3.7.5 Connecting ICM-4RK and ICE-4 Modules
The total current available for any group of Notification Appliance Circuits (NACs), other than the
four NACs on the control panel, cannot exceed the following:
• 6.0 A when powered from the APS-6R
• 1.25 A when powered from a NFS-640 DC power output terminal
Shown below are the wire connectors on the bottom of the ICM-4RK and the ICE-4 modules.

Power Supply Connections
The figure below illustrates typical connections from main power supply.
Figure 24 Main Power Supply Connection
Multiple Power Supplies
Cut JP1 and JP2 on ICM-4RK when supplying 24V power from two separate sources to the
ICM-4RK. ICM-4RK circuits 1-2 will receive their power from J5; ICM-4RK circuits 3-4 will
receive their power from J6.
Cut JP1 and JP2 on ICE-4 when supplying power from separate sources to expander circuits 5-8.
ICM-4RK circuits 5-6 will receive power from J5 on the ICE-4 and ICM-4RK circuits 7-8 will
receive power from J6 on the ICE-4.
See Figure 25 for jumper locations.
