Smoke and CO2 detectors
 
Hi All,

The Allmand 31 is mine! :) The insurance company gave me 45 days to comply with recommended repairs/upgrades from the survey, 2 of which were smike detector and CO2 detector. No big, I'm good with that. I've researched and found we don't have "marine industry standards" for these items and feel OK getting them from Home Depot, but where to install them... never thought about that before. Really can't see punching holes in the overhead so the smoke detector is on the ceiling like in the house. Any suggestions?

They make combination units so you only have to install one.

Diesel engines can leak a small amount of Co2 so you might consider placing it fairly near the engine and galley.

Congratulations!

I think it is a CO detector that they require and they do make them for marine use

They do make marine versions. Unlike fire extinguishers, there is no legal requirement for installing the marine version rather than one you would use in your home. I'm not saying they aren't built differently.

"Sticky" sided Velcro?

They should really be on a 24 hour 12 volt circuit and they kind of fall under UL 2034


I fell it is a small investment and have a SAFE-T-ALERT unit

That is what I use. Mount them in the center of the main cabin.

Double-sided sticky tape (or velcro, but I don't think you're going to take it down much, a battery one lasts for years) for mounting. Remember that smoke goes up high, CO, CO2 (and propane if applicable) go down low.

Double-sided mounting tape, and a BIG patch of it, will work. Most "Velcro" adhesives will release on a hot summer day.

Also be aware the all of the inexpensive smoke detectors are "ionization" types that need to be thrown out, completely, in five years. They tend to die around the 5-7 year range as the ionization chamber gets covered in crud internally, and if you are in a salt air location, I'd expect it to fail even sooner. So look for a "dual" detector, because the photocell type are slower on some fires, faster on others, and the dual detector can sometimes give you a full 15 minutes of additional warning. Figure $30-50 for a dual detector, and keep the CO detector separate. Those also fail over time.
If you aren't really sure of the difference between CO and CO2...take a basic boating safety course with the US Power Squadrons (USPS) or similar. You'll appreciate some of the safety tips, and probably get an insurance discount when you renew.

You definitely want a marine CO detector, not Home Depot, wired into 12V.

The domestic ones alarm when they reach a threshold, while the marine ones calculate an actual dose over time (time-weighted average). This means that a domestic one is constantly going off, when it gets a whiff of CO from your engine or someone else's. My marine one never triggers accidentally.
