24 NFS-640 Installation Manual P/N 51332:B2 07/27/2004
Indicating Circuit Expander - ICE-4
An attaching circuit board that expands the ICM-4RK to a total of eight Style Y (Class B) or Style
Z (Class A) NAC’s. Maximum signaling current is 3 A per circuit or 6 A per module, limited by the
power supply. An Auxiliary Power Harness (P/N 71091) is provided.
Control Relay Module - CRM-4RK
Provides four (4) standard dry Form-C relay contacts. Each relay is field-programmable to respond
to a single initiating device circuit, a group of circuits, or all initiating device circuits. Each relay
features manual On/Off control switches and can be disabled or enabled. Contacts rated for 5 A at
120 VAC or 28 VDC (resistive). Note: CRM-4RK is not listed for use with NFS-640 in releasing
applications.
Control Relay Expander - CRE-4
An attaching circuit board that expands the capacity of the Control Relay Module (CRM-4RK) to
eight (8) Form-C alarm relays. May also be used to expand the ICM-4RK to provide four (4) Form-
C control relays. Contacts rated for 5 A at 120 VAC or 28 VDC (resistive).
Auxiliary Relay Module ARM-4
Provides four (4) auxiliary Form-C relays that can be controlled by a CRM-4RK or CRE-4 relay
module. Normally-open contacts rated for 20 A and the normally-closed contacts are rated for 10 A
at 125 VAC and 30 VDC (resistive). An Auxiliary Power Harness (P/N 71092) is provided.
