3.7.7 Connecting CRM-4RK/CRE-4 Modules
Guidelines for field-wiring the CRM-4RK and the CRE-4:
• Provide Form-C relay contacts (silver alloy) used for medium duty switching or pilot duty.
• Terminals will accept wire sizes from 12 AWG to 18 AWG (3.1 to 0.78 mm
2
).
• Activation of a module or expander relay occurs automatically when an alarm is detected on
a programmed IDC.
• UL contact ratings are 5 A at 125 VAC (resistive) or 30 VDC (resistive) and 2 A at 125 VAC
(inductive).
• For more information, refer to Section 3.6 “UL Power-limited Wiring Requirements”.
• For typical field-wiring connections, refer to Figure 28.
