The CO alarm likes to go off while I'm taking a shower. I was told it was because of low voltage.

I've been pulling the fuse for the alarms while I'm in the shower so I don't have people busting into the camper to "rescue" me while I'm buck naked.

Last weekend I camped with SHORE POWER for the first time.

Even with the converter's help, the CO alarm started chirping as soon as I turned on the water pump.

Any ideas what's going on?

Is there any chance water vapor from your shower is getting to the alarm?

We have a smoke detector located close to one of the bathrooms in our house, after several years of service the alarm sounds whenever we take a shower.

Running the vent fan in the bathroom eliminates the problem. I'm not sure if CO2 alarms can be sensitive to water vapor, anyway if your not running the bathroom vent fan when showering you might try turning it on and see if it helps.

With all the problems you are having with the CO alarm, I would just get a new one. You don't want one that might NOT work on a legitimate event.

Your CO detector is hard wired for power?

CO alarms only last a limited period of time. I think it is 5 years. I had one that was erratic. I found it easier to replace although there is supposed to be a way to fix them. Cleaning didn't seem to help.

Recently had the alarm issue as you describe.....Mine was a low voltage issue and once I had the batteries checked out and replaced both (only 1 had a problem)the alarms quit sounding off.

Both detectors (propane, and CO/smoke) are hard-wired into one of the converter's 12V circuits.

As soon as I turn on the pump to build pressure, the detector starts chirping.

Both detectors are originals that came with the camper. I should just replace them with 9V battery powered models and be done with it.

12 years old? think replacing would be good. Actually now that Im think about it our LP detector is original, its hard wired. I was unaware of hardwired CO detectors. Thought, like most smoke detectors, battery powered. Ive only seen hardwired that had battery backup on co/smoke detectors
I would still change out but wonder why pump triggers detector? Or failing detector more sensitive to low/fluctuating power. I know our pump caused our incandesants to flicker.
