to the RED ALARM and YELLOW ALARM relay contacts on the CIP.A system
condition that triggers the red or yellow alarm L ED on the craft interface
also activates the corresponding alarm relay contact.
The terminal blocks that plug intothe alarm relay contacts are supplied
with the router. They accept wire of any gauge between 24-AWG and
12-AWG (0.20 and 3.33 mm2), which is not provided. Use the gauge of wire
appropriate for the external deviceyou are connecting.
To replace the wiresconnecting to an alarm-reporting device, follow
this procedure (see Figure 66:
1. Disconnect the existing wire at the external d evice.
2. Prepare the requiredlength of replacement wire with gauge between 24-AWG
and 12-AWG(0.20 and 3.33 m m2).
