Table 4.3 is used for calculating alarm current draw. Calculate the current and enter the total (in
amperes) in the bottom row. When finished, copy the totals from this table to Table 4.4.
Table Footnotes:
1. Include XPIQ-AA25/XPIQ-AA2270 backup amplifier when used as an external backup to XPIQs that have their
own batteries. These applications are shown in Figure 2.15 on page 40 and Figure 2.17 on page 42.
2. Other devices include devices separate from the XPIQ but backed up by the same battery: for example, APS-6R
used for NAC connected to the same battery as the XPIQ-PS(E).
