Questions & Answers

mounting of 10 year battery smoke detector

In the rentals I manage, I have first alert smoke detectors. Can the new 10 year non replaceable battery detectors be mounted on the same mount. Or even is the mounting the same size?

where can purchase be made in Cincinnati Ohio for model SA340? What unit can replace SA340 without removing SA340 base?
Asked by: Stephen
Thank you for your recent inquiry with The Home Depot Stephen. The SA340 has been discontinued. We don't recommend using the base with a different detector. Please consider Model# 21009992 by Code One for $19.97 that can be purchased at your local Home Depot store in Cincinnati, OH as a comparable replacement. We appreciate your business and look forward to serving you in the future. Thank you for shopping Home Depot.

Can these batteries be replaced?

If the batteries can be replaced where are they purchased?
Asked by: Pat
Don't believe so. It's a battery pack, not a standard AA or 9v battery. Good for 10 years, or so they say.

Does this smoke detector with 10-year Lithium battery meet the California SB 745? Commencing January 1, 2015, all new smoke alarms or combination smok

Asked by: Ritz
Per http://www.firstalertstore.com/store/products/sa340cn-tamperproof-10-year-smoke-alarm.htm : California Residents - Please Note This Alarm is Not Compliant with California State 10 Year Sealed Battery Alarm Legislation Requirements ... not sure why, though this might explain why it says that they can't ship it to California.

Battery Operated 10-Year Lithium Sealed Smoke Alarm is rated 3.4 out of 5 by 28.
Rated 1 out of 5 by from 10 year battery? So how come they only last 5 years? Perhaps it should be called a 5 year battery.
Date published: 2015-09-12
Rated 1 out of 5 by from bad battery I agree with other reviewers on the battery life. Ours lasted 3 months before the 10-year battery died and the unit started chirping at 5am-- we had bought this unit just so this wouldn't happen for some years. We'll be looking for another more reliable brand, or going back to the replaceable battery models.

Rated 1 out of 5 by from NOT A 10 YEAR BATTERY Installed this "10 year life" lithium battery alarm in July of 2013. It is September, 2015 and the stupid alarm is going off every 15 minutes because of low battery. Took the alarm off the wall and took the battery out. Will replace with another brand. Ridiculous.

Rated 1 out of 5 by from 22 Month Life Purchased and installed in November 2011. I received the "dead battery" beep at 2:00am a few nights ago. We've determined that the 10 year batteries did not make it as promised. Not sure if First Alert backs their products - still researching....

Rated 5 out of 5 by from A great purchase, no more need to replace batteries for ten year It would be better if they like every other manager does use screw holes rather than those wacky slots that you practically need 3 hands to install the base. A number of holes in different location so that it can be properly aligned.

Rated 2 out of 5 by from Battery life too short Bought the original in 2014 but the smoke detector stared chirping like it had a weak battery after only 28 months. Far short of the expected 10 year life.

Rated 5 out of 5 by from worked for 16 years installed mine in 1997. It just failed 2/2013. going to replace with the same one.
