assigned. Once logged in, place or receive one-way page announcements to/from other users who
are logged in to the same PTT group.

be received. To restart the monitor circuit, the external contacts must be deactivated and the Alarm
Ring signal terminated.

is activated. A system contact also can be assigned to act as a Door Open contact.
