2.  Determine if the Old Room Stations are: 

    Vertical Stations (V) or 

  Horizontal Stations (H)  Go to RETRO  Room Stations Page ▸

3.  Look at your Front Doorbell Station, decide on replacing with plastic, metal or a Smartphone Doorbell Option.

Things to keep in mind:

  • If it is a 2 wire system at the front door get the adaptor *RETRO-DBB (click here, scroll down to read description)
