We have an alarm fitted (came with our new build flat), does provide some reassurance (ground floor zone 2 flat) it's not monitored so a dummy box would do the trick I think.
When I had some sensors changed the firm that did it told me never to tell your insurer you have one, as if you did get broken into and had forgotten or not bothered to set it that insurers would use that as a way of not paying out.
