Average Reviews:
(More customer reviews)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.

Here is an update. I gave up with trying to make these pieces of crap work. I understand BRK is coming out with a new model ac/dc photo/ion with latching, etc. Alas, it won't be out til December, 2010, a delay from the Aug. date currently seen on the BRK website in the catalog pdf. I took these 6 down and threw them away and replaced them with 6 7010 photos and 6 9020 ions. Sure there was a little work extending them but the silence is golden. It gives the place a high-tech look too - yeah right.
