MANUAL/AUTO switches is in an open-circuit condition, the system will enter the manual mode;
when all of them are in a short-circuit condition, the system will enter the auto mode.
It can be seen that the system will give priority to the auto mode when multiple LOCAL
MANUAL/AUTO switches are connected in parallel or to the manual mode when the said
switches are connected in series. For better practical application, the serial connection mode is
recommended.
Note: After detecting a compound fire alarm in the auto mode, the system will automatically
drive the electromagnetic valves, start the fire extinguishing devices; and after detecting a
compound fire alarm in the manual mode, the system will not drive the electromagnetic valves.

Terminal 21 on the master control board:
It is for the muting control of both the horn/strobe and
the alarm bell (for the AGND short/open circuit switch).
1)
Connection mode 1 should be selected for it. When connection mode A without an open circuit fault
detection function is selected, the jumper JP18 on the master control board should be set to the ON
position as shown in Table 3.1.2 and Fig.4.1, and the built-in termination resistors in the control
board should be used; and when connection mode B with an open circuit fault detection function is
selected, the jumper JP18 on the master control board should be set to the OFF position, the built-in
termination resistors in the control board should not be used and a 10K
Ω
termination resistor should
be arranged at the end of the circuit shown in connection mode B.
2)
A short circuit of the switch suggests a mute signal input and muting of both the horn/strobe and the
alarm bell. At this time, the switch is off, the muting is cancelled and the external muting cannot be
cancelled through the HORN/STROBE START/STOP button and the ALARM BELL START/STOP
button on the display panel. In case of an open circuit of the switch, the muting can be cancelled
through the HORN/STROBE START/STOP button and the ALARM BELL START/STOP button on
the display panel.
6.
Terminal 22 on the master control board: I
t is for the reset signal input (for the AGND short/open
circuit switch).
1)
Connection mode 1 should be selected for it. When connection mode A without an open circuit fault
detection function is selected, the jumper JP14 on the master control board should be set to the ON
position as shown in Table 3.1.2 and Fig.4.1, and the built-in termination resistors in the control
board should be used; when connection mode B with an open circuit fault detection function is
selected, the jumper JP14 on the master control board should be set to the OFF position, the built-in
termination resistors in the control board should not be used, and a 10K
Ω
termination resistor
should be arranged at the end of the circuit shown in connection mode B.
2)
A short circuit of the switch suggests a reset status of the system, and an open circuit of the switch
means that the system will enter the monitoring status.
7.
Terminal 23 on the master control board: I
t is for the accession of the local pressure feedback
signal (for the AGND short/open circuit switch).
1)
Connection mode 1 should be selected for it. When connection mode A without an open circuit fault
detection function is selected, the jumper JP15 on the master control board should be set to the ON
position as shown in Table 3.1.2 and Fig.4.1, and the built-in termination resistors in the control
board should be used; when connection mode B with an open circuit fault detection function is
selected, the jumper JP15 on the master control board should be set to the OFF position, the built-in
termination resistors in the control board should not be used, and a 10K
Ω
termination resistor
should be arranged at the end of the circuit shown in connection mode B.
2)
An open circuit of the switch suggests a normal status and a short circuit of the switch suggests a
pressure feedback signal input.
3)
When there is a pressure feedback signal input, the RELEASE indicator will have a drive output no
matter whether the electromagnetic valves have a drive output or not.
8.
Terminal 24 on the master control board: I
t is for the accession of the agent drop alarm signal
(for the AGND short/open circuit switch).
1)
Connection mode 1 should be selected for it. When connection mode A without an open circuit fault
detection function is selected, the jumper JP12 on the master control board should be set to the ON
position as shown in Table 3.1.2 and Fig.4.1, and the built-in termination resistors in the control
board should be used; when connection mode B with an open circuit fault detection function is
selected, the jumper JP12 on the master control board should be set to the OFF position, the built-in
termination resistors in the control board should not be used, and a 10K
Ω
termination resistor
should be arranged at the end of the circuit shown in connection mode B.
2)
A short circuit of the switch suggests an air cylinder agent drop alarm signal input and an open
circuit of the switch suggests a normal weight of the air cylinder.
In case of agent drop input, the electromagnetic valves will make no output regardless of whether there
is a fire alarm.
9.
Terminals 25 and 26 on the master control board:
They are for the accession of the detector
circuits.
1)
Terminals 25 and 26 are connected with detector circuit 2 and detector circuit 1 respectively. The
accessed detectors are common on-off heat detectors or smoke detectors. Generally speaking, the
two circuits are connected with a heat detector and a smoke detector respectively.
