ARC determined:
This mode allows the ARC to override the settings put in by the
installer.
Irrespective of the address loaded by the installer, for each poll the
IRIS dialler will try first the Main Polling Engine, and retry if the initial
attempt fails. It will then try the Backup Polling Engine. On the next poll
this procedure will be repeated, i.e. the polling will be restored to the
Main as soon as it recovers.
For each alarm call, irrespective of the addresses loaded into the panel
by the installer, the IRIS dialler will first try the Main Polling Engine and
if this fails will immediately try the Backup Polling Engine.
The Main and Backup addresses will be automatically loaded into the
IRIS dialler when it polls in. If they are subsequently changed by the
ARC, the new addresses will be loaded on the next poll.
Note that this facility allows the ARC to hide the Main and Backup IP
addresses from the installer. A special “commissioning” Polling Engine
can be set up, and it is the IP address of this Polling Engine that is
given to the installer. On the first poll, the dialler will be reconfigured
with the actual Main and Backup IP addresses, unknown to the
installer.
Caution – the ARC operator must take extra care that valid IP
addresses are loaded as if the IRIS dialler has the wrong IP addresses
it will not be possible to communicate with it and a site visit will be
required. It is strongly recommended that if the setup is changed it is
tested on one easily accessible IRIS dialler before being applied to the
full community.
