The polarity for the alarm and Alarm Control Output of the
monitor should be matched.

100mA.
If the power capacity of the alarm is less than 100mA at DC
24V, the alarm can be connected at the terminal of Alarm

If the power capacity of the alarm is more than 100mA at
DC24V, the alarm can not be connected at terminal direct­
ly. In this case, the relay circuit should be used for the
alarm.
