Convenient 6 pack

Everything we need to protect our home was in one box. We got rid of a hodge-podge of smoke alarms from various companies and standardized on the best, according to Consumer Reports.

Easy to install, works great

Smoke detector SA501CN-3ST. Installed 3 of these smoke detectors on 3 different levels of my home. There were metal ducts in the vicinity. All 3 detectors communicate fine, and all 3 alarm when any are tested. I wanted to be able to hear alarms from anywhere in my home, and these detectors make that possible.

Easy Wireless Interconnected Alarms

The alarms were easy to install and link wirelessly with my bridge units. Casing feels slightly cheap and the mounting screws were hidden in the battery compartment but otherwise a good product.

Problem Free!

I ordered 2 - 2 pack wireless smoke alarms. I was a little concerned about getting them all to talk to each other but the instructions were easy to understand and the unites responded just as the instructions said they would. After testing the units and terrifying the dog was pleased that they work exactly as promised. They arrived quickly and in excellent shape!

Like the convenience of Onelink

I easily found the information I needed to make my purchase decision to expand the number of detectors in my house. Ordering was easy and I received the detectors I ordered in just a couple of days. My only complaint is that the detectors are a bit pricey. They were very easy to install and set up.

Wireless Smoke Alarms

The product is outstanding. Your installation instructions on the DVD made it a pleasure to install the units. Outstanding visual aid for easy installation.

What is a mesh network and how do the First Alert Wireless Interconnect smoke detectors intercommunicate?
First Alert Wireless Interconnect smoke alarms operate on a "mesh network" to integrate smoke alarms for better safety and response in an emergency. All of the First Alert Wireless Interconnect alarms send, receive and resend the initiating alarm's signal. Why is this important? Let's say the signal is blocked from reaching the master bedroom alarm either by distance or some obstruction in the home. With First Alert Wireless Interconnect, the mesh network of alarms re-routes and re-sends the signal via the other alarms, providing a greater chance all alarms will receive the signal. The "mesh network" is a more reliable means of wireless communication.
What is the proper placement of smoke alarms?
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.
My smoke alarm keeps chirping and beeping. Why does my smoke alarm chirp intermittently?
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.

Why doesn't my smoke alarm sound when I push the test button?
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.
Why does my smoke alarm go off when I install a battery or turn on the AC power?
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.
My smoke alarm keeps chirping, even with a new battery. What is causing this?
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.
I lost my First Alert smoke alarm owner's manual. How can I get a new one?
First Alert smoke alarm owner's manuals are available online for download at no cost. Find your alarm in our Smoke Alarms section.
Why does the National Fire Protection Association (NFPA) recommend that home smoke alarms be replaced after 10 years?
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.

I'm ready to change my alarm battery - what replacement batteries can I use?
Check your User's Manual or the nameplate on the back of the alarm. Different smoke detectors & CO alarms use different kinds of batteries - 9V, AA, AAA - it all depends on the particular model you have. Use quality batteries like lithium batteries - having plenty of power is worth any extra cost. Never use rechargeable batteries because they may not always provide a consistent charge.
