Fig. 4.8 1 ) Zones screen and options available pressing 3-Zone
SET / UNSET
Pressing 3-Zone in the Maintenance or the Engineer level it is possible to Set or Unset
parts of the system.
The number of channels that may be Unset will never exceed 50% of the total
channels/relays number or 64 channels/relays, whatever happens first.
NOTE:
The Engineer level is allowed to Unset the WHOLE system, for the complete system
maintenance period. Trying to Unset the zone, a message will come out warning the
exact number of channels and relays that are about to be unset. If confirmed by
pressing Enter key (OK), then the zones window will show the unset status of the zone:
TEST / EXIT TEST
This will put to TEST mode or take out of the TEST mode the selected zone. It is
possible to put in TEST mode just parts of the system at user level “Maintenance” or
“Engineer”.
If more than half of the system selected, a warning screen as below will pop-up. A
screen message came out trying to put in Test/Maintenance mode the only zone
defined.
Until the number of zones to put in Test/Maintenance mode does not exceed the
defined limits (50%), the selected items will change the status into TEST.
Only the ENGINEER user is authorized to set under Test Mode the whole system. By
pressing ENT on the Test command, a new window will appear showing the number of
channels (detectors or output) that you are going to set under Test mode. To confirm press
ENT (OK). A
new window will appear to show the list of system’s zone marked with TST.
NOTE: The Zone TEST function is aimed at helping the Engineer during the Start Up. Indeed, after
the system has been switched on and the Control panel programmed, some communication faults
may arise from the remote Input modules or detectors connected on the RS485 buses. This
situation would generate a large amount of Faults (FLT) that could hardly be managed and would
require all Faults to be acknowledged before starting an adequate troubleshooting routine.
The Zone TEST mode allows to overcome this situation the following way: select the Test Mode, the
system zones and automatically all detectors belonging to these zone are set in test mode.
