PRODUCT OVERVIEW

Model # SA320CN

Internet # 202788788

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 chose 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.

  • Two 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

CUSTOMER REVIEWS

Rated 4.7 out of 5 by 26 reviewers.
Rated 4 out of 5 by This product needs to be in stores As a retired firefighter and home fire safety educator, I am dismayed at the lack of quality fire/smoke detection products carried in-store. This particular unit is a dual sensor, meaning it can detect smoke/fire in two different methods, thereby giving a homeowner a greater level of security. Nothing beats an overall fire safety plan, but fire/smoke detector units like this are a big key in that plan. As for the detector itself, I like the fact that it uses AA batteries and is very easy to install. If you haven't replaced the fire/smoke detectors in your home within the last ten years, you NEED TO DO SO! Technology changes and the newer models are much more efficient than older ones. Remember, the life you save may be yours or your loved ones! July 9, 2013
Rated 4 out of 5 by Good product Don't know about longevity as we replaced for home sale but works great and fire dept was happy. Shipping was prompt and order came through as expected. September 2, 2014
Rated 5 out of 5 by Great product Needed to replace 2 smoke alarms in my home. I looked online and since Home Depot is my source of choice , tried the website. Free delivery to my home saved a trip to the store. Great product - easy to test since the batteries are already installed. Both worked perfectly in test. Extra easy to install - fit into the same place the old ones were. I feel much more secure knowing that I have 2 new smoke alarms. thank you!! December 9, 2014
