Hello fellow code enforcers. How have any or all of you been dealing with the use of IP as a communications circuit for fire alarm? Specifically, the back up power requirements. How are you seeing the modems/ routers powered to meet the 24 hour back up power requirement? A UPS wont do it. The largest one I've seen runs about 8 hours. anyone out there have a code compliant solution?
