I am going to fabb up something as a project. I was in a KS campaign and got one delivered that works great, but since those are not generally available I figured a kit someone can build would be helpful. Particularly if you want unattended printing, http://www.amazon.com/Smoke-Sensor-Module-Detector-Output/dp/B008MSQO0W or http://www.amazon.com/Kidde-SM120X-Detector-Hardwired-I-Combo/dp/B001AYERC2 would be a starting point (leaning towards the first one). Then a remotely mounted though power connector and some printed parts to mount it all in. Stay tuned.
