Rated 5 out of 5 by 4 reviewers.
Rated 5 out of 5 by Very pleased with this purchase We purchased 5 of these units to replace the 17-year old (different brand) smoke alarms in our home. The Gentex wiring instructions are clear and simple to follow. The units have a green light (see pic) that lets you know they are working. We have had them in operation for about a month now without the first nuisance alarm. The old ion-type models would go off just about everytime we cooked. Our local HD does not carry these in-store so we ordered them online. Shipping was not only free but fast too. We are very pleased with our purchase. April 9, 2013
Rated 5 out of 5 by So far, no nuisance false alarms!! Excellent due to no false alarms I've gone through a lot of photoelectric hard-wired alarms with tenants who cook -- they have been setting off the alarms then they disconnect the alarms! So I needed to find one that does not go off just because they are cooking. So far, cross my fingers, there have not been nuisance alarms with this brand -- I've tried Kiddie and First Alert (remember I have to have hard-wired types due to the City of Los Angeles codes) and they all went off. I will never get a combined type of carbon and photoelectric since those types tend to go off sooner; plus the manufacturer's recommendation that the carbon monoxide alarms and the photoelectric have different distances from the ceiling.

Rated 5 out of 5 by Easy to Install- Latest Technology These three alarms were easy to install- (replaced 28 year old hardwired alarms). They were touted to minimize nuisance alarms and they did- I scorched toast a few days ago and the alarms didn't go off. It wasn't a lot of smoke and I opened a window and turned on the exhaust fan right away, but no alarm. BTW, they all work when I check the test button, so I don't believe they are defective.

Rated 5 out of 5 by Works as it should We chose this product because it does not have batteries (they always die in the middle of the night...). Installation was easy (I just had to swap the wires of the old unit with the wires of this one), the detectors have been installed for 3 weeks, nothing wrong so far. August 8, 2012
