Reviewer: robert salverda
I own a small mobile home park. I decided to buy 10 year smoke detectors due to new insurance rules, specifying I had to check the batteries once a week, which is ridiculous. I received the alarms but all it says on the packaging is that the alarm is guaranteed for 10 years. It also states the lithium battery doesnt need to be changed as much as a regular battery. So is the battery guaranteed to work for 10 years or not? What am I supposed to show the insurance company now? Definately false advertising on this product. Other products from different companies specifically say the battery is guarenteed to work for ten years, but yours doesnt unless you go online to see your product desciption. Call me if you have an explanation for me... 352 299 6926

Customer Service Response:
Hi Robert, The manufacturer of the battery lists the battery as a long-life 10 year battery. What First Alert has found is that due to the battery being in a safety device with a high low-battery threshold, there is a strong likelihood the battery will only last 4-5 years. If the battery does die sooner than the 10 years, you can call First Alert directly and they will send you another battery. Despite this being a long life battery, it is still recommended by First Alert, the Red Cross, and many other safety organizations that you check your alarms once a week just in case a problem does arise. Thank you for choosing First Alert Store and have a safe and Happy New Year!

Reviewer: Michael Lee
I had seen plenty of reviews on the web complaining about the battery dying after a few months. I figured that most satisfied people dont write in. So I bought the alarm anyway, thinking that I would take a chance since I would save the cost of many batteries over the 10-year life. What I did not anticipate is how poorly the product is design. Since the true test of the alarm is when a fire occurs, I hope that function would never be tested. But the only two thing that could go wrong were in fact so. First, the instructions stated that the battery should be put in with the + and - terminals coinciding with the markings on the housing. After a long examination, I found no markings anywhere on the alarm. If it was there, it certainly could not be seen. The writing was barely visible because they were white on white with absolutely no contrast. I have very good eyes, and I could make out the writing. But the terminal markings were nowhere to be found. Im pretty handy, so it was obvious which way the battery should go. But I never found the confirmation I sought. After that, I twisted the alarm into the the base. Well, actually twisted it, and it went up against a stop. But it was completely loose. I live in California, and any trembler would have knocked it onto the floor. The only way around the problem is to put in the locking mechanism, which then secured the alarm against the base. But would I remember that I had done that 10 year from now when I plan to replace the alarm? Or if I sell the house, would I remember to tell the new owner about what I had to do to secure the alarm? He would blame me when he has to rip up the ceiling to get it off. My no-name Fire Sentry alarms that my contract had put in snap in perfectly. So do the other First Alert alarms the I had put in recently. Whoever designed this decided to redo the mechanism apparently never looked at how previous one were done. He or she decide to reinvent the twist and put the product into production without ever testing to see how it works in practice. For a company like First Alert, the oversight in these two aspects is absolutely inexcusable.

Excellent value and reliability. Pays for itself in savings on batteries over the life of the smoke alarm.

Q: How often do you need to change the batteries?

A: Actual battery service life depends on the particular design of your smoke or carbon monoxide alarm and the environment in which it is installed. All kinds of alarm batteries specified in the user's manual are acceptable replacement batteries. Regardless of the manufacturer's suggested battery life, you MUST replace the batteries immediately once the unit starts "chirping" (the "low battery warning"). It is recommended that you change the batteries in your alarms when you change your clocks for daylight saving time. Also consider replacing your current alarms with 10-Year Life alarms that never require a costly battery replacement for the ten year life of the alarm. This 10-Year series is available in smoke, carbon monoxide and combination alarms.

Q: What is the proper placement of smoke alarms?

A: It is important that you have the proper placement for your smoke alarms. Install your alarms at least 20 feet from appliances like furnaces and ovens, which produce combustion particles. Alarms should be at least 10 feet from high humidity areas like showers and laundry rooms, and at least 3 feet from heat/AC vents. Be sure to install a smoke alarm in each bedroom, one at the top of each stairwell, and one on every level.

Q: My smoke alarm keeps chirping and beeping. Why does my smoke alarm chirp intermittently?

A: It is likely that the reason your smoke alarm keeps chirping and beeping is that the battery is low. Whenever your smoke alarm keeps chirping, replace the battery immediately.

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.

Q: Why doesn't my smoke alarm sound when I push the test button?

A: It is important that you frequently test your smoke alarms. When you are testing your smoke alarm, there are a number of reasons why the alarm might not sound:

  • 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.

Q: Why does my smoke alarm go off when I install a battery or turn on the AC power?

A: It is normal for smoke alarms to go off and sound briefly (up to 5-10 seconds) when you install a new battery or when they are powered up. If the alarm continues to go off and no smoke is present, the cause may be one of the following:

  • 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.

Q: My smoke alarm keeps chirping, even with a new battery. What is causing this?

A: There are a number of possible causes for your smoke alarm to keep chirping even with a new battery.

  • 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.

Q: I lost my First Alert smoke alarm owner's manual. How can I get a new one?

A: First Alert smoke alarm owner's manuals are available online for download at no cost. Find your alarm in our Smoke Alarms section.

Q: Why does the National Fire Protection Association (NFPA) recommend that home smoke alarms be replaced after 10 years?

A: Smoke alarms have a limited life. Although each smoke alarm and all of its parts have passed many stringent tests and are designed to be as reliable as possible, any of these parts could fail over time. Therefore, you must test the devices weekly. The unit should be replaced immediately if it is not operating properly. The performance of smoke alarms older than 10 years is simply not reliable. To ensure your family's safety, all carbon monoxide and smoke/CO combination alarms need to be replaced every 5-7 years. All smoke alarms need to be replaced every 10 years.

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.
