First Alert Wireless Interconnect Battery Operated Smoke Alarm with Voice Location Twin Pack - SA511CN2-3ST
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.

November 28, 2022Best Smoke Detectors on the Market
The First Alert Wireless Interconnect Battery Operated Smoke Alarm With Voice Location is one of the best smoke detectors I've ever owned. The fact that they are interconnected via Bluetooth, and have voice location so you know which detector sensed smoke, makes them one of the safest and best smoke detector you can buy. The process of linking all of my detectors together was simple. This detector is a must if you want to protect your family and make your home safe from the horror of a home fire.

We've been installing these in houses we rent, and this past December one of our tenants awoke in the middle of the night to these smoke alarms all going off at once. Long story short, our tenant made it out of the house in time. These worked as described when it mattered.
