1X-E4 Series Operation Manual
If there is a defective device causing false alarms in zone 4 of panel 1, you can
disable it and keep some detection active (zone 4 of panel 2 operational). The
zone 4 yellow LED will activate in both panels. Afterwards, an alarm in zone 4 of
panel 2 will cause both panels to activate and the zone 4 red and yellow LEDs in
both panels will be active.
Pushing Enter for 3 seconds at panel 1 will cause the red LED indication of zone
4 to disappear, indicating that the control panel has zone 4 disabled. At this point,
you will know the alarm is from zone 4 of panel 2. You can confirm this by
pushing Enter for 3 seconds at panel 2. In this case, the yellow LED indication
disappears.
