loads at the ends of the circuit. The isolation diodes in the diagrams are used for the short or open circuit
fault detection voltage, but they will not affect the output of driving signals. The selection of isolation
diodes should depend on the load current value. For example, IN5401 isolation diodes should be used
for the driving circuits of the electromagnetic valves (load current: 1~3A).
4.3.2 Description of the output terminals on the master control board
Fig. 4.1 Output Terminals on the Master Control Board
Terminal description:
1.
Terminal 1 on the master control board:
It is for +24V DC power output.(
To connect the
terminal MANUAL FIRE ALARM button 2
)
1)
The +24V power supply necessary to the input terminals of the system is led out from terminal 1.
2)
It can be connected to external devices as a +24V power supply .
2.
Terminal 2 on the master control board: I
t is for the output of electromagnetic valve driving
signals and for the +24V active output.
1)
In any of the following three circumstances, the system will start the electromagnetic valves.
No.
State description
Remarks
1
The system is in the auto mode, the detector has detected a
compound fire alarm and the set delay time is reached.
2
The EMERGENCY RELEASE button on the panel is pressed and
the set delay time is reached.
3
The EXTERNAL MANUAL RELEASE button is pressed and the set
delay time is reached.
2)
Electromagnetic valves are inductive loads, it is therefore necessary to select between the two
connection modes of category 2. Select connection mode A or B according to the judgment on
whether the output circuit has a short or open circuit fault detection function.
When the output circuit needs no short or open circuit fault detection function, select
connection mode A and set the jumper JP7 on the master control board to the ON position.
See Table 3.1.2.
When the output circuit needs a short or open circuit fault detection function, select connection
mode B and set the jumper JP7 on the master control board to the OFF position.
3)
When the circuit suffers a fault, the outputs driven by the electromagnetic valves due to a compound
fire alarm will be forbidden even if the compound fire alarm is detected by the detectors. The
EMERGENCY RELEASE button can still work at this time.
3.
Terminal 3 on the master control board:
It is for the output of release indication signals and for
the +24V active output.
1)
The specific connection mode should be selected according to the load characteristics and the
judgment on whether the output circuit has a short or open circuit fault detection function.
When the connection mode with a short or open circuit fault detection function is selected, the
jumper JP1 on the master control board should be set to the OFF position.
When connection mode without a short or open circuit fault detection function is selected, the
jumper JP1 on the master control board should be set to the ON position. See Table 3.1.2.
When the said fault is occurring, the system will report an output fault (the output fault indicator
on the display panel will be lit).
2)
The maximum output current is 1A.
3)
In case of an input of an external pressure feedback signal or an operation of the electromagnetic
valves, terminal 3 will output a +24V voltage.
4.
Terminal 4 on the master control board: I
t is used as a passive output terminal of fault output.
The jumper JP10 on the master control board is off and terminals 4 and 5 form normally open
passive dry contacts as the passive output signals of fault output. The maximum output current is
1A.
5.
Terminal 5 on the master control board:
It is for the output of faults.
1)
The jumper JP10 on the master control board is off and terminals 4 and 5 form normally open
passive dry contacts.
2)
The jumper JP10 on the master control board has a short circuit and terminal 5 is a +24V active
output terminal for faults.
3)
The maximum output current is 1A.
4)
When it is set as +24V active output terminal, the connection mode should be selected according to
the load characteristics and the judgment on whether the output circuit has a short or open circuit
fault detection function.
When the connection mode with a short or open circuit fault detection function is selected, the
jumper JP4 on the master control board should be set to the OFF position. See Table 3.1.2.
When the connection mode without a short or open circuit fault detection function is selected,
the jumper JP4 should be set to the ON position.
