Key Function
ALARM
ACK
Acknowledges any unacknowledged fire
alarms in the system, and scrolls
through the alarms in the active Alarm
List.
SUPV
ACK
Acknowledges any unacknowledged
supervisories in the system, and scrolls
through the supervisory conditions in the
active Supervisory List.
TROUBLE
ACK
Acknowledges any unacknowledged
troubles in the system, and scrolls
through the trouble conditions in the
active Trouble List.
ALARM
SILENCE
Silences any silenceable output types
(generally all audible notification appli-
ances).
SYSTEM
RESET
Allows the operator to reset all alarm
notification appliances and controls,
remove alarms from the Alarm List,
silence all silenceable outputs, reset
detectors, and return the system to a
normal state (provided that no alarm,
supervisory or trouble conditions are
present). The display indicates that a
reset is in progress and whether or not a
reset completes successfully.
Pressing the <SYSTEM RESET> key
will only attempt to return the system to
a normal, non-alarm state. All outputs
that were activated by the alarm will
remain active until all alarm inputs have
been restored and the reset was able to
successfully complete.
An open circuit fault on a Class A NAC
does not require a System Reset to
restore to normal.
Open circuit faults on the optional City
Connect module are cleared with a sys-
tem reset after the circuit has been
repaired.
MENU
The Menu key always brings you to the
top of the main menu structure unless
you are in the Programming menu.
FUNCTION
The Function Menu is displayed when
the <Function> key is pressed at the
high-level status screen. Use the <Previ-
ous> and <Next> keys to scroll through
the list of functions. The function key
provides access to commonly used con-
trol and display functions.
DISABLE/
ENABLE
The <Disable/Enable> key allows the
operator to quickly disable or enable any
point that is currently displayed. This key
is passcode protected. A confirmation
screen is displayed requesting <Enter>
be pressed before the actual enable or
disable is performed.
EXIT/
CLEAR
The <Exit/Clear> key is used to back out
of menus or displays and return to the
top-level menu structure. Where possi-
ble, the <Exit/Clear> key backs out one
level at a time. There are cases, how-
ever, that the Exit/Clear key will return
the operator directly to the top-level
menu.
ENTER
The <Enter> key is used to confirm
selections. When pressed, this key pro-
vides additional information about the
point shown on the display. In a pro-
gramming screen, pressing <Enter>
indicates that the information on the dis-
play is correct and can be accepted. The
<Enter> key is used in various other
places within the menu structure, always
for this same type of operation.
RIGHT/LEFT
ARROWS
The right and left arrows are used in
screens with multiple choices. The keys
advance the focus (square brackets [ ])
from field to field.
PREVIOUS/
NEXT
The Previous & Next keys are used to
scroll through the system lists, historical
log, point database, etc. The <Next> key
selects the next display screen in
sequence, and the <Previous> key
selects the previous screen. These keys
are also used to view additional informa-
tion about abnormal points or in viewing
historical logs.
