The side battery drawer slides open for easy battery replacement. A blinking power indicator on the unit confirms that it is receiving power. The silence/test button allows you to both silence a non-threatening alarm and to test the unit's functionality. The alarm contains an optional pin to lock the battery and unit in place for tamper resistance. It can be mounted on either the ceiling or the wall and can be used in mobile homes and RVs. It includes one 9-volt lithium power cell with 10-year battery life warranty. 10-year limited warranty on alarm unit. UL listed for safety. Approved for sale in Oregon.--Bree Norlander

3.0 out of 5 stars Sensitivity Level of These Detectors., November 2, 2007

By	Roadkill "Tasty" - See all my reviews

Amazon Verified Purchase

I bought 2 of these alarms to replace a couple other alarms in my home as they were about 15 yrs. old & thought it might be wise to "update". The long-life lithium batteries was a real selling pont to me. The one thing that concerns me about these new detectors is that aren't nearly as sensitive as my old detectors were. My wife ocassionally burns things while cooking, or gets the oven too hot. My old detectors would "go off" when this happened. These new ones have not signalled when this happens but the old ones still do. I tested the new ones by heating an iron skillet on the stove with a bit of grease in it. LOTS of smoke bellowed out, the old detectors sounded immediately but it took a couple minutes longer and a lot more smoke for the new ones to finally signal. Hope this isn't over-reaction on my behalf but I sort of like the sensitivity level of the older detectors compared to the new ones.

4.0 out of 5 stars No frills, long-life smoke detector, February 16, 2009

By	J. Morris "snowboardjoe" (Durham, NC USA) - See all my reviews (REAL NAME)

Amazon Verified Purchase

I was happy to see this model come out with a long life Lithium battery. I have about 4 of these in my home and it annoys me to have to change batteries at 4:00am to stop the chirping. Installation is simple, detector is loud and easy to operate. Worst complaint is the ugly design as it looks a bit too industrial for indoor use.

5.0 out of 5 stars So far so good, June 5, 2009

By	suaspontemark (Savannah GA) - See all my reviews

After reading that smoke alarms should be replaced every 10 years, and not knowing the age of some in the house, we replaced them all with these devices. They're inexpensive, and if they operate as advertised the lithium battery will cost less than 10 years worth of alkalines. Besides, I get tired of getting out the ladder for the one in the high ceilinged room and with these there's no worrying about remembering to change the batteries. I just wrote the month and year installed with a Sharpie on the one in the basement and we'll replace them in a decade or so.
