07 Bounder Alarm

[BLE373]

2007 Fleetwood bounder workhorse w22 chassis 35E.

Storage check found a slow loud alarm beeping constantly in front interior. Sounds like it’s coming from the overhead speaker. And can’t determine what’s causing it or how to shut it off. Everything started right up generator runs AC no dashboard lights.

What could it be?

It can be hard to tell where it is coming from if it is high pitched. First thing to check is the Carbon Monoxide alarm. Find the box and see if it the indicator is red. They have a limited life and expire with the alarm on. Check the expiration date on it. Unscrew and unplug it. Same with the smoke alarm and propane detector.

Thank you all who contribute here.
Just so ya know.
Our 07 Bounder W22 35E was plagued by beeping noise somewhere in front of coach interior near cab while in storage.
Turned out to be the stock radio flashing and making a stereo beeping noise.
Drove us crazy trying to it identify.

Resolution was ultimately pressing the radio rest button.
