The Acknowledge button is used to acknowledge each new
alarm/fault condition on a zone or circuit on the panel. When
pressed an ACK message is displayed in the text message
describing the alarm/fault condition.
The Next button changes the text message in the display to
the next alarm/fault/isolated zone or circuit.
By repeatedly pressing Next button, it scrolls through the list
of alarms/faults/isolated zones or circuits in the display.
The Reset button is used to reset zones in alarm in the
system after the area has been secured.
The Isolate button is used to isolate any zone that cannot be
reset. Non-resetable zones will continue to be registered on
the display as an alarm until rectified. For example:
SIMPLEX AUSTRALIA - Time of day - Bat: OK
Alarms: 02 Faults: 00 Isolated : 02
NOTE: Once a zone has been isolated it cannot be reset using the main reset
button. You must use the system reset key, KEY 5 (RST) located on the
keypad on the right of the panel.
The Brigade Test button is used to test the alarm call circuit
to the fire Brigade.
