I General
GST301 Extinguishing Control Panel (hereinafter called the panel) is a stand-alone
panel intended for use with gas extinguishing systems. The function of the panel is to
monitor zones or areas for fire conditions and give an appropriate audible/visible
indication. The panel also provides a facility for initiating the gas release to put out fire,
both manually and automatically.
II Features
GST301 Extinguishing Control Panel has 2 detection zones to achieve double-knock
function, and a normal detection zone for extra usage. With C-9317 Emergency Gas
Override Control (emergency start/abort button), gas release can be controlled in field.
III Technical Specifications
1 Operating Voltage: 220/230VAC,50/60Hz
2 Power Consumption≤20W (Monitoring Mode)
3 Battery Requirement: 2X12VDC, 7Ah
4 Battery Operating Time:
a) 24 hours monitoring and half an hour alarm if the current of AUX power
output is 0mA.
b) 8 hours monitoring and half an hour alarm if the current of AUX power
output is 100mA.
5 AUX Power Supply:100mA/24VDC
6 Sounder Output: 0.5A/24VDC
7 Release Output: 2A/24VDC, pulse
8 Battery Charge Current: 300mA
9 Maximum Detectors in Each Zone: 15
10 Maximum Number of C-9317 Emergency Gas Override Control: 4
11 Operating Environment:
Temperature: 0°C～40°C
Relative Humidity:≤95%, non condensing
12 Dimension: 300mmX350mmX110mm
13 Mounting Hole Distance: 260mm
IV Structure and Operation Principle
1 The panel is wall-mounted. It mainly consists of a cabinet, a main board, a display
board, and a transformer. Its structure is shown in Fig. 1.

2) Indicators
Power Green. Lighted when power supplied.
AC Fault Amber. Lighted when there is AC Fault.
Batt Fault Amber. Lighted when battery voltage is below 5V.
Gas Release Red. Flashes during delay time. Lighted after gas
released. Extinguished by reset.
Fire Red. General fire indication. Lighted by any fire signal.
Extinguished by reset.
Silence Green. Lighted if the panel is silenced. Extinguished when
it re-sounds.
Auto Enable Green. Lighted if the panel is in automatic mode. Off for
manual only mode.
Evacuate Green. Flashes when “Evacuate” key is pressed.
Extinguished by reset.
DELAY TIME Red. Indicating the time (in second) before gas releasing.
Zone1 ACTIVE Red. Flashes when Zone1 is in alarm. Lighted steadily
after it’s silenced. Extinguished by reset.
Zone1 Fault/ISO Amber. Flashes when Zone1 has any fault. Off when the
fault is removed. Steadily lighted when Zone1 is isolated.
Zone2 ACTIVE Red. Flashes when Zone2 is in alarm. Lighted steadily
after it’s silenced. Extinguished by reset.
Zone2 Fault/ISO Amber. Flashes when Zone2 has any fault. Off when the
fault is removed. Steadily lighted when Zone2 isolated.
Aux Zone ACTIVE Red. Flashes when the AUX Zone is in alarm. Lighted
steadily after it’s silenced. Extinguished by reset.
Aux Zone Fault/ISO Amber. Flashes when the AUX zone has any fault.
Steadily lighted when the AUX zone is isolated. OFF
when the fault is removed.
Cylinder ACTIVE Green. Flashes when the release output is active.
Extinguished after output finished.
Cylinder FAULT/ISO Amber. Flashes when the gas release output circuit has
any fault. Lighted steadily in isolated mode.
Start ACTIVE Green. Flashes when the “START” key on the panel or the
Emergency Start Button in field is pressed.
Start FAULT Amber. Lighted by fault with Emergency Start Button
Circuit. Extinguished when fault removed.
Stop ACTIVE Green. Flashes when the “STOP” key on panel or the
field Emergency Abort Button is pressed.
Stop FAULT Amber. Lighted by fault with Emergency Abort Button
Circuit. Extinguished when fault removed.
Pressure Switch ACTIVE Green. Lighted if the pressure switch is active (gas
released) or after gas release output started (no pressure
switch). Extinguished by reset.

Pressure Switch FAULT Amber. Lighted by fault with pressure switch circuit.
Extinguished when the fault is removed.
Sounder 1 ACTIVE Green. Lighted when sounder 1 output is started.
Extinguished when sounder 1 output is stopped.
Sounder1 FAULT Amber. Lighted by fault with sounder 1 Circuit.
Extinguished when the fault is removed.
Sounder2 ACTIVE Green. Lighted when sounder 2 output is started.
Extinguished when sounder 2 output is stopped.
Sounder2 FAULT Amber. Lighted by fault with sounder 2 Circuit.
Extinguished when the fault is removed.
3) Keys & Switches
Silence Stop all sounder outputs and local alarm (panel buzzer
will beep at 0.5s ON & 9.5s OFF mode). Sounder outputs
will be resumed by new active events (fire/start/pressure
switch action) or new fault signal or by pressing
“Evacuate” key. If delay timer is running, local alarm will
not be stopped, and sounder outputs will be resumed
within the last 15 seconds.
Reset Clear all inputs, indications and outputs.
Lamp Test Check indicators and the buzzer.
Auto Enable Enable the automatic gas release function by fire alarm of
two detectors. If this function is not enabled, the gas
release will not be started even if fire is detected by
detectors.
Evacuate Start the two sounder outputs. Stop by reset.
Control Enable Manual control authorization. In disable mode (position
“0”), only “Lamp Test” and “STOP” keys can be operated.
In enable mode (position “1”), all keys can be operated.
Primary/Standby Switch gas release output between primary and standby.
START Manual release control button.
STOP Stop delay timer (keeping remained time shown). Stop
Sounder2 output. Inhibit automatic gas release output .
ISO1～ISO4 Logically isolate corresponding terminals. Available for
Zone1, Zone2, AUX Zone and Cylinder. But “ISO4” is only
functioning for automatic gas release. The cylinder can
still be discharged manually even if it is isolated.
Sound indication: Alarm sound is provided by 70dB~100dB buzzer.
