Alarm Port Pinouts

Alarm Port Pinouts

The router has four alarm inputs. The alarm setting is open or closed.

•Open means that the normal condition has current flowing through the contact (referred to as normally closed contact). The alarm is generated when the current stops.

•Closed means that no current flows through the contact (referred to as normally open contact). The alarm is generated when the current flows.

The alarm input is a dry-contact alarm port. You can connect up to four alarm inputs from devices, such as a door, a temperature gauge, or a fire alarm, to the alarm port. You can use the alarm-contactcommand to set the alarm severity to minor, major, or critical. An alarm generates a system message.

Note External DC bias is not required for the alarm port inputs.

Figure B-6shows the RJ-45 connector pinouts used for alarm, and Table B-9lists the connector pinouts and signals.
