The first choice of many installers. Although now owned by pyronix and has been for a while so not sure why they still calling it castle lol, and now accommodates upto 76 inputs
Wouldnt bother with arc unless your insurance requires it. Just get a quote to upgrade it to a v10 with app and maint contract. we are about 14 a month for contract with app, replacement parts and any self inflicted system issues charged extra
I would say the 17 is good value with any replacement included, but how often do u actually need to replace parts... Get a price from a few local companies may find them a bit cheaper im assuming its with chubb going off the picture you posted?
