3.4.16.5 Managing Dry-contact Output Alarms
Dry-contact output alarms are raised by the system to notify an external device
connected to the 4Motion unit about a change in the system state. The external
monitoring entity may take the appropriate action after receiving the notification
from the 4Motion system.
You can use the CLI to raise an alarm to the external entity that is connected to
the dry contact output pin. After the system returns to its normal state, you can
clear the dry contact output alarm that you had raised.
Dry contact output alarms are connected to the 4Motion system via a 25-pin
micro D-Type ALRM-IN/OUT connector on the NPU front panel. The following
figure depicts the ALRM-IN/OUT connector, and the pin numbers assigned to
each pin:
