Connect my wired alarm system to HA

Just wondering… I have an alarm-system in my house. fully wired. (door/window sensors and PIR’s)

Is there a way to connect these to HA too ?
Here’s a simple schema from the alarm- main unit.

Konnected interface board. Google it. I have one and it’s working perfect with my current alarm

You don’t have a communication module for it? Like Ethernet or anything like that?

Nope. it’s a pretty old system

Hmm, $99 is pretty high price I think. But thanks!

Short of replacing the main alarm board…or trying to write some sort of arduino device (plus having to code the serial commuunication)…I think Konnected is your only option.

RaspberryPi or arduino

You can move all alarm contacts over and input to GPIO ports
Siren you need to use some relay switched by Pi or other means to switch the relay

keypad no longer useful and just use HA Alarm

I used this and had good success.
I use my inwall speakers and send sound to Chromecast audio for siren and other sounders (the doorbell I wired into gpio)

My current home this was too much of pain since house was not fully wired and I moved to zwave everything
