Just having thoughts on this and the practicality of changing.

I currently have a Yale wirless alarm system, twice when on hols the
damn thing has gone off and a neighbour who has a key reset it for me.
I am seriously thinking about dismantling it and selling it on ebay and
replacing with stand alone PIR thingies which cost around £8 an item. So
could cover my house for say £50. This would also eliminate me having to
go up a ladder every 2 years to replace the batteries with the Yale system.

Anyone using just stand alone PIR alarms?
