Thanks for the input folks. Wired would be the preference. From what I can see I would need a few other things to get the Bentley working, a keypad, siren, battery backup, is that correct? The Optima appears to have more included, am I right in thinking it has battery backup? What about a siren, is that inside the unit as well as having the option for external? Please forgive my ignorance on this topic! Regards

Hi, I'm looking for a simple alarm system that just has two contact sensors for door / window, no desire to have PIR. I can't find any kit that offers this, and I wouldn't know what products to buy to build it my self. Do you have any suggestions? Thanks
