Thank you Ryan I should have pointed out that the detectors that I installed were retro and not in a new home. These were mounted beside of the beds in the bedroom and were for people that were using oxygen. Two of these detectors activated both audio and a strobe light which came with them.

My brain shorted and the thought of the combo type didn’t enter my mind. The only ones that I though of was those that I had installed last fall. [Linked Image]
Trumpy has me holding my horse over in the General Discussion Area and I am wore out from holding on to his tail so I will blame it on him. [Linked Image]
