Product Overview

Dual sensor technology is the preferred choice of fire service professionals for its ability to detect both flaming and smoldering fires. Ionization technology smoke detectors are generally more sensitive than photoelectric technology smoke detectors at sensing small particles, which tend to be produced in greater amounts by hot, flaming fires that are consuming combustible materials rapidly and may spread quickly. Photoelectric smoke detector technology is generally more sensitive than ionization smoke detector technology at sensing large smoke particles, which tend to be produced in greater amounts by smoldering fires, which may smolder for hours before bursting into flame. With this fire alarm, you no longer need to choose just one technology. This unit is powered by 2-AA batteries (included), and features intelligent sensing technology which reduces non-emergency or nuisance alarms. This product is also backed by a 10-year limited warranty.

  • 2-smoke sensing chambers, ionization and photoelectric for maximum fire detection
  • Intelligent sensing technology reduces non-emergency or nuisance alarms
  • Single button silence/test mutes unwanted alarms
  • Operates on 2-AA batteries (included)
  • 10-year limited warranty

I'm finding that some alarms don't audibly notify you when the batteries are dying or dead. Does this model?

If it's fine to use rechargeable batteries, do they have to be a particular type (e.g. made out of NimH), or are there any types that should be avoided? Any info would help. Thanks.

I have heard and read over the years that using rechargeable batteries in smoke alarms is not recommended. I don't know why this is. I have used rechargeable NiMH batteries for years in my previous smoke alarms with no problems. I know they still worked(detect smoke) because they sounded off on a few occasions due to smoke being generated from cooking. Since this smoke alarm came with "regular" batteries, I am using them until they wear out. Then I'll probably go back to the rechargeables. I would think any type would work. I don't think the smoke alarm knows(or cares) what type of battery is supplying voltage to it. Read Less

Answer: 
Yes, rechargeable batteries will work fine. As to the type, I would avoid using Lithium Ion as they have some very different properties than other types and may not give you much warning when they get weak.

Answer: 
I would think ten year lithium batteries would work fine. I have only battery operated smoke alarms. If you mean would the mounting bases for First Alerts and Kiddes be the same, I'm not sure. I doubt that they would be compatible. Each manufacturer generally designs their products in their own way with no concern for compatibility being shown for other competing manufacturers.

Answer: 
No, both my dual smoke detectors are battery.
If your item is battery operated, you can use any type of battery you choose: however, if it is both hard wired and battery backup, then you need to determine if the battery is kept in a charged state by the A/C. If so, any battery you use must be a rechargeable type. Your literature should tell you this.

You should be able to use the existing wiring for the Kidde smoke alarm. As long as you completely remove all the Kidde circuitry. Be sure to disconnect the power before attempting to disconnect the old alarm and check with a volt meter before continuing.

Rated 4.7 out of 5 by 57 reviewers.
Rated 4.0 out of 5.0 by Great value Very good product for the money ; have had these previously and they last several years. August 28, 2016
Rated 5.0 out of 5.0 by Nice Easy to install even without reading the very small print instruction. No false alarms yet after install 2 months ago. August 2, 2016
Rated 5.0 out of 5.0 by Well made smoke alarm So far no false alarms or fires, so I can't really talk to how good it is at alerting on fires. It seems well made and was easy to install. I like the fact that the batteries can be replaced without taking it down. I also like that it uses AA batteries. July 12, 2016
Rated 5.0 out of 5.0 by So far good Easy to install and so far no problems. Installed in garage and time will tell if how it functions; has only been installed for a month. July 12, 2016
Rated 5.0 out of 5.0 by Excellent Smoke Alarm Bought two smoke alarms as a gift to my son for his new house. Consumer Reports rated the smoke alarms very high. Great price and delivery to near by Home Depot was within 5 days. May 17, 2016
Rated 5.0 out of 5.0 by Excellent Product! Very reasonably priced as well! I work for HD and this is the smoke alarm I ended up buying. I did alot of research on smoke alarms before purchase. Recommended having both types of sensing technology for the best protection of either smoldering or raging fires. This alarm has both. Now, it doesn't have a "10-yr." battery so you'll have to change out battery every 1-2yr. It also may be sensitive to "false" alarms (which I have not experienced yet.) I, personally, will take function over convenience. This product, IMO, should be offered in the stores. Just order one on line and it will arrive in the store in no time. Just make sure you select the right store # on the top of the page. January 20, 2016
Rated 5.0 out of 5.0 by Very pleased.... I especially like the fact that you can change the battery without taking the unit down. April 5, 2016
Rated 5.0 out of 5.0 by One of the best Dual Sensor Photoelectric and Ionization Smoke Alarms are the only type I buy. They cost a little more, but how can you put a price on you and your families lives. When my family is sleeping, I want to know as soon as possible when I have a smoldering fire or a flash flame fire. This is the detector that does both. I just put a small nail in the wall about 6 inches from the ceiling and hang the detector on the nail. This way I can just reach up, take it off the wall to change the battery. February 13, 2016
