J.3.2 APS-6R Calculations
Supply calculations for systems with an APS-6R follow:
• Add 2.5 A for the APS-6R and 1.2 A for the APS-6R to the AC branch circuit
current in Table 44 and Table 45.
• Do not include the load current on NAC 3 and 4 in the 5.0 A limitation in Table 47
and notes.
System alarm current limitations with an APS-6R installed follow:
• TB2, terminal 1 and 2 or J1 = 3.0 A
• TB2, terminal 3 and 4 or J2 = 3.0 A
• TB2, terminals 1, 2, 3 and 4 combined = 6.0 A
