Replaced Smoke Detectors

[Tom Bender]

We smelled fumes and thought it was the furnace since it had just started. It went away and we could find no cause. It had been inspected and given a thumbs up a few months ago. Decided to replace the smoke detectors (1985 vintage). Got new ones with CO detection. While installing and with mistake that had them bleating for a few minutes the cats went crazy. It seemed to be the voice was more maddening than the bleating. Smart cats I guess.

I'm surprised your smoke detectors lasted that long. The recommended service life is 10 years. When mine hit 11, they started beeping randomly. Replaced all 12 of them. No more 3 AM wake-ups.

The new ones come with an integral 10 year battery. You can't even hook them up to AC power.

I just replaced some yesterday that still has the 9 volt batteries Kiddy brand. My daughters new house has hard wire units in it and one was bad and went off constantly

Just installed 5 AC versions in my son's basement last week, all interconnected with 14-3. Four smoke only, one combo unit. All from HD and with 5 year battery backup. Yea, 90% of their detectors were battery only. I needed them interconnected and inspected during an electrical final.

Several years ago California required CO detectors installed in all EXISTING houses.
