I've always been curious which hallucinogen the person who designed the 9v battery drawer on those things was using at the time.

The ladder is behind 2 cars in the garage, no 9V batteries, and the hardware store doesn't open until 8.  

Beautiful full moon, though. 

 

That is a good one, Ed.

A few months back I had a storm induced power outage. The whole neighborhood was knocked out. About a half hour into it my detectors started going off saying, Gas alert! Gas alert! I called a friend who is a firefighter and he said to call the fire department and have them come out and check it. He seemed concerned. I called the FD and they explained it is probably just the batteries, but they would come out if I wanted. I told them no, not at this time. So, I decided to wait it out until the power came back on.

I go to bed, trying to sleep, but good luck with the detectors doing that every few minutes. Well-- the power kicked in at about 11:30 PM. And guess what? The detectors kept chiming. S O B! Now I have to go get batteries. I hop in the car and try finding a place that was open. There were still some areas with no power, this was not an easy task. I found a gas station that had power, I go in, asked the guy where the 9v batteries are. The guy looked at me weird like I was gonna rob him! He was watching my every move. Maybe that is a line robbers use?  "Hey!  Where are the batteries!  Stick em up!"  He seemed relieved when I forked over the money and I walked out. Lol. Seriously dude. Do I look like a robber? Ok, I didn't shave for a few days but..

I go home and install the batteries. This is no easy task. The dectector upstairs is mounted on a high ceiling. I have a 6 foot ladder and I had to stand on the top step (not supposed to do that) and brace myself against the wall. I am sleepy eyed and not as spry as I used to be. I am praying I don't fall off and land at the bottom steps. Thank goodness the detector didn't fight me as I tried to install it.  I get them all installed and guess what? "Gas alert! Gas alert!

Dang it.  Now what.  I decide -- ok-- lets push the test button. The detectors start chiming on all the floors, talking back at each other. I am thinking... my neighbors are gonna wonder what the heck is going on over there in the middle of the night. After a minute of this-- halelujah-- it stopped. Shaking my head. 

That is what I get for not changing the batteries once a year. The detectors are hard wired but if the power goes out, the batteries kick in. 

THE END

No 9 volts???

Whenever I need an AA battery for a remote or something I have an entire drawer full of AAAs.

Whenever I need an AAA I find an entire drawer full of AAs.

Why did your smoke detector's battery fail at 3 A.M.? Because the Creator likes to play jokes on us! Why did my well pump fail on New Years eve? Why did my house's main sewer pipe get plugged by a dead squirrel on Christmas day? Some one must be enjoying these situations.

Your comments and questions are always welcome.

    Well it sounds like it is working as advertised, make very annoying noise at the most un expected and inconvenient time to alert you to danger. Since it technically is a false alarm....make wafflesWink

we're modelers it's what we do

It's simple.

The ladder is in the wrong place

You didn't stockpile enough batteries to run your alarm and transister radio for the next 20 years

If you had owned the store it wouldn't matter when it opened you would just go get some

Did you set the timer for the battery alarm to go off at a more convientment time or at least send a early warning message to your phone?  If this part was done, don't forget to charge your phone

If nothing else, mark it up to Murphy's law
