Seeking advice to convert old alarm but retain parts

Hi,

I have an old Intellisense alarm panel (around 20 years old) with the following components:

  • Outdoor strobe/siren
  • Indoor siren
  • Two keypads (not needed)
  • Five motion sensors (no door/window sensors)

I want to replace the panel while keeping the motion sensors, strobe, and both outdoor and internal sirens. Initially, I plan to control the system via an app (e.g., SmartThings or similar) and may later add a tablet to replace the keypad. I also wouldn’t mind the ability to add a wireless door relay in the future - can you add wireless sensors to Konnected hardware?

I’m open to suggestions to do this in a very cost-effective way. I am competent on the hardware side, i.e wiring, fault finding etc.

Appreciate any ideas to convert this old beast.

Can anyone assist?

I’ve just setup home assistant and I’m keen to integrate Konnected.

Thanks
