First Alert/Brk Brands Smoke Alarm 120V w/Battery SA773CN Reviews
| 3 of 3 people found the following review helpful:  Dual mode smoke alarm, By Amazon Verified Purchase This review is from: First Alert/Brk Brands Smoke Alarm 120V w/Battery SA773CN (Misc.) The smoke alarm is fine - no problems with it. The only issue I had in ordering this was I ordered a SA773CN and I received a SA770LBX. The difference is in the electrical connector. Since I was replacing existing smoke detectors, this difference caused me to have to change the connector in the wall before I could install this detector - an extra step that I tried to avoid by ordering the SA773CN part number. 5 of 6 people found the following review helpful:  False alarms in an old package, By Karl (NY, USA) - See all my reviews This review is from: First Alert/Brk Brands Smoke Alarm 120V w/Battery SA773CN (Misc.) Five 15-second duration false alarms in two months, with no obvious triggers. Not enough time to find the offending unit in an interconnected system with six detectors since this detector does not indicate which detector set off the alarm. BRK suggests disconnecting the wiring harness and run on battery power alone to isolate the bad actor. That's going to take a while and what does it really prove if 120 v. AC is disconnected? Other negative issues are that the battery is behind a screwed-in door on the back of the detector, so you have to remove it to get at it - an old design. Also, it's not very current when it comes to air sealing. Other detectors make a good seal on the ceiling; this detector has a piece of paper you put in between the detector and its base - hardly air proof. In addition, as I said earlier, it lacks the feature of some BRK's other products of having a memory alarm, or "latching" feature which shows which detector initiated the alarm...

This model wasn't actually designed by First Alert/BRK, but is a rebranded and slightly modified (different connector) version of an old American Sensors model (770LBX), and hasn't been updated in years. For example, this model only has a red LED, while most current hardwire smoke alarms have both a red LED and a green LED (green to indicate AC power and red to indicate the alarm is working as well as to indicate which alarm went off). If you have an old First Alert/BRK setup but want a dual sensor alarm, your best bet would be to buy the Kidde PI2010 plus a Kidde KA-B adapter. The PI2010 is a much newer and more modern alarm. EDIT: I just learned that there is a new BRK/First Alert hardwire dual sensor model, the 3120B. However, very few stores seem to carry it, and it costs more than the Kidde PI2010. |
