INSPECTION LOG

is used in conjunction with the

ARC-1 PC Interface software. It is used at the
factory for testing complex sequence of operations

with the help of a PC connected to the system, by setting up
a flag in the sequence of operation. Once the sequence of
operation is activated, the PC will display all the events that
occurred between the activation and the de-activation of this
flag, making complex sequences verification easier. The log
can also be printed for archiving.

Pressing on the key will illuminate the

LOG ACTIVATED LED

adjacent to the switch.

Not used.

SYSTEM SHUT-OFF

is a special function associated

with ICAF Extinguishing systems. Pressing on this
function key anytime during the discharge sequence

and then manually closing the water main supply control
valve will completely stop the flow of the foam agent. The

SHUT-OFF KEY ACTIVATED LED

adjacent to the switch will be

illuminated while the function is active.

Typically, to activate any function press and hold the key for
2 seconds. Press and hold the key again to return to its
normal status. Key status will also be indicated on the alpha-
numeric display bottom section as described earlier.

6. Local alphanumeric display

The

ARC-1

Analog Release Controller is provided with a

local alphanumeric display, model LAA, mounted on the front
door that provides detailed indications for status display,
operation and programming of the system. It is provided with
a soft membrane keyboard accessible by opening the front
key locked door. The alphanumeric display and the main
indicating lamps are visible through the door window at all
times.

Upon initial power up, the local sounder will be heard for
2 seconds then will automatically stop. At the same time, the
alphanumeric display will become momentarily blank and
then will show a scrolling

SYSTEM RESET

indication. It will

also momentarily display the

P&P IN PROGRESS

indication

while the system's plug and play routine is executed.

Note:

The plug and play routine is automatically verifying

system integrity and module placement at both the initial
start-up and system reset.

The start-up procedure should last only a few seconds,
after which, if the system is back under normal condition,
the alphanumeric display will show the

SYSTEM NORMAL

screen, similar to the one shown below:

Note:

Should the start-up routine take more than

2 minutes and system seems to be hung, perform a
cold reset by removing power to the unit and back. If
problem continues, contact your nearest

IRE

LEX

Authorized Distributor.

This screen displays the system configuration description
such as fixed discharge system in the example above
and the system status in a black window.
The black bottom line typically shows current date and
time on the left and right respectively. In the center, the
Function Keys status indicator code displays status of an
activated function for the corresponding key: A "1"
indicates a function is activated by Function Key F1, a "2"
for F2 and a "3" for F3. No change or a "0" indicates that
the function key(s) is (are) normal or not, assigned to any
special function. Refer to paragraph 5 for additional
details.
Depending on the specific menu screen, an alternate
bottom black line shows number of alarms, supervisory
and trouble events, followed by the current date and time
when an event is present.

Note:

All the alphanumeric display screens shown

throughout this manual are typical and for general
information only. Actual screen details may vary
depending on selected configuration and conditions.

Time and date on initial start-up will show default values
and will have to be adjusted by the user (see

MENUS –

ACCESS LEVEL 2

for detailed instructions). Furthermore,

time and date will return to the last event values in
memory every time the system power is completely
removed (both AC and battery stand-by).
Upon any event, the

SYSTEM NORMAL

screen will change

to the

SYSTEM EVENT

screen and show all current events

and their status.
Shown below is a flow chart describing in which order the
system keys must be operated in case of various events:

have been processed)
