4 wire smoke detectors alway show smoke detected

 So, I am new to this.  I setup the Konnected diy kit and all is good on doors and window switch function however I am having issues with the smoke alarms.  I have GE541NB photoelectric smoke detectors in use.  These units are 4 wire and interconnected in a normal open state.  When I have the pin the smokes are connected to designated as a "Smoke Detector"  it registers as smoke is always detected.  I switched the for the smoke alarm function from normal open to normal closed and smoke is still detected......If I switch that pin to a regular Open/Closed switch things seem to work correctly, the smokes show up as open and if I apply smoke to any of them the switch goes to closed.  So what am I doing wrong here?

Thanks for any help you can provide.
