Installation
3.12.3 Field Wiring an Auxiliary Relay Module
The figure above shows terminal assignments for ARM-4 module control relays K1-K4, which
control non-power-limited circuits. Power-limited and non-power-limited circuit wiring must
remain separated by at least 0.25 inch (6.35 mm) within the cabinet and exit the cabinet though
different knockouts, conduits, or both. Refer to Section 3.16 "UL Power-limited Wiring
Requirements".
The table contains contact ratings for relays K1-K4 on the ARM-4 module:
Resistive Load
125 VAC
30 VDC

3.13 Notification Appliance Circuit Current Limitations

The total current available from any group of Indication Appliance
Circuits cannot exceed 3.0 amps; this is limited to 1.0 amps if
AMPS-24 is the only power source. Figure 3.18 illustrates some of the
typical power supply/ Notification Appliance Circuit configurations.
