i-on40 Installer Mode Programming
Page 81
Once Downloader is connected to the control unit then it
has access to all system programming. If you wish to
provide secure access then use either Call Out Only or
Secure Callback. Please note that you cannot use Secure
Callback with Local connection.
Call Out Only.
Someone must start a call to the remote PC manually
from within User Menu (select User Menu – System
Config – Call to Dwnldr).
Secure Callback.
When the remote PC calls, the system waits for the
set number of rings (see "Rings to Answer") and then
answers. The remote PC sends a control unit ID, the
Downloader software version, and indicates which of
the two Downloader Telephone Numbers to use (see
“Phone Book” below). The system checks that the
remote PC is sending the correct control unit ID, and
is using the correct Downloader software version. If
these items don't match then the system hangs up. If
the items do match then the system hangs up and,
after a short delay, the system seizes the telephone
line and calls the PC using the indicated Downloader
Telephone Number.
Notes:
a) Secure Call Back must be Disabled until the first
“attended” upload has been performed. This first
upload can be carried out either from User Menu, or
from Installer Menu.
b) Secure Call Back mode does not comply with
EN50131.
Unattended.
The control unit answers as soon as the number of
rings set in "Rings to Answer" or "Answer on One
Ring" have elapsed.
Notes:
a) The Downloader operator can choose to use
Secure Callback, even though the alarm system is
programmed for Unattended Mode.
b) Unattended mode does not comply with EN50131.
