Smoke & Fire Alarm September 21, 2016
Reviewer: Anonymous Person from Chesterfield, VA United States  
We hired an electrical contractor to install the new ceiling-mounted smoke & fire (photoelectric & ionization) alarm.  It complements a new wall-mounted carbon monoxide alarm.  Both alarms are top-of-the-line models highly recommended in Internet reviews.

First Alert 3120B Hardwired Photoelectric and Ioni September 14, 2016
Reviewer: Greg from Redondo Beach, CA United States  
I replaced my existing 5 to 10 year old smoke detectors with the 3120B units.  The old ones would occasionally beep in the middle of the night even though the batteries were fresh.  So one by one they became disconnected.  The 3120B dual unit is a much better and safer option for my family, coupled with ionization/CO detectors in the hallways.  I liked the design of the mounting bracket, and they have all been trouble free so far.  I don't know why everyone doesn't put this in immediately, your families safety is worth it.
