Agreed, I still have to much trouble with the &$*# and the internet.
Thanks for the advice, Excel is on their way again, and we have vented the house, I am tired of waking up fire fighters. We just have some tired CO alarms. BTW I can recommend First Alert fully now, three times they have saved my wife and I in as many days.

Also with the FD and utilities fixing it. both their machines registered high on two occasions, and the FD vented the house and left both times and Excel puts fix it tags on em and leaves. The land lord just called a terrible crew who left me hanging in the wind and excel cleared it to work which was followed by another set of alarms.
