Questions & Answers

How do I change the battery in the smoke detector? It's the kind you have to twist on and off to keep it in place.

Customer Reviews

Hardwired Interconnected Photoelectric Smoke Alarm with Battery Backup and Temporal 3 Sounder is rated 4.0 out of 5 by 3.
Rated 4 out of 5 by from Good smoke alarms I bought 5 of these to replace all my old Kidde detectors. First off, If you buy one of these, you will have to replace ALL your old detectors, or they will all go off randomly, as they are not compatible with other brands besides Gentex, i confirmed this with tech support. I like the fact that they are photoelectric, and they are LOUD. Also, the build quality of them is amazing, and MADE IN THE USA! the manufacturing date was the same date of my purchase, Meaning it shipped directly from the factory. this is great. Some detectors sit on the shelves for 2 years or more, and then their 10 year life is shortened. I recommend it if you are planning to replace all your detectors, (Which you should anyways)

Rated 5 out of 5 by from Solution to major problem This GN-303 has been (6 months no false alarms) the solution to my many unexplained false alarms with one of the two major brands. From what I read the other big brand was no better. Perhaps power surges were the culprit as I’d seen mentioned since I’d eliminated other possible problems, but code said it had to be optical, hardwired, battery backup which didn’t leave much option for model. This is a quality item assembled in US and targeted for hotels, nursing homes (and residential) etc. where non-sense false alarms are not tolerated. You will need to switch all your alarms since they’re interconnected, but you would want to anyway. I had to split a combo to individual CO and smoke since Gentex does not make one with a simulated voice (MA code for combo).

Rated 3 out of 5 by from Not compatible with other brands Alarm "ON" - 9V, alarm "OFF" - 0(zero)V. What can be simpler than that? It's binary, right? Nope, GN-303 puts 4.8V on the "interconnected" line when it's idle which is recognized by other brands as "Alarm ON" so they all go off as soon as get "interconnected" with a Gentex. GN-303 might work just fine with each other and other Gentex products but if you're going to install mixed kinds of detectors (CO, ionization, thermal, etc.) or plan to add more options to your home later then be aware this Gentex "custom" protocol is not very standard. BTW, the "other" brands show 0(zero) on the line as much as my multimeter is able to detect. I'm glad The Home Depot has an awesome return policy.
