Customer Reviews

Great price and product!

I just received seven of these for my home. From the research I did this is the best battery operated alarm you can get. It’s a smoke alarm, a carbon monoxide alarm, a wireless alarm, and has voice activation. It can also be wirelessly interconnected. Plus, Westside Wholesale has the best price you'll find.

Questions & Answers

I purchased 12. Based on the product image and Specifications page I expected to receive ONELINK devices. The image clearly shows the ONELINK logo and the Specifications page says "Can be used with BRK", Instead, I received BRK "First Alert" alarms. As I understand it, these are manufactured by the same company, but the "ONELINK" has additional capabilities that allow the user to interact with it remotely. Nowhere on your site do I see any reference to BRK or that the product being sold is not the ONELINK model. If this correct, your description is misleading and should be updated. I was very disappointed and thought I that I had possibly received counterfeit merchandise when I noticed that the alarms do not have the ONELINK logo as pictured and described.

The ONELINK models are clearly listed as models SA511B, SA520B, AC10-500 and DC10-500. The model ordered was SCO500B which does not have or include ONELINK options. For Combo units you will need either the AC10-500 or DC10-500 model depending on your wiring constraints.
