I'm working on a DIY UPS solution for critical gear during power outages. Plan on using: http://www.mini-box.com/picoUPS-120-12V-DC-micro-UPS-battery-backup?sc=8&category=1264 or http://www.mini-box.com/OpenUPS?sc=8&category=1264 and http://www.trojanbattery.com/products/31-AGM12V.aspx I need to power the ISY, Cablemodem, and Router in order to send SMS/Email alerts during an outage so I'm trying to find out if all the devices can handle ~12v inputs. Can the ISY994i/IR handle a range of voltages safely? This was previously answered about the 99i but I thought I would revive it for the 994i. Thanks! -Jeff
