400 CO Detector Chirping Every Half Minute

The camper has been sitting idle for quite some time. It's been on shore power from the house. The CO detector is chirping every 30 seconds or so. I removed the wood floor of the compartment above it, only to see two wires: no fuse to pull. I pulled the related 7.5A fuse from the main fuse box, but it kept chirping. How do I disable it/make it stop?

Thanks.

    I had a similar issue which eventually turned out to be low voltage. But the beeping was occurring in the middle of the night. I followed the pair of wires out the back of the detector until I found a Wago connector and removed the positive power lead.

    Thanks. I am tempted to just remove or snip the positive lead as well. Note that our camper is sitting in a driveway in Phoenix, where hostile sun and summer temperatures probably are causing some outgassing inside the camper. I don't know if that might be what it is detecting.

    The Alarm is trying to tell you something. Low battery? End of life? Actual gas being detected?  Try this page from the RV Safe manual and see what that pattern is trying to say.
    Note the Alarm section that discusses "high voltage" and low voltage.  What battery setup do you have in the trailer?  Are the batteries failing or overheating?

    Well, duh. The chirping wasn't coming from the CO detector. It was the dying 9V battery in the smoke detector. Thanks for help, anyway.
