HKC Alarm (Ireland)

Hi there,

Has anyone here got experience working with HKC Alarm panels. I’m based in Ireland and they are very, very common here. It’s a closed system as far as I can tell, with no local API or developer options available.

I’m speaking to Konnected about their integration kit, but I wanted to check with this group if anyone has a more native integration solved which retains the existing keypads etc.

Many thanks in advance!

Hi Chris, I’ve looked into this a fair bit but HKC actively push to ensure no 3rd party integration on their platform. If you are using an older panel 8/12 or 6/10, I have reverse engineered a good chunk of the serial protocol and there has also been a project to emulate a keypad using an Arduino and ethernet sheild. All these older panels have a green backlight to the keypads.
Their newer ones (with a blue backlight) is the 10/70 family and this is where they changed all the protocols. Up to firmware version 3 it was possible but much harder. Since firmware version 4 they have encrypted the serial communication. It is possible to send a dummy data packet over the serial and get an active log event which could possibly be used to make a home assistant integration. Assa Abloy bought out HKC a few years back and they won’t entertain the conversation of linking with 3rd party equipment.

Thanks so much for the comprehensive response! I’ll check in on the model number of the HKC alarm panel.

Have you used Konnected with HKC alarms? I can see from that a number of people have managed to do it, I’m just not clear on the part list to extend the HKC with Konnected.

Hi Jamie - any chance you have this posted somewhere to have a look at? I would be interested in giving this a try. I too was/am considering a connected kit, but would give a shot to interfacing with the existing with an arduino if I could.
