yes I have heard of these did the price include a central station connection or is the price for bell only ?
Just to let you know you can get a Hkc (Irish Made) Panel and get a Text Dialler Fitted to it and it will text your Phone or others, when a alarm occurs .This saves on incurring central station costs yearly, to your goodself.Shop Around and make sure you get an alarm to the Nsai Standard 199 and get a certificate so you will get reduced home insurance .Good Luck
