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.
Sometimes a fire can smolder for hours before erupting into flames. Photoelectric Sensing Technology is more sensitive than Ionization Sensing Technology at detecting these sorts of smoldering fires, like those caused by cigarettes burning in couches or bedding.
Other fires erupt into flames quickly, like kitchen grease fires or fires fueled by paper burning in a wastebasket. Ionization Sensing Technology is generally more sensitive than Photoelectric Sensing Technology at detecting these sorts of flaming fires.
Loud Alarm and Reliable Construction for Peace of Mind
The loud, 85 dB alarm gets your attention quickly, so you can get out quickly or contain a minor fire before it spreads. Plus the smart dual sensor helps the detector recognize the difference between non-threatening conditions and real emergencies, so false alarms are minimized.
This smoke detector meets the UL 217 standard for dual-sensor home smoke detectors, which means that it has passed tough quality-assurance tests and can be depended on to offer reliable protection.
Remote Mute and Easy Battery Access for Safety and Convenience
To mute unnecessary alarms instantly, you can simply point almost any household remote control at the detector and click mute--whether the remote is for your TV, stereo, DVD player, or another appliance. The convenience of this feature means that something as simple as burnt toast never tempts you to take the battery out of your smoke detector and create an unsafe situation in your home. The mute button can also be used to test the alarm function, helping you ensure that your home and family are always protected.
This smoke detector is powered by a standard 9V battery (included). And, because a smoke detector is only effective if it is properly maintained, you'll appreciate that the EZ access battery door means there's no need to remove the alarm from your ceiling when it's time to change the battery.
This smoke detector's neutral, white finish blends in with your décor, and the unit measures just 5.7 x 5.7 x 2.8 inches. It is backed by a limited 10 year warranty.

Top Customer Reviews
Installation is incredibly easy. The smoke detector separates from the base with a light twist (not the usual yanking or bending that always has me convinced I'm about to break the thing). The mounting base is really light, which is nice when your standing on a chair and pressing it to the ceiling above your head. There are two long channels for placing the two screws that hold it up, which gives you a decent amount of error margin. If you're replacing an existing smoke detector, sometimes you can even use both original holes.
First Alert also put some thought into battery replacement. The battery compartment is a dedicated slot that swings out from the side. It's easy to open and close and keyed so it won't close properly if you put the battery in backwards. Although the battery is a standard 9V, the smoke detector uses pressure clips (like you'd find with AAs) rather than the standard snap-in design which requires more forcing.
The remote silencer/test feature is great. Basically you hold down the volume or channel controls from your TV remote to silence or test the detector. This makes this smoke detector ideal for kitchens and rooms with high ceilings since you can silence it without having to get out a stool.
One drawback of the remote feature is that if you have a bedroom or kitchen with a TV in it, you probably shouldn't buy this smoke detector for that room. Before we installed them, I had the detectors on a side table in the living room and managed to accidentally set off their test modes while using the remote to operate the TV.Read more ›
The image shown here is either an old version or just the wrong version. In actuality, these detectors are much better looking. they are actually very round or domed. They also are rather tall, hanging lower from the ceiling than some. I don't mind since they don't look bad and they're rated well. You should check First Alerts website if you want to see what these really look like and haven't seen them.
The other detector that is rated similar to this is a Kidde Nighthawk brand. But it's reported to have more false alarms so I went with this one. I like the looks of this First Alert better, but that's just my opinion.
The photoelectric sensor uses a beam of light that sets off the alarm when broken by smoke. hence the term "smoldering". The ionization sensor is for the detection of flaming fires.
I think you'd have less time to react if the flames are already shooting that's why I like the idea of having a photoelectric cell. If a small fire starts, some smoke would be given off and set off the alarm before it got really big giving you hopefully more of a warning and more time. At least that's what I believe.
If this is in the kitchen as is mine and if you cook without a range hood drawing the smoke this detector would go off. If you toast on the dark side without a range hood pulling some smoke the detector would go off. I don't think of those as false alarms I think it's a testement to the sensitivity of the photoelectric detector which I like.
The alarm is quite loud.Read more ›
