We were cruising along, drawing ALOT of current from the alternator, 400 watts worth of lighting, 1250 wats worth of stereo and the boat lights. Saw batt voltage getting a bit under my safe zone and turned off the 400 watts worth of lighting and about 2 minutes later the fire extinguisher in the engine compartment fired off?? Now it is only about 5 inches from the alternator and im sure it was warm but should it have fired just being warm (maybe hot??)?? Alternator is still working fine. Just need to replace/recharge CO2 extinguisher. Ill have to say im way glad it was not dry chem all over my engine compartment, that would tend to suc

Bob I have never Heard of this I would think it would trip the Breaker before it got super hot. (you do have a Breaker that matches your Alt output right) if you do you shouldnt have anything to worry about. <BR> <BR>I have a Few questions about your Automatic Fire Ex system. <BR>1. What kind of boat is it on <BR>2. What sets it off <BR>3. If it's a Aftermarket kit who installed it and what does somthing like that cost. <BR> <BR>Thanks G"

It is just a regular looking fire ext with a heat sensor on the head like the ceiing fire extinguishers have(temp gets hot enough to melt a piece and it goes off). It came with the boat (monterey) I will surely be putting it back (maybe not as close to the alt this time though). As far as cost goes i hope its not that expensive to recharge or replace it. There looks to be a way to electrically activate it also, couple of wires but they are just cut off like they never planned on using it on this application.

oh yea there is a breaker on the engine (just for the engine-50 amps) and the main has a 90 amp fuse between the battery and alternator but if the alt is only rated to 65 amps then it would never blow the 90 amp fuse. I know i was drawing more power then the alt was putting out so realy i was sucking the battery dry as we were cruising home but shut off the excess load when i felt it was time then after i did that the ext went off???

Us little inboard ski boat guys usually do not get to play with marine fire supression systems like they have on the off-shore boats. In fact, I am impressed that your little Monterey had one. They are really cool. Next thing you know Grant will be installing a full-on Halon system in his rig. <BR><img src="http://www.wakeworld.com/MB/Discus/messages/65921/78149.gif" alt="Fire">

It's a factory option for any Nautique

Hey he called my boat little <img src="http://www.wakeworld.com/MB/Discus/clipart/happy.gif" border=0>

Jeff - so they are! Never seen one installed. <BR> <BR>Bob, sorry about that. Your boat is *huge*! :-) <BR> <BR>Anyone who skippers a small boat (under 30') is not compensating for any other 'shortages'. <BR> <BR>These guys have some cool systems. Billet aluminum heads and polished cylinders. <BR><a href="http://www.interlinksolutions.com/saferace.htm" target="_blank">http://www.interlinksolutions.com/saferace.htm</a>

just found out mine wasnt co2 but it was halon and is not rechargeable due to the atmosphere deal

I looked into a fixed mount extinguisher for my LXI. I found that the melting point for the sprinkler head was much too low (+/- 175*) for a small compartment like any of ours...Engine 200*+, exhaust manifolds 200* +/-, ambient temp (summertime) 90-100* with limited air circulation in compartment. POOF!!! Any questions?

bob 08-19-2003 6:26 PM

Patrick i just found out the activate temp for my system is 212 degrees, 100 degrees c. I am just wondering if i should look into refilling or opt for a new ozone friendly system?? I emailed the co to find out if they can even still refill halon 1301??
