CUSTOMER REVIEWS

Rated 4.6 out of 5 by 21 reviewers.
Rated 5.0 out of 5.0 by works great I bought this to replace an existing one that wasn,t working properly. December 8, 2015
Rated 5.0 out of 5.0 by Kiddle Smoke Detector I looked at several smoke detectors at Home Depot before choosing this particular one. It has the best price performance ratio. The instruction booklet is excellent and easy to understand. The detector itself seems to be good quality. As an added bonus it comes with a battery backup already installed. December 17, 2013
Rated 4.0 out of 5.0 by Completely satisfied replaced original without having to change the base, which was important to me March 31, 2015
Rated 5.0 out of 5.0 by Easy install Worked great for my replacement situation. Base plate has multiple holes to punch to match your existing situation. The red line is capped in case you are not interconnecting the home alarm system together. Had an existing connector so cut the wires off at old alarm and used wire connector caps to connect the black and white wires together. Easy to see green light. Comes with a 9 volt battery. October 28, 2014
Rated 4.0 out of 5.0 by old inventory i bought 7 online for one location and 8 from the local store for another location. the dates that these units were manufactured (for the online purchase) was 2013...while the ones in the store were made in 2011! i am trying to be proactive and keeping the units in my home "fresh"....but Home Depot is not doing me any favors with stale merchandise. the actual units were easy to install. about 5 minutes per unit and they are white, unlike the Firex units they replace which were off white. blend into the ceiling nicely. June 3, 2014
Rated 4.0 out of 5.0 by Very good product! I was replacing a fire detector of the same model so no new wiring had to be done. It was a great replacement for the old model and they did some nice updates on the new model. The one very nice feature that they didn't change is the size of the detector so it fit exactly like the old one! Well done! November 4, 2014
Rated 5.0 out of 5.0 by Great replacement! I needed to replace a previously installed hard-wired smoke detector which appeared to have gone bad (replacing the 9-volt backup didn't stop the constant chirping!). I did some research and found that this model was a perfect fit for the base of the previous one (a 1275 ionization smoke detector). It has been almost two weeks since I installed it and I don't hear those 30-second chirps anymore! The price was reasonable and ordering online and picking up in-store was a breeze. I will be using this smoke detector for future replacements! January 3, 2012
Rated 5.0 out of 5.0 by very good they found replacement fastners for my blind. it took them a while but they persisted using your inventory statement May 27, 2014
