32 Installation—Installing the FC-2000
Figure 23: Field Wiring the CPU-2000
Notes:
1. Indicating appliance circuits, remote station trouble output, and the
remote station alarm output are power limited and may be connected
to limited-energy cable.
2. Wire indicating appliances according to their instructions.
3. Terminal blocks will accept 12 to 22 AWG wire.
4. Size indicating appliance circuit wire for a maximum drop of 2.0 volts
DC.
5. See the Device Compatibility document in the Fire Management
Accessories Manual (FAN 445) for compatible indicating appliances.
