3.4.16.4 Managing Dry-contact Input Alarms
Dry-contact input alarms are external devices that are connected to the 4Motion
unit, and notify the system when there is a change in external conditions. When
the system receives this notification, an SNMP trap is sent to the EMS. For
example, a device such as a temperature sensor that is connected to the 4Motion
unit, and configured to function as a dry-contact input alarm, can raise an alarm
to the system when there is a sudden change in the room temperature. The
system then sends an SNMP trap to the EMS, notifying the administrator of the
change indicated by the external device.
Dry contact input 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:
