Hi Breezer, thanks for your reply, I did put a post on here Feb 27th (Upgrading Alarm System) asking that very question but got no replys, hence this post. Yes I agree, so can you recommend a system or kit I need to buy to upgrade. The system I have installed has siren, control panel which includes all the workings and keypad together. So all the cables come through the wall where the keypad and control box are situated now, beside my exit door, so would want it back in same place, if possible, I presume ?? Thanks again for your help, much appreciated.
