SMCSM10-Z Smoke Alarm Connectivity

These are newer smoke alarms (mfg 2016) previously paired with the home security system we recently cancelled service with. They say they work with zigbee and we have successfully been able to get the other devices we had with the previous security system (door locks, window sensors) to pair up with SmartThings for use with Alexa. Does anyone have any idea how to sync this smoke alarm with SmartThings app and add it as a “thing”?

It’s possible the device supports zigbee, but not the zigbee home automation profile v1.2, which is the implementation of zigbee that SmartThings supports.

Spec sheet on the manufacturer’s website isn’t all that specific.

Any further exploration on this? Were you able to get it paired?
