March 14, 201115 yr To be precise you really need to measure what your system is drawing, or go for the maximum size the manufacturer recommends
March 14, 201115 yr A 3amp or 7 amp will do fine..these are slightly dearer , but last longer. http://www.securitywarehouse.co.uk/catalog/index.php?main_page=product_info&cPath=36_46&products_id=113
