Featuring state-of-the-art technology that provides you and your family with an early warning of household fire, the First Alert SA720CN Photoelectric Sensor Smoke Alarm with Escape Light is an effective device designed to be the first line of defense in your household's fire-safety plan. This UL-listed alarm detects the presence of smoke and fire, while also providing a source of light to help guide you safely outside.
Smoke Alarms: 1 in every bedroom and at least 1 on every level of the home.
Carbon Monoxide Alarms: 1 on every level of the home and 1 in each sleeping area.
Fire Extinguishers: 1 on every level of the home and 1 each in the kitchen and garage.
Where does carbon monoxide come from?
Fire is a serious threat to every household; it can strike anywhere, any time. The frightening truth is that in 2005, there were nearly 381,000 home fires in the U.S., resulting in over 16,000 casualties. Thankfully, smoke alarms like the SA720CN help to reduce the risk of death in a household fire by up to 50 percent. The more smoke alarms you have installed in your home, the higher the chance you'll be alerted to a fire in time to escape.
Smoke/Fire Detection and Escape Light Get You to Safety
The SA720CN smoke alarm alerts you to smoke and fire with a loud 85-decibel alarm. An escape light located right on the unit activates with the alarm and helps you see the path to safety. Many mistakenly believe that fires burn bright enough to sufficiently illuminate enclosed areas. In truth, fires often burn very dark, making it difficult for you to see a clear path out of harm's way. That's why the escape light is so vital; it provides the necessary illumination you need to get yourself and your family outside as quickly as possible.
Innovative Photoelectric Sensing Technology Detects Even Slow, Smoldering Fires
The SA720CN alarm uses photoelectric sensing technology, which is generally more sensitive than commonly used ionization technology, to detect large smoke particles. Large smoke particles tend to be produced in greater amounts by slow-to-burn fires (often caused by cigarettes burning in couches or bedding), which may smolder for hours before bursting into flame.
An added bonus, photoelectric sensing technology reduces false alarms like those caused by cooking smoke and shower steam.
As easy to operate as it is effective, the SA720CN boasts patented OptiPath technology, which provides 360-degrees of direct access to the smoke sensor. Additionally, a mute button quickly silences false alarms for up to 15 minutes and also doubles as an alarm test button.
Advanced Features Test, Protect, and Monitor Battery Power
Because smoke alarms are only as effective as their batteries, the SA720CN comes equipped with features that protect its battery (included) and make it clear when the battery needs replaced.
First, an easy-access side battery drawer makes it a snap to change the battery without removing the alarm from the wall or ceiling. A blinking power indicator confirms that the unit is receiving power, and an alarm will chirp once per minute when the battery needs to be replaced.
Additionally, a battery-guard drawer resists closing unless the battery is inside, and an optional theft-prevention lock secures the alarm when activated, so that the battery and/or alarm cannot be removed without proper tools, preventing children or others from compromising the alarm's ability to detect smoke and fire.
The SA720CN comes with a 10-year limited warranty.

The general consensus was; any smoke detector is better than none.
To use both types is best. But if you're going to buy one, get a photoelectric. So I looked on Amazon and decided on this one because; the features - photoelectric sensing and the escape light. and the price was very reasonable. I bought 2 in November for $15.51 each on Amazon.
Sometimes you will see one that looks similar except it's $10.00 more & states on package "10 year battery life". It's not a better detector, It's $10.00 more because it has a 9 volt lithium battery, which you can buy at any drug, hardware, or home center store if you choose to. And also when I first opened it, I noted that it is was really well made. Not flimsy like ones I've used in the past. I highly recommend this detector and hope this was helpful to someone.
Photoelectric is much better than ionization (Americum) units. For one those radioactive units can leech low levels of radioactive isotopes into your home. This was designed as a cheap disposable way for the nuclear industry to get rid of radioactive waste - in your home. Also Ionization detectors are known to be ineffective for MANY kinds of common household fires. Photoelectric is best for slow burning - typical house fires, and good for flare ups. House fires tend to smolder before bursting into flames. These photoelectrics will kick off earlier than ionization ones for this reason.
Remember, the photoelectric sensor only lasts about 10 years. Replace them every decade! Be sure to use a permanent marker to write on the inside the install date so you know when to dump them. Since you probably purchase them at different times, some are newer, some are older.
Never realized there were two types of alarms... Photoelectric and Ionization.
Photoelectric models (also called photoelectronic) are best for bedrooms and living rooms. These rooms contain large pieces of furniture (sofas, chairs, and mattresses) which burn slowly and create more smoldering black smoke. They resist steam false alarms well also.
Ionization smoke alarms work best for flaming fires. Flaming fires burn extremely fast, and spread rapidly. They also generate large amounts of heat with little smoke. They are best for rooms which contain highly flammable materials, such as newspaper, paint, cooking fats/grease, cleaning solutions and other flammable liquids.
Kitchens are kind of a problem. They contain a combo of steam, cleaning supplies, hot cooking fats and grease, and have high false alarm potential. I have seen recommendations for both types in the kitchen, but I have had good luck with the photoelectric in the hall just outside my kitchen (I always run my range fan to vent the excess steam/smoke out the roof, ...not that I ever burn anything ;-)
After reading many sites, for maximum protection every home should have both types. The more expensive alarms have both types of sensors built in (but of course that wasn't ideal for my situation).
