OneLink Works Well April 22, 2017
Reviewer: Ben from Acton, MA United States  
I wirelessly connected three SCO501CN, a CO511B, and SA521CN. The SA521CN was hard-wired to a 3120B in my furnace room. Hitting 'test' in the furnace room was heard throughout my house!

The OneLink worked great and the SA521CN worked as a bridge between hard-wired and wireless connections.

Great Experience March 25, 2017
Reviewer: Daniel MacDonald from New Boston, NH United States  
For all of the purchases I would not think of going to any other outlet for these items. SmokeAlert's employees provide the best advice and expert designs to ensure I get what I need without overspending. Can't find this kind of customer service anywhere,..
