wireless battery smoke detectors?

[Coppersmith]

Are there any code compliant smoke detectors that are battery only (no hardwire) with a wireless link? This is for a house that is being remodeled.

See here for a Kidde product.

So not required by code (NEC, life safety, building) to be hardwired to AC power?

I'm looking at NFPA 72-2013 section 29.6.1 and it seems to indicate a smoke alarm can be operated on just a 10 year sealed battery but I'm not sure I'm interpreting this correctly.

It depends on AHJ I think for interpretation, here battery wireless interconnect is acceptable.

Yes, battery-only would be fine. Building codes may still require hard-wired smoke alarms for new construction, renovation, or additions. The big market for battery-only is current housing stock built before hard-wired alarms were required.
