The First Alert SA320CN Double Sensor Battery-Powered Smoke and Fire Alarm is equipped to detect smoke particles caused by both flaming and smoldering fires. Fast flaming fires spread quickly and leave minutes, maybe seconds, to react. Smoldering fires burn long and can unknowingly fill the home with smoke causing smoke inhalation. The SA320CN's smart sensing microchip helps determine the difference between non-threatening conditions and real emergencies. This smoke alarm also provides dual sensor technology for maximum protection. While all smoke alarms are designed to detect smoke, different sensing technologies react differently to certain types of fires. This alarm makes use of both ionization and photoelectric sensors to offer the earliest possible warning, regardless of the type of fire.

We ordered 5 SA320Cn fire alarms. They arrived promptly and were well packagec. All were tested with real smoke and fire and alarmed promply after exposure. We were well satisified and are ordering more for our childrens homes.

No nuisance - 07/18/2011
Reviewer: HENRY DWYER
We have a vacation house with a large open floor plan, so burnt toast used to set off the ionization smoke alarm all this time. After carefully mounting this unit so that the ignore button is within reach, we havent had to touch it, after a week of use. BTW, the new mounting setup is really easy if youre not scared by drilling into your wallboard for 2 teensy holes - the unit rotates on the base, so you cant make a mounting mistake.
No more breakfast alarms - 07/12/2011

It seemed like our old alarm went off every time we cooked bacon for a big weekend breakfast. This one seems to know the difference

Great Alarm - 07/05/2011
Reviewer: Jan Kral
This dual-sensor alarm provides the most security for your family because it senses two types of fires, while most alarms sense only one. Easy to test, easy to change battery.

I hope to really verify that my purchase is Very Good or not. I have not yet installed the unit but will in the near future. Thank you, but I do not anticipate making any further purchases from First Alert, and I do not need any more of your reminders.
