7.2.4 NOTES
(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)
Any fault indication is unaffected by Zone Isolate/De-Isolate.
(d)
An un-silenced alarm indication will go steady on isolate and any alarm will become
unsilenced on De-Isolate.
(f)
For zone range de-isolate commands, any zones that are off-normal, i.e. Alarm,
Operated or Fault, will not be de-isolated, and at the end of the command the LCD
will display "Not All Zones De-Isolated". Use the Zone Status search functions to
determine which zones did not get de-isolated.
