RE46C180E16F - CMOS Programmable Ionization Smoke Detector COM-14994 ROHS
I have not been able to find any code or hookup guide for this device. We are using Sparkfun redboards for our projects. Any helpful ideas?
That chip is designed to be used in a standalone detector, so they don’t have a convenient way of doing this. Two options come to mind - use the interconnect pin and live with the 3.7 second delay, or use the RLED output. If you use RLED, you will need to ignore whatever the chip does for the low battery detection (it looks like it periodically flashes the red LED as a load on the battery, so you need an LED. Also, watch the voltages; they are not regular logic levels.

You’re probably better off hacking a working smoke detector than trying to use this chip. This part is just one component in a smoke detector and you’d essentially be building a smoke detector from scratch using this chip. (The chip itself doesn’t detect smoke)
Also, it’s OK to experiment with Arduino and smoke detectors, but DO NOT use these for a life safety application. If your code should happen to crash and the detector not work, it could cost you life, or at the very least burn down your house.
