Router Hardware Description
Hardware Features
Alarm Port
See
for the alarm port location.
Attach the alarm port to an alarm system to monitor and trigger external alarm events. The router supports two alarm
inputs and two alarm outputs.
The alarm-trigger setting determines when an alarm is sent to the attached alarm system.
The alarm port has a rating of 30V DC, 1A.
Input Alarm Trigger Settings
Open
—The
open
setting indicates that the normal router operating condition has an electrical current passing
through the alarm circuits (DRY contact closed). If this electrical current is no longer detected (DRY contact open),
an alarm is generated.
Closed
—The
closed
setting indicates that the normal router operating condition is that no electrical current is
passing through the alarm circuits (DRY contact open). If an electrical current is detected (DRY contact closed), an
alarm is generated.
Output Alarm Trigger Settings
Normally Open (NO)
—This setting depends on the pinout of the cable that is connected to the alarm port. See
Connector and Cable Specifications, page 95
.
Normally Closed (NC)
—This setting depends on the pinout of the cable that is connected to the alarm port. See
Connector and Cable Specifications, page 95
.
If interfaces fail or other non-fatal errors occur, the alarm port does not respond. Continue to use SNMP to manage these
types of errors.
Note:
Due to the RJ-45 pin spacing, the alarm port does not support AC signaling.
