When adding a smoke detector in a finished attic addition, is it required that it be interconnected to the other smoke detectors in the house.

I believe so, and would want it done so anyway. What's the point of a detector where nobody can hear it?

I agree, I'm just a little concerned about compatability. Are most brand line voltage smoke detectors compatable with each other relative to being interconnected?

Most important is the location. A smoke detector must be placed so it can detect the fumes. In the wrong place, they won't detect anything till a blaze is well underway. We have one that goes off if we make toast with the kitchen door open- funny thing is, our Shitz-zui (supposedly a dog?) starts howling seconds BEFORE it goes off, so we got two!

Depending on where you live smoke detectors may not be suitable for attic mounting.

Many have a minimum ambient temperature that they can be exposed to.

Here that rules out smoke detectors in unheated spaces. In these spaces we use heat detectors which are also interconnected.

I am surprised no one mentioned the fact that this is purely a local building code issue.
These requirements are nowhere in the NEC.

I suggest contacting a local AHJ office for the exact answer.

From a personal opinion, I would say yes, interconnect them. Also use the same (or compatable) brand.

*Typo*

This is not an adopted requirement however.

In who's jurisdiction?
It seems it is a requirement in Bob's (iwire) area.

Like I mentioned before, different areas have different SD requirements.

Speedy, Scott and I live only about 45 minutes apart.

Scott is correct, I did not mean to imply it was required.

My point really was do not install smoke detectors in unheated spaces.

If fire detection is wanted or required in these areas use heat detectors.

Sorry guys, didn't mean to stick my nose it didn't belong.

I think we need a little spot for our locations like some other boards have.
