Total Standby Current = 0.1590 + C2 + C4 + 0.0017 (if used)
Total Alarm Current = 0.1864 + C1 + C3 + C5 + 0.0158 (if used)
Where
C1 = NAC1 current + NAC2 current, should be less or equal to 2.5 A.
C2 = ∑quantity of each type of detector x standby current/each
C3 = ∑quantity of each type of detector x alarm current/each
C4 = External device current draw through Aux1 and Aux2 in standby stage, either one of
Aux1 and Aux2 should be less than or equal to 0.75 A.
C5 = External device current draw through Aux1 and Aux2 in alarm stage, either one of Aux1
and Aux2 should be less than or equal to 0.75 A.
