4.2.3 Description of the input terminals on the master control board
1.
Terminal 17 on the master control board: I
t is for the input of the MANUAL RELEASE button (for
the +24V short/open circuit switch and the self-locking switch).
1)
Connection mode 2 should be selected for it. When the connection mode A without an open circuit
fault detection function is selected, the jumper JP21 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 JP21 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 manual release signal input and
the necessity of using the
self-locking switch
. In order to strengthen the anti-jamming level, it is necessary to maintain a
short circuit state from the start of delay to release, or else only horn/strobe output, alarm bell output,
single fire alarm output and compound fire alarm output will be available and the electromagnetic
valves will not operate.
2.
Terminal 18 on the master control board: I
t is to access the MANUAL FIRE ALARM button (for
the +24V short/open circuit switch and the self-locking switch;
To connect the terminal MANUAL
FIRE ALARM button 1
).
1)
Connection mode 2 should be selected for it. When the connection mode A without an open circuit
fault detection function is selected, the jumper JP19 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 JP19 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 fire alarm signal input.
3.
Terminal 19 on the master control board: I
t is for the accession of the LOCAL EMERGENCY
STOP button (for the AGND short/open circuit switch and the self-locking switch).
1)
Before the delivery of the fire alarm controller, terminal 19 has been shorted to ground
through a black conductor (the factory default). This black conductor should be dismounted
when the LOCAL EMERGENCY STOP button is accessed.
2)
Connection mode 1 should be selected for it. When connection mode A without an open circuit fault
detection function is selected, the jumper JP20 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 JP20 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.
3)
A short circuit of the switch suggests a normal status and an open circuit of the switch suggests an
emergency stop signal input and the necessity of forbidding the output of an electromagnetic valve
driving signal.
4.
Terminal 20 on the master control board: I
t is for the accession of the LOCAL MANUAL/AUTO
switch (for the AGND short/open circuit switch and the self-locking switch).
1)
Before the delivery of the fire alarm controller, terminal 20 has been shorted to ground
through a black conductor (the factory default). This black conductor should be dismounted
when the LOCAL MANUAL/AUTO switch is accessed.
2)
Connection mode 1 should be selected for it. When the connection mode A without an open circuit
fault detection function is selected, the jumper JP16 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 JP16 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.
3)
A short circuit of the switch suggests an automatic signal input and the switching between the auto
mode and the manual mode can be realized at this time through the MANUAL/AUTO button on the
display panel; an open circuit suggests a manual signal input, and the system is in the manual mode
at this time, switching through the MANUAL/AUTO button on the display panel cannot be realized
and external manual operation is preferred.
4)
Generally speaking, only a LOCAL MANUAL/AUTO switch is connected to terminal 20 on the
master control board for setting the manual/auto mode of the system. However, on some special
occasions where it is necessary to connect multiple LOCAL MANUAL/AUTO switches, either of the
following two methods may be used.
a.
Make all LOCAL MANUAL/AUTO switches connected in parallel. When any of the LOCAL
MANUAL/AUTO switches are in a short-circuit condition, the system will enter the auto mode;
when all of them are in an open-circuit condition, the system will enter the manual mode.
b.
Make all LOCAL MANUAL/AUTO switches connected in series. When any of the LOCAL
