Power Supply Calculations Calculating the System Current Draw
Table 7.3 contains three columns for calculating current draws. For maximum output current avail-
ability per circuit and per panel, refer to Section 1.2, “Specifications”, on page 15. For each col-
umn, 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 119.

Table 7.3 System Current Draw Calculations
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 The current draw shown represents one zone (IDC) on the main circuit board in alarm. One zone consumes
0.040 amps.
3 An ANN-LED is supplied standard with the MS-5UDC and MS-10UDC.
4 Refer to the Device Compatibility Document for standby current.
5 Enter the number of IDCs used minus one.
6 Must use compatible listed Power Supervision Relay.
7 Total current draw listed above cannot exceed 3.25 amps for the MS-5UD-3(E), 3.28 for the MS-10UD-3(E),
7.25 for the MS-5UD-7(C/E), and 7.28 for the MS-10UD-7(C/E).
