guishing system has an open or short circuit fault. A
separate LED on the control board inside the panel will
indicate which circuit is in fault.
3.18.10LAGE DRUK GASCILLINDERS
(GAS LOW)
This is a yellow LED which is normally OFF. It pulses
while the Gas Low input is active, clearing when the
input is cleared.
3.18.11HOGE DRUK VERZAMELLEIDING
(GAS TRAPPED IN MANIFOLD)
This is a yellow LED which is normally OFF. It pulses
while the Gas Trapped input is active, clearing when the
input is cleared.
3.18.12AFSLUITER ONJUIST (ISOLATION
VALVE ABNORMAL)
This is a yellow LED which is normally OFF. It pulses
while the Isolation Valve monitors an abnormal value
(nominally 10 kΩ load), to indicate valve stuck between
open & closed, clearing when the input is cleared.
3.18.13AFSLUITER DICHT (ISOLATION
VALVE CLOSED)
This is a yellow LED which is normally OFF. It pulses
while the Isolation Valve monitors a Closed value (nom-
inally 680R load), clearing when the input is cleared.
3.18.14HANDACTIVERING; STORING/UIT
(MANUAL RELEASE FAULT/
DISABLED)
This is a yellow LED which is normally OFF. It pulses if
the Manual Release zone input is in fault or the internal
circuit to the door mounted Manual Release is in fault,
clearing when the fault is cleared. A separate fault LED
for each circuit is also illuminated on the internal control
board. The Manual Release Fault/Disabled LED is illumi-
nated steady when the Manual Release facility is disa-
bled.
3.18.15BLUSSING UIT (EXTINGUISHING
DISABLED)
This is a yellow LED which is normally OFF. It is illumi-
nated steady when the Actuators are disabled. [Note:
When the actuators are disabled the Extinguishing
Sounder circuit is automatically disabled].
3.18.16DOORM. BLUSSING; STORING/
UIT (GAS RELEASED SIGNAL
DISABLED)
This is a yellow LED which is normally OFF. It is illumi-
nated steady when the Gas Released Signal output is
disabled.
3.18.17ALGEMENE STURINGEN
(SHUTDOWN OUTPUTS
DISABLED)
This is a yellow LED which is normally OFF. It is illumi-
nated steady when the shutdown outputs are disabled.
[All three 1st Stage, 2nd Stage & 3rd Stage shutdown
outputs are disabled together].
3.18.18BLUSVERTRAGING (SECONDS TO
DISCHARGE)
This is a 2-digit numeric display. It is normally blank.
When the pre-discharge timer is running, the remaining
seconds left to discharge are displayed.
In
CONFIG SLU
mode, the 2-digit display allows the
SLU type codes to be programmed into the panel (see
section 4.2.3).
3.19 Display Board - Bediening
The Display Board provides user controls via buttons
behind the membrane of the display board.
All buttons except for
TEST
(for Test Display) are disa-
bled until the
BEDIENING
key-switch is rotated to the
AAN
position.
The panel acknowledges a button press by sounding
the internal buzzer briefly.
The following controls are available:
3.19.1 SIGNAALGEVERS UIT (SILENCE
ALARMS)
This button silences the general sounder circuits and/or
silences the extinguishing sounder circuit when possi-
ble. Silencing of the extinguishing sounder circuit is
inhibited until the panel enters the Gas Released condi-
tion or the Abort input is activated.
The attached yellow LED is normally OFF. It pulses
when it is possible to silence any of the sounder circuits
and is illuminated steady to indicate silenceable sounder
circuits have been silenced.
3.19.2 SIGNAALGEVERS AAN
(RESOUND ALARMS)
This button allows previously silenced alarm circuits to
be resounded.
