2011.0. "Fume detector mounting location" by WONDER::BRODEUR () Tue Mar 16 1993 07:58


	I have a simple question about the placement of a control panel for a
gasoline fume detector. I just (finally) purchased a Xintex M1 fume detector
for my boat since I still run with a Atomic 4 gas engine. I'm trying to figure
where to install the control panel which contains the alarm horn and indicator
lights. I'm not sure how water-resistant this panel is but that may not be an
issue. Does anybody have something similar installed in their vessel and if so
where did you mount your panel and why?

	I want to be able to hear the alarm while down below since that is
where I am in most danger. At the same time I would like to be able to here
and or see the panel from the cockpit while underway. The instructions simply
say to mount the panel "at the instrument panel...." Since most of my engines
instruments are under a cockpit seat and VERY difficult to access this does NOT
sound like the place to mount this. Down below near the electrical panel does
not help me while I'm in the cockpit. I have not tested to see how loud the 
alarm is so maybe it could be mounted "near" the cockpit and still provide
protection while down below. I'll probably test it this weekend. Any hints on
where this might want to go would be appreciated.....

If you mount it to a fiberglass bulkhead or coaming that faces the cockpit,
there's an excellent chance that the alarm sound will couple into the bulkhead,
and make an adequate amount of noise in the cockpit. If the alarm is loud,
almost any below-decks mounting should be load enough to hear in the cockpit,
unless the companionway is closed up completely.

    I agree with the prior comments about the noise telegraphing.  
    
    You can also hook up a remote 'sonalert' where ever you want one down
    in the cabin.  A sonalert is not difficult to install.  In case you
    don't know what I mean, a sonalert is a 'horn' which you can parallel
    (electrically) with the current alarm on the unit you installed near
    the instrument panel.
    
    Another factor is that if your engine is RUNNING you may not hear
    the alarm down below.  But if the engine is running someone is
    hopefully going to be in the cockpip STEERING the boat! so they
    should hear it.
