Installed alarm system working together in parallel

I like to keep the installed alarm monitored system using hardwire sensors (open and close contacts) and take sample from some hardware sensors and connect then to the Konnect module, this way I can also use smartthings to use the signal for animation, or alerts.

I tried and created a problem in which the existen alarm system failed to detect open door and disabling the alert. any ideas? Which module will work for this?
