Replace Alar m Relay Wires
To connect the router to external alarm-reporting devices, attach wires
to the
RED ALARM and YELLOW ALARM relay contacts on the CIP. A system
condition that triggers the red or yellow alarm LED on the craft interface
also activates the corresponding alarm relay con tact.
The terminal blocks that plug into the 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 mm
2
), which is not provided. Use the gauge of wire
appropriate for the external device you are connecting.
To replace the wires connecting to an alarm-reporting device, follow
this procedure (see Figure 66:
1. Disconnect the existing wire at the external device.
2. Prepare the required length of replacement wire with gauge between 24-AWG
and 12-AWG (0.20 and 3.33 mm
