CO & H Sensor


Does the sensor for hydrogen also disconnect the battery charger if it senses hydrogen?

I ask because I was topping of the batteries with water and it alarmed. After that it did not seem to charge the batteries until I turned off the main DC disconnect and then turned it on again.

Thank you.

Are you talking about the CO gas detector above the entry steps? If you are that is for CO and propane and shouldn't have anything to do with hydrogen. All thou some of us suspect the alarm of sounding due to a build up of hydrogen while the unit is plugged in and charging? The alarm shouldn't be able to disconnect anything as it's just a alarm system.

The manual for the LP/CO detector says it will detect a number of gases, but it is not certified for anything but LP and CO. I have set it off by spraying cleaning fluid near it. We have set it off with the alcohol vapor from wine in a slow cooker.

We had several false alarms that I now believe to have been caused by hydrogen gas from the batteries, which are under the step beside the LP/CO detector in our Sunseeker. After some alarms I shut off the LP at the tank but still had alarms. When I removed the battery cover, the detector immediately alarmed. I am sure methane will set them off, and many have blamed that on their dog(s). Of course, guys have been blaming methane on their dogs for generations.
