FAQ:
Q: How does the sa511cn2-3st work?
A: The SA511CN2-3ST units use what is called a mesh network, meaning that the signal is not linear from one unit to the next. The benefit of this technology, according to First Alert, is that “the mesh network of alarms re-routes and resends the signal via the other alarms, providing a greater chance all alarms will receive the signal.”
Q: How does the First Alert sa511cn2-3st Wireless smoke detector work?
A: The First Alert SA511CN2-3ST Interconnected Wireless Smoke Alarm with Voice & Location is battery operated and features an 85-decibel alarm with voice alerts that tell you where the danger is located. A photoelectric sensor detects smoke while minimizing false alarms from cooking or shower steam.
Q: How does the First Alert pr710 compare to the sa511cn2-3st?
A: For roughly $15 more, First Alert sells a similar model with a pathway light that turns on when the alarm activates. The First Alert PR710 (right) is noticeably thinner than the First Alert SA511CN2-3ST (left). Photo: Michael Murtaugh
Q: Is the First Alert sa303cn3 battery powered smoke alarm any good?
A: The First Alert SA303CN3 is slightly better at detecting fast, flaming fires than the rest of our picks, but it’s generally slower to go off, and it’s best as a supplemental part of a system. For the most complete and effective smoke alarm system, we also recommend adding one First Alert SA303CN3 Battery Powered Smoke Alarm per floor.
