3. Keyboard - System main control keys
Panel is provided with a membrane type keyboard as shown
on the previous page. Local sounder will beep once every
time a valid control key is depressed. Sounder will beep
twice anytime an invalid entry is made or user is scrolling too
fast with the navigation keys. Various system main control
keys are described below:
ACKNOWLEDGE
:
Every
new
event
must
be
acknowledged. Depressing this key will acknowledge
alarms, supervisory and troubles while in their respective
events screen. The panel has alarm and trouble resound
with lamp flash on subsequent events with alphanumeric
annunciation. The flashing lamp turns steady and the local
sounder is silenced once all events have been
acknowledged.
As shown above, before any event is acknowledged, the
alphanumeric display shows the three letter code 'NAK' in
front of the event description. Once acknowledged by the
user, this code changes to 'ACK'.
By default, each event has to be acknowledged
independently. The user can define in the
TECHNICAL
SETUP -
PARAMETERS
menu that holding the key for 2 seconds will
acknowledge all the current category of events at once.
When this feature is enabled, a second beep will confirm the
command has been executed and all events will display the
code 'ACK'.
ALARM SILENCE / ACTIVATE
:
When alarms are
sounding, pressing once on this key will turn off all
the audible devices connected to the silenceable notification
appliance circuits (but not the releasing circuits). The
AUDIBLES SILENCE
lamp will illuminate.
When alarms are not sounding, pressing and holding the key
for 2 seconds will activate the alarm condition, the notification
appliance circuits and the system alarm relays but not the
releasing circuit(s). The
ALARM ACTIVATE
function of the key
is always available and both functions are latching, so will
require a
SYSTEM RESET
to clear.
SYSTEM RESET
:
The
SYSTEM RESET
key will only
operate while the system is either displaying a normal
operating screen for lamp test or once all events in the
system event screens have been acknowledged. Trying to
reset the system while any event is still not acknowledged
will silence the system buzzer momentarily, then make it
beep twice and finally continuously again. Once all events
are duly acknowledged, a full reset sequence should take
only a few seconds to complete.
Under normal conditions, pressing on the
SYSTEM RESET
key make the local sounder beep once and will also
perform a
LAMP TEST
function.
Under alarm, supervisory or trouble conditions, once all
events have been acknowledged and cleared, pressing
once on this key resets the system and breaks power to
all initiating device circuits, 4-wire smoke power and
option boards. It will also clear any activated output
circuits. Should any alarm or trouble still exists after the
reset, they will automatically re-activate the panel
(subsequent alarm function).
4. Keyboard - Menu navigation keys
UP / PREVIOUS
:
Pressing on this key once will
scroll up the highlight to the
PREVIOUS
line on the
alphanumeric display or increase the value of a digit.
Pressing and holding the key will scroll fast up through
the values of a digit.
DOWN / NEXT
:
Pressing on this key once will scroll
down the highlight through the
NEXT
line on the
alphanumeric display or decrease the value of a digit.
Pressing and holding the key will scroll fast down through
the values of a digit.
LEFT ARROW
:
Pressing on this key once will scroll
the cursor (underscore) sideways to highlight the
PREVIOUS
digit or field on the alphanumeric display.
RIGHT ARROW
:
Pressing on this key once will
scroll the cursor (underscore) sideways to
highlight the
NEXT
digit or field on the alphanumeric
display.
Every time a valid navigation key is depressed, the local
sounder will beep once. Holding the
UP
or
DOWN
key
depressed for 2 seconds will return the cursor (highlight
on the active item) directly up to the first or last item or
field of any list, depending on the key selected.
The
UP
or
DOWN
keys will also scroll up or down a full
page in a list of items, thus accelerating navigation when
used the same way.
Depressing the same key again when already at the
beginning or the end of a list will make the local sounder
beep twice to indicate an invalid entry. Any invalid entry
will also make the sounder beep twice.
ENTER
:
This key is used to make and confirm
choices in the various user menus. It is also used
to validate an entry or select an option.
While within the
SYSTEM NORMAL
or
SYSTEM EVENT
screens, pressing and holding the
ENTER
key for
2
seconds will give access to specific system data
screens.
First screen displays the
SENSORS LIST / TEMPERATURE
as
shown below, where up to 6 sensors pressures can be
displayed. The cursor also highlights the screen name
being accessed in the first line as shown below:
