Rated 4.3 out of 5 by 6 reviewers.
Rated 5 out of 5 by I tested this smoke alarm and it did not disappoint. After watching a Dateline show about smoke detectors and the failure rate and times of ionization detectors I was shocked. Like most homes in America I had ionization detectors. I did some online homework and purchased these detectors. In a contolled warehouse I conducted my own test with my old dector and this dual heat and photoelctric. I first burned some toast and my old one as usual goes off, the new one did not. No more false alarms! Then I slow smoldered a couch cushion with a soldering iron. The new one went off after just 6 minutes versus 23 minutes, A full 17 minute difference. I repeated the test with a piece of wood and the results were nearly the same. Folks, for your own safety and your children please check your smoke alarms and replace them as soon as you are able. Your life and the lives of your family could depend on it. March 25, 2013
Rated 5 out of 5 by The BEST Dual Sensor Smoke Alarm out there! This alarm is the best smoke alarm you can buy. It combines the 2 real sensors, photoelectric for smoldering fires, and HEAT, not ionization for Fast Flaming Fires. From recent news reports, Ionization alarms have over 8 times the false alarm rate of photoelectric alarms, and when it comes to slow, smoldering fires, ionization respond 30 MINUTES later, or sometimes, not at all. This alarm is install in several areas in my home, and I can burn all the toast I want, it will not go off, the way it should be. The Gentex brand is widely used in commercial buildings, far higher quality then most competitors. You only have one chance to get this right, make the right choice the first time. March 13, 2013
Rated 5 out of 5 by Gentex is the best for the $ I bought a few of these dual photo/heat detectors for my home a year ago, and have not been disappointed. There have been no false alarms with them, and I've learned since I bought them that the Gentex brand makes the highest quality devices on the market, primarily in commercial occupancies. I would not hesitate to spend the extra money for these parts in order to keep my family safe. April 8, 2013
Rated 5 out of 5 by Well designed photoelectric and thermal smoke alarm. I was looking for a good photoelectic after discovering that ionization detectors fail to alarm on a large percentage of fires. This unit is well designed, easy to install and nicely priced. I especially like that the test feature is a physical test of the performance and not just a battery test. I put them in our home, a guest house, a rental, a camp and gave one to each of our children. March 12, 2014
Rated 5 out of 5 by Top of the line features at a great price. Photoelectronic sensor with thermal integrated alarm that sounds early enough to react to an emergency. August 23, 2013
