3 Pack of First Alert Smart Dual Sensor Smoke Alarms with Nuisance Resistance
Smoke Alarm w/ Smart Sensing Technology and Nuisance Resistance
The First Alert SA320CN Dual-Sensor Smoke and Fire Alarm provides early warning of both flaming and smoldering fires. Additionally, its intelligent sensing technology is designed to cut down on nuisance alarms from cooking smoke or other common false-alarm triggers. A single button both silences and tests the smoke detector for simple operation. The battery-powered fire detector can be easily installed anywhere without wires.
Dual Sensors Detect Different Types of Fires
The First Alert Smoke and Fire Alarm comes equipped with two different sensors to offer the earliest possible warning of a fire. The ionization sensor detects flaming fires, such as grease fires or wastebasket fires, and the photoelectric sensor detects smoldering fires, such as when a lit cigarette ignites clothing or upholstery. Both sensors work together to provide comprehensive smoke and fire detection.
Smart Sensor Minimizes False Alarms
People sometimes disable a fire detector when it goes off due to cooking smoke or steam, even though in doing so they endanger themselves and their loved ones. Intelligent sensing technology in the First Alert Dual-Sensor Smoke and Fire Alarm is designed to distinguish between real fires and nuisances, reducing false alarms significantly so there is never a need to disable the alarm.
Battery-Powered Fire Detector Installs Anywhere
The battery-powered fire detector can be installed anywhere with no wires or electrician required. A low-battery indicator light and audible chirp let you know it is time to change batteries. The battery compartment opens without the need to remove the alarm from the mounting bracket, making battery replacements quick and easy.

* California and New York Residents - Please note this alarm is not compliant with your state's 10 Year Sealed Battery Alarm Legislation Requirements.
Ionization smoke alarms are designed to quickly identify fast flaming fires. These fires can be categorized by their ability to generate and combust at an advanced speed (i.e. kitchen grease fires or fires fueled by paper burning in a wastebasket).
Photoelectric smoke alarms specialize in detecting slow smoldering fires. These fires can be categorized by their propensity to produce large smoke particles that can smolder for hours before bursting into larger flames (i.e. fires caused by cigarettes or candles burning on couches or bedding).
For maximum protection and full coverage from both types of fires, First Alert Dual Sensing Smoke Alarms offer elite protection with their photoelectric and ionization sensing capabilities.
Other reasons include: It could be a different device or appliance such as a security system, monitor, carbon monoxide alarm, or other device which has a similar low battery or alert signal. Some of the same factors that cause unwanted alarms can cause intermittent alarms: dust and insects in the alarm or power interruptions in hardwired alarms. Improper wiring on AC or AC/DC smoke alarms. AC alarms will chirp every 5 seconds if the interconnect wire is grounded. The orange interconnect wire should NEVER be grounded; it should only be used to interconnect other smoke alarms or compatible devices.
- You may not be holding the test button down long enough. Try holding it down for up to 10 seconds (20 seconds on photoelectric models) .
- Your battery may not be installed properly or snapped all the way in place. Even if the alarm sounded briefly when the battery touched the terminals, you still need to make sure it is snapped securely in place. If the battery is loose, in cannot power the smoke alarm properly. After installing new batteries, be sure to test your smoke detector.
- Your AC power may not be on. AC and AC/DC units will have a power indicator light (red or green) that shines continuously when they are receiving electrical power.
- If you have a 10-Year model, the smoke alarm may not have been properly activated. If the tab broke away before the alarm was activated, you can use a toothpick to move the switch over to test the alarm.
- There may be insufficient battery power, try new batteries.
- Problems with voltage or insufficient electrical power (brown out) may cause a continuous weak sounding alarm. For AC or AC/DC models, temporarily disconnect power at the service panel until the brown out is over. If you do not restore the AC power, your smoke alarms cannot warn you of a fire.
- Incompatible warning device. If an incompatible alarm or auxiliary device is linked into a series of AC or AC/DC smoke alarms it may cause the system inadvertently go off.
- It is possible that your smoke alarm "silence" button was pushed by mistake. The alarm will now "chirp" once a minute for up to 15 minutes before resetting.
- Are you sure it's the smoke alarm? Funny to ask, but other devices have similar low battery chirps or warning tones.
- Your "new" batteries may not be fresh. If batteries are stored, especially in cold areas like refrigerators, they lose their charge more quickly. Always check the freshness date on the package when buying new batteries. Keep plenty of replacement batteries on hand so that you are sure to always be protected by your smoke alarms.
If it's time to replace your alarms, consider the NEW 10-Year Life series and never have to worry about a battery replacement for the life of the alarm.10-Year alarms are available in smoke, carbon monoxide and combination alarms.
