Fire Alarm
 

DANG Fire alarm kept going off, took battery out, still going off.....found this article and fixed it.....Priceless....

Chances are (believe it or not) when you replace the battery it will still keep beeping. I found this out the hard way. I had to call the company to figure this out. So you know, mine are hard-wired into my house to.

So, what you have to do is the following.

1) Remove the unit from where it's located. Usually turn it and then it can be removed from its holder.

2) Disconnect the wire harness (only can be plugged in one way)
3) Remove the old battery.

(4) This is the key part....depress and hold the test button. You will hear a trailing-off beeeeeeep. Hold the button until you can't hear a single sound.

5) Now put the new battery in.
6) Put the wire harness back in and place it into its holder.

(done)

Why these companies make these things work like this is beyond me. I'll never, ever have a First-Alert smoke alarm again...and I'll never have it hard-wired into my house either. Not only that but I test all the batteries I take out of these alarms and they are all at 9V! So why is the battery dead at 9V?! It's ridiculous.

I'm smart enough to replace the batteries in a timely fashion.....all I need it to do is beep if it smells fire, I don't need it to drive me insane with Toys-Я-Us engineering

I had an alarm that kept beeping even after I changed the battery. I found out that these alarms have a life expectancy of around 5 years or so which I was not aware of. I got a replacement alarm at Ace Hardware and no more problems. I had been living in my house for 5 years.
