Extinguishing Control Panel
Installation and Operation Manual

1 General
GST303/GST306 Extinguishing Control Panel (hereinafter called the control panel) is
designed for driving the executing units of a fixed extinguishing system.
Except for 3 extinguishing zones less, and some minor differences in appearance and
structure, GST303 is the same as GST306 in operation. We’ll take GST306 as an
example.
2 Features
The control panel can be directly connected to the loop of GST intelligent fire alarm
control panels (FACP) that are able to control associated fire suppression equipment to
achieve automatic control of gas release.
It can also control gas release devices independent of the FACP. When the FACP is
not working properly, it can still control extinguishing devices through emergency gas
override control in field or Start and Stop keys on the control panel.
This control panel is also able to monitor and alarm on short circuit or open circuit with
externals cables

4 Structure and Operation Principle
4.1 Structure
This control panel is surface-mounted on the wall. It contains main board, zone control
board, I/O board, filter board, Start key, Stop key and Power switch, etc. Appearances
of the GST303 and GST306 control panels are shown in Fig. 4-1.

4.1.1 Front Panel
Front panel of GST306 is consisted of start/stop control panel (including Start key, Stop
key and indicators), Power switch, Reset switch, and Manual Start key as shown in Fig.
4-2.
Fig. 4-2
Note: Power switch is only accessible when the door of the control panel is open.
Start key: Non-self-lock key. When this key is pressed, GST306 will send gas
release command to fire suppression devices immediately.
Stop key: Self-lock key. When this key is pressed, the already sent delay start
command will be stopped, and the control panel is reset to normal operation.
Run LED: Green. It illuminates when 24VDC power is applied to the control
panel and switched on.
In Delay LED: Red. It illuminates when the FACP detects fire and gives gas
release command, or field emergency gas override control is pressed and the
control panel enters delay start state.
Start LED: Red. It illuminates when start command is given (including

GST303 /GST306
Extinguishing Control Panel

immediate start and delay start) and remains illuminating after relay output is
activated.
Release Confirm LED: Red. It illuminates when corresponding zonal
pressure switch is activated.
Fault LED: Yellow. It illuminates when connecting cable between the control
panel and emergency gas override control or gas release warning indicator is
in short or open circuit; or when connecting cable between the control panel
and present primary or standby solenoid of cylinder is in short or open circuit,
or when power supply is lower than 20V.
Output Fault LED: Yellow. It illuminates when connecting cable between the
control panel and primary or standby solenoid connected with gas
extinguishing control relay module is in short or open circuit.
Standby LED: Green. Reserved for later use.
Stop LED: Green. It illuminates when stop command is sent out.
Power switch: Switching on or off the power of the control panel.
Reset switch: Pressing this key, the control panel will be reset, and all output
signals will be stopped.
Manual Start key: This key is to control manual keys on the front panel. The
manual keys cannot be operated when this key is disabled.
4.1.2 Internal Structure
Internal structure of the control panel is shown in Fig. 4-3 (taking GST306 as an
example). It shows the relative position of main board, zone control board, I/O board
and filter board, etc. Internal connection is shown in Fig. 4-4.

4.2 Operation Principle
The control panel works on multi-wire mode. It connects with external devices such as
solenoid, C-9317 Emergency Gas Override Control, I-9402 Sounder Strobe, C-9318
Gas Extinguishing Warning Indicator and C-9316 Gas Stop Indicator through multi-wire.
It can also be connected to polarity-insensitive loop of fire alarm control panel (which
should be able to control fire suppression devices) to form an extinguishing control
system integrating fire alarm and fire suppression.
5 Mounting and Commission
5.1 Unpacking and Inspecting
Check the items against the packing list. Open the package and check whether
installation and operation manual, key to the control panel and accessories have come
with the control panel. Then inspect the appearance of the control panel.
Check internal configuration with reference to Chapter 4. Check the connection of
different parts and make necessary records for use in installation and commission.
