I'd suggest the the new gem has an alarm function, it maybe able to be configured with IDS to remove the alarm function.

But without plugging it in and checking I wouldn't be able to say for sure.

I once had a look at a Fiesta ST that was configured for LHD and with auto wipers and lights, which it didn't have!

Even replaced the gem and configured to RHD and without the auto wipers/lights.

In the end the Ford field engineer had to come down (twice) and sort it out with the As built data as the upgrade to IDS had taken away the ability to do that..
