T4000 Alarm Relay Contacts

The CIP has two alarm relay contacts for connecting the router to external alarm devices
(see Figure 15 on page 28). Whenever a system condition triggers either the red or yellow
alarm on the craft interface, the alarm relay contacts are also activated. The alarm relay
contacts are located below the Routing Engine ports. The terminal blocks that plug into
the alarm relay contacts are supplied with the router. They accept wire of any gauge
between 28-AWG and 14-AWG (0.08 and 2.08 mm
gauge of wire appropriate for the external device you are connecting.
