The Code Council has revisited how best to provide an online, professional Discussion Forum and area within the website that has a sense of community – where Members and nonmembers can provide input and exchange ideas with their peers in the industry. The new Codes & Standards Discussion Forum does just that, as it allows Registered Website Users and ICC Members to discuss the I-Codes in an online community.
Note to Nonmembers: If you join the ICC you can have access to important building safety information!
As an ICC Member, you have access to the Members Area of the Codes & Standards Discussion Forum. Follow the link to discuss the Membership Councils and other benefits of being an ICC Member.

2009 IRC, R314 SMOKE ALARMS.
Just had a call from an Electrical Contractor; stating that a subdivision he is contracting the electrical in, does not require hardwiring of smoke alarms; because they are all monitored (single family homes) by a monitoring company.
Any one know of an exception where smoke alarm hard wiring is not required in new single family homes?

R313.1 Smoke detection and notification. All smoke alarms
shall be listed in accordance with UL 217 and installed in
accordance with the provisions of this code and the household
fire warning equipment provisions of NFPA 72.
Household fire alarm systems installed in accordance with
NFPA 72 that include smoke alarms, or a combination of
smoke detector and audible notification device installed as
required by this section for smoke alarms, shall be permitted.
The household fire alarm system shall provide the same level of
smoke detection and alarm as required by this section for
smoke alarms in the event the fire alarm panel is removed or the
system is not connected to a central station.

Thanks for the answer;
"The household fire alarm system shall provide the same level of smoke detection and alarm as required by this section for smoke alarms in the event the fire alarm panel is removed or the system is not connected to a central station."
I don't have NFPA 72; and losing my ability to understand some of these code requirements; the way they are written. Does that mean that they are required to be hardwired? It seems to me that it would be difficult to "provide the same level of smoke detection and alarm without hardwiring; if the fire alarm panel is removed or the system is not connected to a central station.
To me this requires for hardwiring of all new systems; so the code requirement is met without additional wiring and/or cost to the homeowner.

I agree with your assessment. The smoke alarms cannot be dependent on a fire alarm panel or other monitoring system, alone. There is nothing prohibiting the smoke alarms from being connected to & monitored by a central system, as long as they will continue to operate via the normal premises wiring system.

I though I was reading it right; but, it's always helpful to have someone who knows more than me either affirm my understanding, or explain where I'm wrong.

There is some confusion here since two different years of the IRC are being quoted. 314 is the 2009 and would allow wireless smoke detector system as per 2007 nfpa 72 article 11.7.7. The 2003 and 2006 does not allow per 313.
Here is a link for free vews of nfpa codes but you can't copy.
