anybody clues on where best to mount the thing for the generator? I was kind of thinking
more toward the battery end with the head pointed at the top of the genset.
Also, for the engine compartment, it looks like the air cleaner creates an obstacle for coverage.
Any thoughts on the best placement there?
thanks,
Karen

I have not gone over everything Jim offers, but one of the listings that I saw had the deployment temperature too low for me. It was something like 150 or 160. All I am suggesting is that you check what the deployment temperature is on the one that you have to make sure it will not go off unexpectedly.
I am looking for an AR-AFFF extinguisher that will not freeze and will auto deploy somewhere over 275 degrees F. I found out that there is AR-AFFF available that will not freeze until well below 0 F. My choice for placement will be with the sprinkler head towards the front of the coach. I feel the the most important areas that need to be covered are those areas with fuel present (carb, fuel lines, and fuel pump) Ideally you would like to flood the entire generator compartment, but in case it does not do it I want to make sure fuel areas are flooded.

Just make sure that the one you have is a 286 degree one. It gets real hot inside the generator compartment at times and I would hate to see it go off when you do no want to. Now if you were putting one in the refrigerator compartment then the 165 degree one ought to be just fine.
I believe that Jim B. is marketing his products any where he can get them sold and still maintain his profit margin. He is definitely filling a need in the RV industry. Amazon would be a good outlet. Amazon takes the orders and Jim's company ships them direct. I believe that he is also selling them in to boating market.
I would get them from Jim K. or Jim B. I bought a whole bunch (around 60), AFFF ones made by Kidde many years back. I bought everyone I could find. They were on closeout as Kidde quit making them in the size we wanted. These were not automatic deployment ones. Many GMCers now have them in their coaches.
As a favor to me a local fire chief reloaded mine with AR-AFFF. AFFF is OK for gasoline fires up to 10% ethanol (E-10). Anything over 10% requires AR-AFFF. Around here the fire department uses AR-AFFF for vehicle fires. It does a better job in putting out E-10 vehicle fires.
I have been trying to get to the fire chief at one of the local steel mills. Their mill uses a version of AFFF that will not freeze. Some of their extinguishers are mounted outside all winter and are still usable. If I could figure out exactly what AFFF they are using, I would reload mine again with that version of so the extinguishers do not need to be removed from the coach in the winter. That AFFF along with automatic deployments would be a real selling point for RVs that see freezing temperatures.
We had a parked RV catch fire near here 2 winters ago. They think it was initially started by a 12 volt battery electrical problem. It had batteries wired in parallel. The batteries were disconnected from the coach but not from each other. Needless to say, by the time the fire was discovered and the fire department got there, nothing was left to be saved in the coach. I do not know if the coach had any automatic fire extinguishers in it. I doubt it.

It sounds like you are OK with those three extinguishers that you have. You might call one of the Jims and ask if you should use a lower temperature one in the refrigerator cabinet. I have never talked to them about what they are recommending. The higher temperature ones (286 degree) that you have are what I would use around the Onan and main engines.

Karen,
I cannot recall as to where to mount the tank and the remote head, but will find out for you as I have sent email requesting it from FireFight
