It depends what else you need to page. We have a 5485 IP Paging unit and I disconnected it. The only useful purpose for the 5485 is if you are trying to page to an area that does not have the physical copper pairs needed to connect to the amplifier and page over the IP network OR if you want to be able to page other IP phones in a page group at the same time as the PA system. There is no option to page groups and overhead paging simultaneously. If you do not need to page other IP phones and just use it for PA paging I would recommend programming the E&M module through the RJ-12 port. It is much easier in my opinion.
For some strange reason Mitel has a 25 pair amphenol connector coming off the 5485 paging unit so you can use up a 66 block and space on your backboard, punch down 25 pairs in order to easily utilize 6 pinouts. My only guess it is like this is to swap out a DMP unit.
The 5485 does not have a speaker and has an external power supply. It is not PoE capable, must use external power supply.
In order to page to this unit you must program “direct page” and if desired add to a page group. When paging this device the access codes can be quite lengthy and the user must wait 5 seconds after paging a page group. I could be wrong but haven’t figured out a way around this.
2 scenarios:
EX 1 – Direct page unit by programmed ext number. Press programmed direct page button + EXT or FAC + EXT. So if you don’t have a direct page button you are dialing 6+ digits depending on config.
EX 2 – Page group in a group by itself or with other IP phones. Press programmed direct page button + page group number. So say you only have 1 page group (group no 1). Press direct page or FAC then 1... wait… 5 seconds… then ok now you can talk. I imagine it waits so long to make sure you are not paging a group above 1 digit(ex group 12). Or if you are paging from telephone that is setup in a default page group of the same group number then you can press direct page or dial FAC + # key. Still have to wait 5 seconds though.

11 BL/BK Page Control input
12 O/BK
Or you can you use the embedded method going into an amplifier and use a FAC to activate loudspeaker paging. No wait and it is instantly connected to the pager. We have a tone generator (Valcom V-2001a) before the amp because the Mitel tone is so short and almost nonexistent it cannot be heard before the announcement.
