R314.2
Whose great idea was this? They shall be permitted. In the significant IRC code change book (and I sit on a technical advisory group evaluating the 2009 IRC who is recommending deleting this section).. there is no requirement for a redundant system.
Even a home builder who puts in the ADT system thinks this is stupid.. it requires a dedicated phone line (how many people in this day and age even HAVE a home phone..)? An automatic dialer.. (well, ok)... and puts the burden squarely on the homeowner (circumstances change from time to time... their phone line is disconnected)... and without a redundant system.. no longer any smoke alarms..
The level of protection may not be there... NFPA 72 (which like all NFPA standards) is confusing.
Something special about these systems that 9 of us are missing
