OK - well the fire detection and alarm system needs separate containment - and as a quick answer, if you have phased or staged evacuation or anything that looks like a stay put procedure for selected key personnel then you will need an enhanced grade as defined in BS 5839-1 (it will refer you to allowable cable standards). Ditto if you need to send signals to any adjacent or adjoining facilities and/or if there are fire and smoke dampers in place that you need to control
