Updates allow you to use some new devices that come out and fix any issues , although mostly I only needed to update for devices , firmware seems stable otherwise Yes, I'm in Ireland. I presume firmware upgrades can be installed via an RS232 serial connection to a laptop or similar, but you have to be a professional installer to download them from the manufacturer's website. I'm curious though what constitutes an alarm condition on a sensor. I.e how long contacts have to be open in order to trigger the panel. If this was relatively long, it could make the panel more immune to transients. A magnetic contact/ PIR contact would probably open for 100ms. A transient could be shorter, but the software might detect it if it's scanning everything rapidly. On a couple of occasions with my old panel, a zone triggered with the panel armed when I pulled out a mains plug. The alarm cable was quite close to the mains cable though.
