...require 240v just like the hold fashioned (Honeywell) ones. I find this a bit strange. An alarm control panel will comfortably operate over 12v that is sourced via the main control box or a battery, but these for someone reason want 240v which they then convert locally into 12v. The current draw is identical so there's no reason for it. Is this simply because the manufacturers assume you will have the original (240v) wiring? I mean, wouldn't a better (future proof) to have versions that operate over 12v in the same way as your alarm control panel? New builds would benefit.
In any case, could some one please share a link to something I can buy online suitable for the above?
Thanks
