In a residence we are wiring the smoke detectors with 14/2 NM. This is an Arc Fault protected circuit. Is it permissible to use a #16 wire single conductor separate from the NM to interconnect the devices? Also what is the voltage of the interconnect circuit for standard smoke detectors?

Re: Smoke Detectors
This is not an NEC issue exactly. Check the manufacturers instructions on interconnecting methods. SOme permit as small as #18 AWG for interconnecting.
Why bother though? Why not interconnect with 3-wire NM thus supplying the smoke alarm and the interconnect at the same time?

In one home how much is actually being saved by wiring smokes in 2 wire,and adding a seperate signal wire
I have been doing residential for all to many years and have never come across this.
