A few months ago, one of our smoke alarms…of course, the one right outside our bedroom door, began “chirping” off and on…most often in the middle of the night. My husband was sleeping on the main floor in a recliner after shoulder surgery, so it didn’t bother him, nor could he fix it if it did. Finally, in desperation, I got the step ladder in the daylight, unplugged it and jerked that thing down. After pulling out the battery, I was stunned to hear it continue to chirp. Shortly, it did a rather weak chirppppppp and that was the end of that.
I got on-line and ordered the model recommended for replacement of the ones we had, which were 17 years old and past their prime. When they arrived, I called a local electrician and he came and installed two new ones in a flash. But alas, four nights later, the same alarm outside the bedroom door began chirping, first 4:00 a.m. and then again at 6:45 a.m. That was last night.
The electrician told us they all will chirp and usually in the wee hours when it is coldest. The ones in his house do and they are interconnected. He also said he’s found spiders in them that were the cause, as well as dust. Back on-line to read the comments for the particular ones we have. One man said he found little green bugs inside his that caused the chirping. Others have never figured out what’s making it happen.
Okay, here’s my question, especially for, but certainly not limited to, those of you who are firemen/women. I know there are several in the PSWA group and among my Facebook friends. In your opinion, what’s the best brand/kind of smoke detector to buy? And what’s going on with this chirping with a product that’s only been up four days and was installed by a professional electrician? Ours are hard-wired with battery backup.
For everyone reading this, tell me what brand and kind you have in your house and how they are working. Do they ever chirp? Do you know why? As the electrician immediately suggested, I tossed the cheap “free” battery that came with them into the trash and provided alkaline 9 volt replacements. Lithium is my next purchase. But until I find out what’s making it chirp, it probably won’t matter.
Here is one possible cause, though no problems for 17 years, even when burning a wood-stove full-time in winter. The picture on the right shows where the alarm is located outside our bedroom door, which is right off our loft office. As you can see above the black-backed Chinese Double Happiness emblem the great room is beside and below the loft and the peak of the ceiling is 24 feet. Could that cause a problem?
Someone please tell me what you know and think. Help!
