Fire Inspector recommended

We recently were awakened by our smoke alarm. Unbelievably, an empty bedroom was ON FIRE!!! My husband was able to put out the fire before the fire dept. arrived. With a First Alert extinguisher. Without that smoke alarm, we would have never known. The fire inspector recommends the dual sensor detectors. So, we got extras. The old one worked, it was dual sensor, too. Please, ALWAYS have one of these AND an extinguisher!

Saved My Birds!!!!!!!!!!!!

I literally kissed my fire alarm this morning. Bought this two months ago to put in my detached building that houses my exotic birds. This morning the heater started to smoke and this alarm detected it IMMEDIATELY! The alarm woke me up (through the baby monitor) and I ran outside barefoot! Luckily, the building didn't even have time to fill with smoke, and you could only smell the smoke on the heater. This fire alarm saved my building and most importantly it saved my beloved birds!! Birds are incredibly sensitive to smoke, so the fact that this thing was able to detect the problem so soon is INCREDIBLE. The alarm was positioned about 5 feet almost directly above the heater. I highly recommend!!!

Top rated dual sensor Smoke & Fire Alarms

I bought 4 of these 10 year lithium battery, dual sensor smoke and fire alarms which were rated #1 by Consumer Reports. Installed easily and hopefully won't ever be needed. I find it very upsetting that the dual sensor alarms are not available in stores, and are only available on line, when they are rated the best for alerting you to fires and smoke which will save lives. They should be readily available in many stores. Please note that they have an inexpensive battery version of this smoke detector, but thanks to a new California law in July 2015 requiring 10 year batteries they are not available in California .

Easy install, great alarm.

Packaging: The three alarms arrived in individual bulk brown box packaging; nothing wrong with that. In the box was the alarm, 2 AA alkaline batteries, mounting screws, and instructions. I am a guy so who needs instructions. The alarm itself was wrapped very well in bubble-wrap. I am very satisfied with the packaging. Installation: Installation was a breeze. You first install the two batteries according to the diagram on the alarm. The new alarms were replacing old First Alert fire alarms that we have had for over 20 years. I now know you should replace alarms every 10 years. I removed the old alarms by loosening the mounting screws a couple turns, turning the old alarm to align the mounting holes and that was that. The new alarm has a base and alarm. The new base fit perfectly over the existing screws from the old alarm. Tighten the screws and the hard part is done. Then place the alarm over the mounting plate and give a 1/3 turn and you are done. Operation: After they were mounted I pushed the test button and each unit gave two sets of 3 beeps. Happy alarms. Observations: I have heard that the alkaline batteries provided last between one and two years. When they do wear out I will be trying Lithium batteries to see if they last longer. I tried Lithium 9V batteries in the old alarms and two out of four had corrosion on the positive terminal after one year. (P.S. the fourth new alarm was a CO2 + Fire alarm). The only time our fire alarms have ever gone off is when my bride has used them as a dinner bell. Alarm goes off = Dinner is done. PBJ for dinner tonight.

Doesn't give false alarms in the kitchen constantly!

I've only had this up in my kitchen for a couple weeks but I had a great example of why I think this (so far) deserves 5 stars. The existing alarm in the kitchen and the one in the living room would go off every time I opened the oven door with a higher temperature, or if toast got a tiny bit crisp, if i opened the dish washer and it let out a poof of steam, or heaven forbid, i should use the broil feature on the oven. I got so sick of silencing them every couple days and they were probably draining the heck out of their batteries from going off all the time. Anyway, I got this one and replaced just the kitchen alarm. It hasn't gone off once with any of the above mentioned things although the old one in the living room has STILL gone off from those false triggers. The other day, I actually burned a piece of toast, like legit smoke was coming from the toaster and the whole house was starting to smell. As it truly should, this alarm went off and dang it's loud! (Sadly, the toast did not make it) I'm happy with this purchase since I now am pretty confident that it's only going to go off when it actually should and not over every other little thing.

It's amazing what 10 years will do to your smoke detectors

Finally got around to replacing the ancient smoke detectors around the house. It's amazing what 10 years will do to your smoke detectors! The testing procedure is clear cut and the design is very modern. I actually will be picking up 2 more of these (already bought 3 of them) as I missed a couple of locations that need replacing.

FALSE ALARM SOLUTION

THE PROBLEM: Like many of you, I had the you-know-what scared out of me in the middle of the night with what turned out to be a false alarm. I called First Alert, and the agent's first question was whether the unit was located near any type of air vent, fan, return grille, etc. Mine was about 6 feet from a ceiling air vent. THE FIX: Apparently any molecule of dust on the sensors inside the unit can trigger false alarms, so his recommendation was to blow air all around and inside the unit using a can of compressed air or a hair dryer on the cool setting. I used the reverse/blower function on my shop vac, and blasted it from the top and sides. BEFORE YOU REINSTALL BATTERIES: Hold down the test/silence button for 10-15 seconds, then proceed to install the batteries. It's back to normal and working/testing perfectly.

More Peace of Mind with Dual Sensor a smoke alarm

After doing some research I definitely wanted a dual sensor smoke alarm which this is. My understanding is that it is more likely to catch different types of fires like open flame vs slow smoldering. We bought an older house that only had one alarm. I decided that wasn't good enough in case that one ever failed we would be in trouble if we ever had a fire. So, I got three of these to add to the house. Installation and battery insertion is very easy. The other question is... do they work? Yes, they do... we were cooking in the oven and food bubbled out onto the oven elements causing smoke. They did there job and went off. But, once I took them outside they immediately stopped beeping. So, they definitely work!

Highly Recommended Dual Sensor Smoke/fire Alarm

We have several of these around the house as well as CO monitors. This was one of the Consumer Reports recommended dual sensor smoke and fire alarm and we are very satisfied with it so far. I used to get the combo smoke/fire/CO a;arm but they require the units to be replaced on different schedules, 10 years for the smoke/fire and 5 years for the CO alarms. I also prefer to change the batteries every year rather than relay on an alarm that has a 10 year battery. That is fine for the CO if replacing it every 5 years but not so for the smoke/fire alarm. I have read reports that the 10 year battery may not last the entire 10 years from the date you install it in your house. I use the Christmas time frame to replace batteries because it seems you are always getting gifts for kids or grand kids that require batteries so why not replace at that time. Also I use the calendar app to remind me each year and don't dismiss it until I have replaced batteries. The dual sensor smoke/fire alarm is very sensitive to smoke and heat so where you place it is key if you don't want to have it going off all the time. I had placed one of these in the hallway outside the second bathroom and found out it would go off if one of the kids was taking a hot shower when the steam coming out of the bathroom would set of the alarm. Moving it away from the entrance solved the problem. As I mentioned above we have had several of the First Alert alarms in the house over the years and I have been satisfied completely with the performance and would recommend them to anyone, whether it be a smoke/fire/CO combination alarm or the dual sensor smoke/fire alarm. Both are very sensitive to what they are built to detect (important as some CO sensors are not as sensitive as others which means they alarm at a much higher CO level).

Installed securely on my popcorn ceiling

Installed SA3210 10-year sealed unit on my popcorn ceiling. Since the base that attaches to the ceiling covers they ceiling I was pretty sure that I would be able to attach this unit to my popcorn ceiling. After finding a spot, I used a wood chisel to remove some of the popcorn where the hole would go. Now that the surface was pretty flat I marked the spot and drilled the first 3/16 hole. I then used the base as a template and chiseled the area for the second hole and drilled that hole too. I pushed the red screw anchors into the holes and attached the base. It is very secure as the screws tightened completely. It tested great, and hopefully I am good to about 10 years. After installing the first one easily, I installed 2 more.
