timaz996 Posted February 21, 2023 Share Posted February 21, 2023 (edited) I just replaced a 12 V powered propane alarm in my kitchen. Ever since then, when I turn on the aqua hot, the power goes away from the propane alarm. And the first time I turn on the aqua hot, I have to rock the switch on off and back on for it to fire. Another thing, when the Aqua Hot is off. My propane detector will chirp about every three minutes and is on. I guess I need to start taking panels apart in the bottom of my kitchen slide. Does anyone have any idea what would cause this? Tim Edited February 21, 2023 by Tim-AZ Link to comment Share on other sites More sharing options...
BradHend Posted February 21, 2023 Share Posted February 21, 2023 (edited) Interesting. What happens when you remove the new smoke detector? Was this a linkable smoke detector that had an extra lead? Is it polarity sensitive or anything? Chirping every three minutes is commonly due to the backup battery being too low or not installed Edited February 21, 2023 by BradHend Link to comment Share on other sites More sharing options...
vito.a Posted February 21, 2023 Share Posted February 21, 2023 Check your house battery voltage with the inverter charger turned off. 1 Link to comment Share on other sites More sharing options...

I have 800 amp hours of lithium batteries and the voltage rarely drops below 13 volt. 1 hour ago, vito.a said: Check your house battery voltage with the inverter charger turned off.

Happycarz Posted February 21, 2023 Share Posted February 21, 2023 Put a voltmeter across the detector. The kind of leads that pierce the insulation would be great. Now you see what your detector sees, voltage wise. Is it correct? Next is turning on the AH and watch the meter. Let’s catch it in the act of misbehaving. 1 Link to comment Share on other sites More sharing options...
timaz996 Posted February 21, 2023 Author Share Posted February 21, 2023 Update: It's fixed! Thank you to everyone who replied. The propane detector ended up being wired to a wrong ground wire...different circuit I guess...But not by me LOL. There was another ground wire that even had a un-used connector end on it. I checked that ground and the power wire and it had 13.2 volts with the aqua hot on. so all is good. Tim 3 Link to comment Share on other sites More sharing options...
