2. 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).

3. 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:
