Hi,
Since hardwiring of smoke alarms is a must, I wonder if bus-powered alarms are allowed (i.e. 24v on the KNX bus), or do they have to be wired to 220v? The reason I want them networked is so I can easily look at a control panel and tell where it is, as well as vpn into the house from somewhere else and kill any false alarms, or take action if need be.
Is it allowed to do it that way?
