What I appreciate and admire about First Alert is I was able to buy the same model I had and it fit perfectly on the base. I am so thankful to be able to swap out my old smoke alarm for my new smoke alarm in seconds!

Products were properly pulled from the shelf and sent. Arrived in good shape and the 2 units replacements for existing were installed the next day and found to be working. I highly recommend this retailer.

First Alert products are excellent, including this simple battery powered smoke detector. I used this one to ensure I had both PE and Ion detection in a bedroom. The First Alert Store has great prices, very quick shipping and superlative customer service.

We recently purchased a house that came with a SA303 from 2009. Happy to say that the newer model SA303CN3 fits into the existing bracket. Put in a battery, close the lid, and twist in -- as easy as pie.

I have always bought First Alert Smoke Alarms and I like them. Thank God I have never actually had a fire to really test them.

December 12, 2019THAT Was Easy!
I was especially impressed with the assistance I received over the telephone. I had old alarms. Maria checked the serial number, told me that, yes, the alarms had outlasted their usefulness and then checked to recommend replacement that would allow me to insert the new alarms in the old frames. And, by the way, they were on sale. I ordered them online. They arrived promptly. Sure enough, they fit into the frames that were already installed in the ceilings. It couldn't have been easier.

The smoke alarms arrived quickly in the mail and were very easy to install. They also came with a battery which saved me time from having to go purchase one. Very satisfied with the product
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.
