I suggest checking with your local dealer, but think that it'll
probably be a category 1. You might find it helpful to check the
Thatcham web site
(http://www.thatcham.org/security/index.jsp?page=75), which includes
categorised lists of security devices in pdf. The category 1 list
appears to support my thinking.
