If you have a hardwire installation already then this is a great option to put a dual sensor smoke and carbon monoxide alarm together in one with a 10 year backup battery. USI does make a 10 year battery-only product but it seems it is completely out of stock across the nation.

I have them in 4 houses. Best if all the same brand. turn off power before taking any up or down, if they are interconnected, for a proper reset. the twist lock mechanism isn't very tolerant of popcorn ceiling or an electrical box less than flush to the wall.

These are great detectors. We used to have 4 smoke detectors and a single stand alone carbon monoxide detector on only 1 floor. Now with these 3-in-1 detectors we have smoke, fire and carbon monoxide detection on all floors of our home! They also look good. They are also AC hardwired with battery backup and all our detectors are interconnected so if 1 goes off they all go off.

Combines smoke, fire and CO detector in one. Very easy to install as a direct replacement for my old USI smoke detectors. No need to change batteries every year.

I replaced my old alarm with this newer model because the old one would not stop giving false alarms and would beep through the night. This is a newer model since I guess the old one was discontinued. The false alarms stopped once installed and according to the manual this doesn't need a battery change for ten years (where you just replace the alarm itself rather than the battery), whereas I must have went through a box of 9volts trying to troubleshoot the old one without any success.

The product was easily installed and I was able to use the previous connector without having to swap out for the new connector hardware. I only had to swap out the mounting bracket. Just ensure to follow directions and it's good to go.

Excellent product and easy to install. The manufacturer provided fast warranty exchange on one of three items that had a backup battery that failed to activate.
