Signal Port Pin Function
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.
JK1, JK2
Alarm digital ports The maximum voltage is 60 VDC and the maximum
load current is 500 mA.
l When minor alarms are generated, JK2 is short-
circuited.
l When critical alarms are generated, JK1 is short-
circuited.
l Users can define alarm levels through the BAM
program.
JKM1-
JKM4
