r/FireAlarm

If i were to start up a new fire alarm company when i am done with my apprenticeship and when i get my licenses and documents all together. What would your guys opinions be on be partners with potter and mircom for fire alarm? Notifire is to difficult and basic. I was thinking about autocall but i am not sure yet. Kidde est is really difficult especially as a new owner especially in the area where i am at, And the same thing for siemens. What brands would you guys use? Brands that are less difficult and that are good quality for high end buildings to be partners with?
