I heard that it changed recently or something but I don't know, anyway I wanted to put one of these on my helmet
Hmm, good questionI would suggest either: 1. Getting a 25 foot ladder (buying or renting); or 2. Call your local fire department for help/advice (a friend of ours had called them for their smoke detector that was located on a vaulted ceiling, and they actually came by to change the battery for them); or 3. See if a paint crew (who usually has very tall ladders) could stop by and change it for you (for some nominal fee).
I wouldn't. I don't want anymore Government in my life. I have not seen one Governmental program that has done what it said it would do. Just another way for Government to get its' hand into our personal lives. Furthermore, our Politicians should really study those health care systems in Europe, as most are trying to get out of the Government run systems since now they are becoming way too expensive. Will our Politicians ever learn? I don't think so.
I hope that a smoke detector installed at that height would be part of an interconnected system of smoke detectors that run from your AC power. It may not have a battery. However, if it does have a battery, you'll need a ladder to reach it. Why don't you install another smoke detector at a more convenient height? It would be closer to the likely source of the smoke, and you'll get an earlier alarm in case of fire. You might need two or more for good coverage.
How in the world did you get it up there in the first place? I have no clue how to change the battery in something so high up. You may just have to buy a new smoke detector and place it elsewhere in your home.
your first problem is having an essential household appliance in an unattainable place, you need to move it. odds are it is in the most inconvenient place, away from any walls or you would have gotten the ladder from a hardware store that rents. so you could always get scaffolding. its easy cheaper than contractors, bugging the fire dept, or trying to figure out how to get a lift through the door
