I bought this detector after my 10 year old unit (same mfg and everything!) bit the dust and said there was fire every 3 hours. Not fun at 3, 6, 9 in the morning...you get the idea. So I did some quick research and found this unit to be priced well, and did the purpose of heat and smoke- just what I wanted. Because this was the same mfg, the installation was almost wire for wire- not much needed to change. The instructions were clear just in case you're not comfortable doing this. But I think I had the old one down and the new one up within 7 minutes. And works like a charm! Tested it out with a hair dryer and then with a candle that I blew out...quick response, very pleased!
In a nutshell, if you want a smoke/heat detector that is easy to install and reliable. Go with this one!

easy to understand instructions. had to drill 1 new 1/4 inch hole for the connecting wire. old mounting holes fit just fine. tested ok on first try. cost a lot less than the original sensor that was 20 years old. inflation may be rampant elsewhere, but System Sensor prices are going the other way. thank you System Sensor for a nice product at a really good price. lucianphoenix, retired electronics engineer.

This sensor was easy to install and works perfectly. Needed to replace 4 of them due to age of originals, i suppose. Could not find locally and was a little worried until these arrived. Perfect.

This is the replacement for an older model. This is also the third time the connection has changed from the original in my house (ok, it has been 15 years). you will have to take off the old base and remove a connector if you have one. then wire the new base and install and yes if you do not shut it off the alarm will go off. not really hard to do, but it will take you a good 10 minutes to do this.

I bought two of these to replace old alarms. Neither came with a base. The box clearly says "with base" and picture on the box shows a base, just like this picture used on Amazon.com. But a base wasn't included with either of the two boxes. LOL I would give no star since I couldn't install it but it's not a option. They are going back to Amazon.

Arrived fast and in excellent condition. However, I had to return it because it would not work with my security system. It look a phone call to the vendor to get the refund processed, but the company was helpful and gave me a full refund, including shipping. My only counsel is that if you are looking to buy this to replace a defective sensor which is connected to a national / "brand name" monitoring system / company, that you contact your monitoring company first a) to ensure compatibility, and b) determine if you are allowed to install the device on your own without such action affecting your contract with that company.
