Smoke, Heat, multi-sensor (Smoke + Heat) and motion detector's manufacture

Hello
I want to ask about manufacturing fire detection sensors because we will make a production line for assembling these detectors in Egypt and I want to know if we can make a partnership with BOSCH to supply the detectors modules or it's better to start ourselves from zero? what do you think?
Also I need to know what are the suitable solutions that BOSCH introduce regarding to that.

Thanks
