There as a thread already on this subject, but this starts a new one. I have something beeping in my house that will not stop. It beeps every 40-60 seconds for the last several days. It sounds like a smoke detector low battery beep. The beeping is only heard in one large room that is composed of the kitchen and living room. I have done the following: 1. taken down hard wire smoke detectors and removed batteries several days go. Still beeping sound. 2. Completely shut down the alarm system – removed plug and battery in control panel. Still beeping sound. 3. Turned off power for the whole house - still beeps (that isolates the problem to something that has a battery, right?) 4. Removed all batteries at the doors etc. that notify the alarm system that the door is open.Still beeping sound. 5. Removed the microwave. Still beeping sound. But beep continues – help – driving my wife crazy Any idea where this beep may be coming from. Do dish receivers have a battery in them? Any other electronics have a battery? ---

Had a similar problem last year. It drove me batty. Turns out it was a outlet mounted CO detector plugged in right below the smoke detector. Major face-palm action on that one. ---

Is your refrigerator door ajar, perhaps? Some of them beep to let you know. Or perhaps it has a water filter for the in-door water dispenser, and the filter needs to be replaced. ---

And of course, it’s quick and high pitch, so locating it is almost impossible. A few months ago, we thought our security system had failed as we woke up to BEE-BEE-BEEP! every few minutes and we thought the noise was coming from the alarm sounder. After much sleep-deficient lurching about unplugging things and coming very close to taking a hammer to the alarm system while arguing about whether or not the backup battery could supply power and make it beep just by being in the box but not connected, we eventually located a CO detector BEHIND A BOOKCASE. Yes, some fool hid a CO detector behind a bookcase and its battery decided to run down at 3 AM. ---

I had an electric alarm clock that used a 9 volt battery as a back up for power failures. When, after years of use, the 9 volt weakened, the clock beeped. ---

Depending on the level of clutter present, it might be a smoke detector that’s not mounted – one that was previously taken down and put into a box or something with the batteries still in it, and a new smoke detector put in its place. If so, you have now removed batteries from the new detectors mounted in the house, but missed the one hiding in a box somewhere. I’ve seen that before – people find all the in-place detectors, but nobody thinks to look for an old one in storage, or under a pile of stuff somewhere. ---

My husband had an old watch whose battery had just enough juice left in it to beep on the hour. It was packed in a box in the garage and every so often I’d hear a muffled ‘Bee-eep’. One day I finally got a wild hair enough to empty the garage and find the box it was in. ---

Had that happen a while back in a hotel room, and the culprit was easy to find (small room, ya know). It was the alarm sensor on the window. Since you say you have an alarm system, I’d check any window sensors or glass-break sensors and see if they need their batteries replaced. ---

We had a computer UPS backup that started beeping when the battery was getting old and not holding a good charge. Took a long time to figure that one out. ---

I agree with the CO detector problem. If they get bumped, they can lose connection with the AC and the battery runs down eventually. It’s a loud, high-pitched beep that sounds like it’s coming from everywhere at once. ---
