If you read the manual carefully, it is talking about connecting to a loop start
trunk port (FXO), not a station port (FXS). The paging unit is not expecting
ring voltage and may get damaged if you send it. In all of the scenarios it
outlines, the paging system is generating the battery and dial tone and
expecting the phone or the PBX to simply go off hook and then dial a zone.
You’ll need an ATA with an FXO port (like a Grandstream HT813) and then dial the
desired zone number out that trunk.

Based on how I read the manual if you connect the TIP and RING of the ATA to the
right pairs you should be able to send a call to the paging box. It looks that
when the page call is picked up by the paging system you would then press a zone
1-9 or 0 for all. The page would then bridge to the desired zone. the page
would complete when the call is hung up. You would likely need to make sure the
ATA is using current loop disconnect or reverse to ensure hang-up.
I think it should be the PABX config using the Figure 3 configuration.
Best of luck

Does anyone have an (overhead) paging system that they like that works with SIP?
We’ve got a client with an old paging system that (supposedly) just takes an
rj11 POTS connection, but when we put an SPA Cisco adapter on it, it doesn’t
auto-answer the call, so paging never happens.
Does it expect to see a POTS line with battery on it?
Then a Cisco or other ATA that would work to supply service to a POTS phone
should work
OR:
Does it expect to see a POTS connection from a PBX trunk, and supply battery TO
the trunk?
Then you would need a Cisco or other ATA with an FXO connection.
Both types of paging systems have been made and both styles of connections have
existed through the last 30 + years, and since you haven't revealed the
brand and model of paging system it makes troubleshooting difficult.
Using the existing system can be made to work
I use a very old Harris PagePak VS that was used with a Western Electric Horizon
system back in the dark ages with Asterisk
