DSC 4020 with PC4401 DVAC Card

[Martin Paterson <mpaterson@xxxxxxxx>]

Hello;
	I have an existing site that has a 4020 installed and is being
monitored by DVAC's (PC4401 installed).  Another client is moving into
the same site as well and would like to have there own security system.
  The existing client has no problem with sharing the current system
with the new client.  The decision to add the new client as a partition
on to the existing system was chosen.  We created a new account for the
new client and added it into there respective partition.  Unfortunately
It appears that the DVAC card can only support one account code from
what I could get out of the manual.  Any signal I generate on the new
partition always comes in on the original account.  Has anybody found a
way to add two account codes to the 4401 module and get it to match that
of the partitions
