1 General
GST-FT24N fire telephone panel is spe ialized for emergen y ommuni ation, builds up
onvenient and prompt 2-way ommuni ation in ase of fire and other abnormal onditions.
It is an indispensable devi e in fire prote tion system. The panel has features as below:
 Standard 3U stru ture, ra k mount installation
 24VDC power supply
 Re eiving and alling out with fire telephone handsets
 Networkable fire telephone panels a hieve internal ommuni ation
 Call from handset will be transferred to networked fire telephone panels automati ally
after not answered by the dedi ated panel
 The handset zones are fully monitored for fault of short ir uit and open ir uit. Panel
will show the fault by sound and indi ator.
 Failure of one zone will not effe t on other zones
 The network ommuni ation is monitored. When sub-panel fails to ommuni ate with
the main panel, the main panel will get the failure message and broad ast to other
networked sub-panels, both main panel and sub-panels will indi ate by sound and light
indi ation. When the fault happens on main panel, all sub-panels will show the fault
message, and meanwhile the network all will be inhibited.
 Re ord: The onversation between fire telephone panel and Handset or other fire
telephone panel an be re orded up to 15 minutes. The new ontent will over the old
one when the storage is full.

3.5 Digitron Displa
State Example Description
Network Free
On the main panel, the first digit
indi ates the quantity of panels in
the network, the last digit indi ates
its network address
On sub-panel, only the last digit will
show its network address
Network Call
The first digit indi ates the address
of the alling panel. The C at the
last digit means Calling.
Network
Conversation
The sample at the left shows the
onversation state between No.1
panel and No.2 panel. The others
will show “BUSY”
Network
Failure
The first digit indi ates the address
of failed panel. The E means Error.

5 Mounting & Commission
5.1 Initial Check
Che k the appearan e of the panel after open the box. Then power on and he k working
state.
5.2 Wiring Requirement
 Cross-se tion area of the power able not less than 1.5mm2
 Twisted-pair able onne ting panel and handset with SA not less than 1.0 mm2
 Twisted-pair able for the network with SA not less than 1.0 mm2
 The able sele tion must omply with lo al ode
Note: the impedan e of single line not more than 20Ω

5.5 S stem Commissioning
Please Make Sure the Correct Wiring before Commissioning.
Set panel address
 For standalone fire telephone system, the address an be assigned 1 or keep the
default setting
 There must be one panel assigned 1 in the network fire telephone system and register
other panels.
 Addressing step： Press a key between 1-8 key of front surfa e, then power on, press
the key over 2s, the number will be ome the network address of the panel. The
address will not be lost when the panel is swit hed off. The address will not be hanged
unless 1-8 key is pressed when the panel is powered on.
Note: The panel addresses an not be repeated in same network.
Register the Network Panels
After assigning the addresses, power on the sub-panels first. Then power on the main pane.
The main panel will register all networked sub-panels automati ally. Subsequently, the first
digit of the digitron will show the number of networked panels (in luding the main panel).
Che k whether all panels have been registered a ording to the shown number. If no
onsisten y, he k the wiring and repeat the above-mentioned pro ess.
The registration information is saved in non-volatile memory, will not loss on power off. The
registration should be arried out again in ase adding or removing network panels.
Not ne essary for registration on sub-panel.
Test Functions
Test the other fun tions a ording to Operation Manual after ommissioning.

The panel an make all to handsets in other zones when a onversation is underway.
6.2 Handset Call Panel
On e the handset is pi ked up without being alled, the all will go to the panel. The panel
will ring with “Call” and “Ring In” LED fast-flashing. Press the relative key and enter into
onversation with “Call” being on, “Ring In” goes out. Meanwhile, if there are other zones
alling panel, “Ring In” will keep fast-flashing. Hang-up the handset or press the relative key
on the panel will stop the onversation.
6.3 Call Panels in Network
If the handset all is not answered by the panel within 12s, and the network is available, the
all will be transferred to other networked panels. Press “Network Call” and start the
onversation. Stop the onversation by handset hanging up or “Network Call” repressed.
6.4 Panel to Panel Call
When network is available, press “Network Call” will send the all to entire network with the
LED indi ator fast-flashing. Meanwhile, the digitron on other networked panels will show by
flashing “X — —C” (X- The alling panel), the “Ring In” and “Network Call” LED will fast
flash with ringing sound.
Press “Network Call” button and then start the conversation. The digitron of the panels not attending
conversation will show “BUSY” and the ring tone stops. Panel in conversation will show the
address of the other one. Either part can stop the conversation by pressing “Network Call”.
6.5 Inquire about conversation record
Press “PLAY” key of the ele tri re order, then the re ord will be played. Press
“FORWARD” and “REWIND” to swit h the ontent rapidly and press “■” to stop.
Ele tri re order will start or stop re ording automati ally along with the onversation, The
new ontent will over the old one when the storage is full.
7 Troubleshooting
7.1 Zone Fault
The zone fault shows an open or short ir uit between panel and handsets, or the End of
Line Resistor not onne ted. Che k the able by multi-meter, whether the resistan e is

roughly 10kΩ.
7.2 Network Fault
The panel shows network fault when there is any of the panels powered off or network able
fault. Che k the malfun tion panel and wiring.
