Propane Detection System Survey

[Maine Sail]

Hi All,

I am re-wiring my boat and will need a new propane detection system. I currently have a Safe-T-Alert model and it appears to be kaput. Before spending money on a new sensor or sending it out for repair I figured I'd pole the crew.

Here are my questions.

1- What propane detection system do you have?

2- Is it reliable?

3- How do you know it is reliable?

4- Have you tested it any other way than just hitting the test button to know whetehr it is actually still sensing propane?



For brands I know of Xintex, Trident and Safe-T-Alert, any others I missed? I want the LP panel in the galley with an on/off switch for the solenoid so my wife does not have to go to the main panel when she is done with the stove and the Safe-T-Alert will not do this..

So before I plunk down my $$$, what's been reliable for you?

P.S. Sorry, I know, propane detection is boring stuff but we all need it.....

I stick my nose in the bilge. My entire system is manual. Turns on at the tank and has a test gauge on the high pressure side. Same as at home.

I have the Safe-T-Alert (rectangle panel) and I have performed the tests as outlined in the book. Other than the test button, I think that there is another test where the sensor is removed.

However, since you bring up the subject, I think I will do a real propane detection with a bottle of propane from my gas grill. I would think that a very small amount near the sensor would be sufficient for a test. Or maybe there is an aerosol product that is designed to test these units without releasing any actual propane. I'll check into this.

Perhaps your poll should be who has a detection system and who does not. I'm still using my OEM installed system (24 years old) and it only has a solenoid switch near the main panel to shut off the gas. I always keep the tank off when not in use and the switch off, but now you have me worried that a leak while operating could cause an explosion. It seems like you would smell it but perhaps not. I need to replace my stove (big money) and solenoid switch ( sill works but outside is corroded) and since I don't use my oven have been thinking about an Origo two burner on a gimbal with a microwave below it. I never use my oven, rarely at home either, preferring stir fry and other cooking methods.
I am worried about your waterline however. With all these detectors and extra wiring and extra batteries and spare parts for all of it and tools to replace it, you must be halfway up to the rail by now :>). I know this is an important safey item but at what point was it added to new systems and is it a nice to do or a legal requirement?

When I had my 10-year insurance-required survey in 2007, they required that I install a propane detector. In 1997 one of these was not standard equipment.

They also wanted a bilge hi-water alarm installed and CO detectors.

Had a Xintex on my live aboard 10 years ago. Not reliable then, false alarms whenever it smelled diesel fuel. No current info. Had CNG on last boat. Loved it except for the 300 mile round trip to fill up. PO of present Hunter 37 had bought one (Xintex) but not installed it . PO put propane tank in a bracket on lifeline stanchion, led hose in thru engine vent clamshell. Proper locker in lazarrette is high on my summer to do list. Will face up to alarm question then.
