CO/Propane detector

If the trailer has been sitting for a while, you may have been getting a low-voltage alarm based on battery condition. As soon as the battery charged a little, the alarm condition went away.

The trailer was plugged into 120 volt at the time. The battery shows a full charge.

Was it always plugged in to AC power OR did you just plug it in when getting ready?

Battery shows 'full charge'.........those panel indicators will always show full charge when plugged into AC power.

If you just plugged it in when getting ready......agree that low battery voltage was cause of alarm and then as battery voltage increased from charging alarm reset.

This is a combo unit (CO & Propane)?
Always thought 'propane' detectors were installed down floor level and CO detectors higher on wall due to the way the vapors collected......hummmmmmm :H

I have seen combo CO/Smoke detectors but not CO/propane detectors.

Sounds better than mine last year. It went off (Propane detector) and would not go off. I was on Shore power and had a couple days of my trip left. It went off for a steady 20 minutes until i could take it off the wall and cut the power to it. Now i have to buy a new one before my trip in a couple weeks.

It was always plugged in. I'm fairly sure it is a propane CO unit. Mounted near the floor. I was purging all the air out of the hot water tank at the time. I had the kitchen tap open (hot). It is fairly close to the detector. Not sure if fumes could be trapped in lines & tank could set it off. I just checked again & it seems O.K. now.

Carbon Monoxide is lighter than air, this means that it will float up towards the ceiling. CO detectors should be mounted on the ceiling or high on the wall. Propane is heavier than air and sinks to the floor. That's why propane detectors are mounted at floor level. I'm sure you have a propane detector there.

OK Thanks. Propane wasn't on. May be a faulty detector.

They do make combo LP/CO detectors: I installed one in mine last year after my propane detector failed due to water infiltration. It has led's to show wether it is alarming for propane or CO.

Dual LP/CO detector & alarm

Mine will go off sometimes when I am having the propane tank filled. It also went off a couple of months ago when I dropped a bottle of wine on the floor right next to it!! I guess it didn't like cheap wine.

CO is slightly lighter than air at room temperature (CO is only 3 percent lighter than breathable air). Due to air currents, CO mixes with air similar to perfume.

NFPA 720 2012 edition 9.4.1.2 says standalone and multiple station household CO detectors should be mounted on the ceiling, wall, or other location as specified in the manufacturers instructions that came with the unit.
