easy to install especially if you already have the newer bases installed-also like the AA cells replacing the older 9 volt

Easy To Install
Installed all 4 of them and interconnected them, one in each bedroom and the basement.

I purchased this model because of the dual smoke detection features plus the carbon monoxide and I am happy so far with the product.

wired in dual smoke alarm
Son-in-law had no difficulty with installation. No false alarms which was major problem with original from another company to point it had to be disconnected.

First Alert Great products
I have just recently replaced all my smoke detectors throughout our 10 room B&B. I bought all First Alert units and particularly like the 2 AA battery design rather than the 9 volt. The batteries are much cheaper. I also later bought three wireless for each floor to improve fire alter status.

I needed a replacement for a discontinued Tek electronics model IL_930 Ionization smoke detector and this was perfect. Followed the directions and was easy to install plus it looks good. One very satisfied customer!

Easy install. Works great.
Replaced builder grade of competitive brand that was 10+ years old. Good to now have both smoke sensing technologies. Detector comes with batteries, mounting plates, paint cover and wiring pigtail. Remove old detector, wire new pigtail and base plate and plug it in.

I am replacing cheap and the installation was simple to carry over. No false alarms, which was problem with cheap.

Easy to install and looks good. Works well with first alert co/smoke detectors already in the house.

After seeing some research about smoke detectors. Our business highly recommends dual sensing units over the low price Ionization to help my family and our customers feel safer.

BRK Hardwired Smoke Alarm
Excellent replacement for my Mother's Ten-Tek Electronics Model IL-930, Ionization Smoke Detector. Apparently Ten-Tek is out-of-business. Now I have a hardwired Smoke Detector which will detect both Photoelectric and Ionization fires.

We needed to replace our 3 smoke alarms so I contacted you. They came pretty fast & out daughter's boyfriend put them up. Only problem one of the alarms needed different batteries, so I suppose the other 2 will follow. Thank you.

Good item where fire and smoldering is a risk. I placed this one in an area of my stair well. This item seems to have a longer delay when testing with the interconnect hardwired. Would have liked it to have co. as well.
