Pin Function
BAT_WE
Sensor port of
battery temperature
1
l
Pin 1 is for grounding.
l
Pin 2 is for the signal cable.
l
Pin 3 is reserved.
l
Pin 4 is for the +12 V power supply.
The external sensor outputs the 0-5 V voltage signal.
VBTEM2
Sensor port of
battery temperature
2
l
Pin 1 is for the +24 V power supply.
l
Pin 2 is for the temperature signal cable.
The external sensor outputs the 4-20 mA current signal.
WATER
Water sensor port
l
Pin 1 is for the +12 V power supply.
l
Pin 2 is for the signal cable.
l
Pin 3 is for grounding.
l
Pin 4 is reserved.
When the impedance between pin 2 and pin 3 drops to
a certain range, alarms are triggered.
TEM_HU
Sensor port of
temperature and
humidity 1
l
Pin 1 and pin 3 are for the +24 V power supply.
l
Pin 2 is for the temperature signal cable.
l
Pin 4 is for the humidity signal cable.
VTEM2
Sensor port of
temperature and
humidity 2
l
Pin 1 is for the +24 V power supply.
l
Pin 2 is for the temperature signal cable.
The external sensor outputs the 4-20 mA current signal.
JTP1
Sensor port of the
MDF
l
Pin 1 is for the signal cable.
l
Pin 2 is reserved.
SMOKE
Smoke sensor port
l
Pin 1 is for the signal cable.
l
Pin 2 is for the +24 V power supply.
JTM1
Door-status sensor
port
l
Pin 1 is for the signal cable.
l
Pin 2 is for the +24 V power supply.
By default, when pin 1 and pin 2 are connected, the door
is in the normal state; when they are disconnected,
alarms are triggered. If no door-status sensor is used,
connect pin 1 and pin 2 to disable door-status alarms.
