First Alert 3120B Hardwired Photoelectric and Ioni November 19, 2014
Reviewer: Parkview HOA from Park City, UT United States  
We are a Condo HOA.
Installed just under 200 combo Photoelectric/Ionisation hard wired smoke detectors. They replaced our First Alert Hard Wired Ionisation smoke detectors which had run their lifecycle.
Photoelectic/Ionisation combo works well.
The photoelectric has gone off in several units as a result of flash fire in the kitchen.
The only complaint I got was that the noise from the connected detectors drove everyone outside!!
I consider that a win.
The old ionisation only detectors would not have gone off until there was smoke.

SmokeAlert.com November 17, 2014
Reviewer: Anonymous Person from Bristol, CT United States  
Products purchased performed exactly as described on the SmokeAlert.com website.  The website is intuitive and very easy to navigate and the "What Are The Best" articles are both informative and helpful.  I phoned the company to ask a question or two and my call was returned immediately by Chris, who was extremely helpful.  I highly recommend this company and their products.
