Where does carbon monoxide come from?
Smoke Alarms Save Lives
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.
