Power Supply Calculations Calculating the System Current Draw
Table 7.3 contains columns for calculating current draws. For each column, calculate the current
and enter the total (in amperes) in the bottom row. When finished, copy the totals from Calculation
Column 2 and Calculation Column 3 to Table 7.4 on page 183.

1 If using the Reverse Polarity Alarm output, add 0.005 amps; if using the Reverse Polarity Trouble output, add another
0.005 amps.
2 Refer to the Device Compatibility Document for standby current.
3 Must use compatible listed Power Supervision Relay.
4 Maximum alarm current for each sounder base is 0.035 amps which must be supplied by aux. 24VDC source.
5 Total current draw listed above cannot exceed 2.7 amps.
