I need to make up a drawing based on a project spec for a fire alarm system. The specs call for the use of two CAT5 cables that will run from the phone board to the alarm panel. Each line will be connected to a RJ31X jack for the alarm dialer. This tells me the line in form the phone comany and the in house phone line will be in the same cable. I presume that there is a color standard for the CAT5 cable used in conjunction with the jack. Is there a particular color order for the incoming and in house phone line tip/ring?
