Operating Instructions - Zone Functions
Page 7-10 19 April 2002 Issue 2.38
OPERATING SEQUENCE - NETWORK ZONE RANGE (CONTINUED)
Ancillary Control Zones only, press:
All Zones, press:
The LCD will display the network zone range with a message saying "Network Command
Sent". After a brief period, the message should change to "Network Command Accepted".
Refer to Section 2.5.6 for more details on these and other possible LCD display messages.
Note that if the remote F4000 is unable to de-isolate all of the zones due to some of them
having an alarm or fault status, an exception message can be received indicating this. Refer
to Section 2.5.7 for a discussion of Exception Messages.
7.2.7 NOTES
(i) The effect of the isolate/de-isolate command is dependant upon the receiving FIP
type, eg. which zones will be isolated/de-isolated, how a zone is affected by
isolation/de-isolation, and so forth.
(ii) If an F4000 receives a network isolate/de-isolate command:
(a) Isolated zone(s) will register and indicate alarm and faults but are prevented
from operating system outputs.
(b) If the zone is in Auto-Reset mode, a zone de-isolate command will exit Auto-
Reset mode and leave the zone isolated.
(c) An un-silenced alarm indication will go steady on isolate and any alarm will
become unsilenced on De-Isolate.
(d) For zone range de-isolate, zones that are in Alarm, Operate or Fault will not
be de-isolated, and at the end of de-isolation the F4000 will send an
exception message to the source of the command indicating that not all zones
were de-isolated.
(iii) Isolate/De-Isolate commands to network zones that are on the local panel will be
implemented as if the command has been entered using the local zone numbers. The
network will not be used, and no network messages will be displayed.
