ELK M1XRF2G to ELK ELK-M1XRFTW

[kccustom]

Howdy been a while since I had any questions,
 
Has anybody went from ELK M1XRF2G to a ELK ELK-M1XRFTW or can I just add the TW to my system?
 
I am going to start adding the two way smoke alarms.

I haven't specifically looked into this, but I'm pretty certain that the system can handle both on the same system as long as you are careful with assigning sensors to the appropriate zones.

I believe it can be done, however I believe it's not recommended in the FPN's of the 2 way receiver docs.
