Alarm Out cable connector

The alarm subconnector can be used to connect the router to an external site alarm maintenance system. Any
critical, major, and minor alarms generated by the router also energize alarm relays on the alarm card and
activate the external site alarm. The alarm relay contacts on the RSP/RP card consist of standard common,
normally open, and normally closed relay contacts that are wired to the Alarm Out connector pins.
Table 8: Alarm Connector Pinout , on page 51
lists the pin-to-signal correspondence between the connector
pins and the alarm relay contacts. Because alarm contact cables are entirely dependent on installation site
circumstances, alarm connector cables are not available from Cisco. For information about alarm connector
wiring requirements and the pinouts for the alarm connector interface, see
.
Only safety extra-low voltage (SELV) circuits can be connected to the Alarm Out connector. Maximum rating
for the alarm circuit is 100 mA, 50 V.
Caution
To comply with the intra-building lightning surge requirements of GR-1089-CORE, Issue II, Revision 01,
February 1999, you must use a shielded cable when connecting to the external alarm port on the RSP/RP card.
The shielded cable is terminated by shielded connectors on both ends, with the cable shield material tied to
both connectors.
