Smoke detector going off with no sign of fire?




kdaddy_95


I'm hoping someone can help me, and it's not an emergency. I've got a smoke detector in my basement that is going off. It's near a dryer and near my oil furnace, but there is no visible fire. I know that a shower can make a smoke detector go off. Is there something that I'm overlooking that would cause this to happen?


Answer
First off, if it is indeed a "smoke detector" than rule out Carbon Monoxide, because that's a completely different detector. However, CO detectors CAN look just like a smoke detector, so make sure it isn't a CO detector or you may have anohter problem all together!

If it is a smoke detector, try using the attachments on your vaccum cleaner to suck any dust out of it that may have built up over time. A can of compressed air can also be used to "blow" the dust out. Detectors will often "false alarm" if there is dust built up inside the sensing chamber.

Low batteries do not generally cause a false alarm, but if you haven't replaced the battery in awhile, it's certainly not a bad idea.

Nothing lasts forever. If the detector is older than 10 or 15 years, you may want to consider replacing it with a new one. The battery powered ones are typically about $10, while the hardwired ones will run you about $30.

Good luck.

What can I do about a smoke detector than uses batteries very frequently.?

Both ULI and Kidde detectors installed in my house seem to be eating batteries . The ULI detector was manufactured in 2009. The Kidde one in 2010. ULI says it is warranted for 5 years, Kidde for 10 years. Kidde one has suddenly been false alarming carbon monoxide detected when hard wired. Could the hard wiring need to be replaced? My house was built in 1986. Detectors have been replaced several times over the years. The combo carbon monoxide/smoke detectors seem to have more false alarms and are eating up 9 V back up batteries. Help!


Answer
If the voltage is wrong it could be killing the alarms and they are constantly on the battery hence the reason they seem to go through batteries and false alarm.

You could have AC detectors and your home smoke detector circuit is DC (not good).

You could have DC detectors and the power on the line is AC(not good).

Or the voltage could be wrong it may be 120v ac and the detectors are 24vac. (not good)

Sounds to me like it is time to break out the volt meter and do some sleuthing and them go get the right detectors or rewire the detector power circuit in your home.
