    Not only do they alert all six detectors in my house to sound the alarm, they talk... telling me the location of the unit that triggered the alarm. Amazing technology!! Nothing but great for the safety of my family.

    Customer has been confirmed to have purchased the item from Walmart.

    Everyone in our house sleeps with noise machines or box fans. I am always worried I won't hear a smoke alarm going off at the opposite end of our house. Therefore, we wanted smoke alarms that would all go off at the same time. However, hard wiring new alarms was not a project we wanted to tackle right now. When my husband found these wireless alarms, we knew it was the way to go. We bought 2 sets (4 alarms total). All 4 alarms sync with each other. Each set comes with a set of paper instructions and an instructional dvd. The dvd contains fire safety tips as well as how to program the alarms. I skipped ahead to the actual instruction and it took all of 5 minutes to set up and sync. Then you just install them like regular battery operated smoke alarms. It is suggested you test them weekly. I assume this is to make sure they still sync with each other properly. We have one alarm at one end of the house near the garage and utility room. We put the remaining 3 alarms at the other end of the house-one in each bedroom. The distance between them doesn't cause a problem. The voice option is a little scary sounding. However, the 'voice' tells you exactly which alarm is detecting smoke. I would highly recommend these alarms. They seem pricey, but it was worth it to us to skip the hard wiring. Also, you can always add and sync more alarms later.

    Be sure to watch the installation video as you need to program this while the devices are in close proximity - not once they are spread throughout the house. The voice alarm is loud and clear and will alert everyone in the residence. It was purchased for an apartment and worked great in test mode. Hopefully we'll never need it to work for real!

    These alarms are easy to set-up and appear to function well, already sounding an alarm due to a kitchen project gone wrong. All First Alert OneLink alarms interconnect; this is obviously an excellent feature. Note that First Alert also manufactures OneLink CO-smoke dual detectors.

    I am very pleased with the product even has a DVD to give information and helpful to operate. I installed one alarm in my home and the other in my attached garage but the alarm in the garage does not signal to the alarm in the home. When placed in home and basement they perform just as expected.

    Linking the alarms really makes the family feel secure, there is no fear of not hearing the alarm because its in the basement and we are asleep. It rings on all floors and announces where the fire has started.

    The only thing that could make these smoke alarms better would be if they were both ionization and photo electric in one unit plus heat sensing. You really shouldn't be without these detectors the photo electric type that is.

    This product is going into my mothers home. The wireless feature is exactly what I was l looking for. The voice feature with hazard and location make this product the best on the market. The DVD instructions will make the installation very easy. Thanks to First Alert and Walmart.com. I cannot say enough good about this whole transaction.

    • A. Personally, we have 4. I have read the instructions, and there does not appear to be a clear answer on how many. I'm assuming there is no limit. The example diagram shows 6 on multiple floors. The actual PLACEMENT of the units is what matters. There can be obstacles in the home (like suspended ceiling, ductwork, metal studs, etc) that could affect their sync. It says they can sync up to 50 feet away.

    • A. From the FAQ on their website - "First Alert® ONELINK® is a complete integrated wireless smoke alarm and carbon monoxide alarm system. As with hardwired units, NFPA states that up to 18 total units can be interconnected (RF or hardwired) with a maximum of 12 of those being smoke alarms and the balance carbon monoxide alarms. Take maximum advantage of the flexibility and protection that a First Alert® ONELINK® integrated wireless alarm system can provide."
