About First Alert SMICO100-AC Interconnect Hardwire Combination Smoke & Carbon Monoxide Alarm
65% appreciated the loud alert
I compared the alarm loudness of two different models and found that the BRK SC7010B has a louder and more noticeable alarm.
69% praised the long-lasting durability
The alarm has been installed for 7.5 years and is within its expected lifespan for a combination smoke carbon monoxide alarm.
76% found it easy to install
Installation was super easy for me, a non-handy person.
Installing these smoke detectors was relatively easy. Each detector came with its own hardwire to use. I had to unscrew the old plate from the old detector and install the new plate, which took the longest as unscrewing took a little bit because of the long screws. These detectors do not come with screws for the plate, so if you need screws, go to Home Depot first or somewhere similar. They come with instructions so they should be pretty easy to follow if needed.
It took about a minute to install.
