Calculating the System Current Draw
Power Supply Calculations
IQ-301 PN 50036:F 10/29/2001
129
Table 47 contains three columns for calculating current draws. For each column,
calculate the current and enter the total (in amps) in the bottom row. When finished,
copy the totals from Calculation Column 2 and Calculation Column 3 to Table 48 on
page 131.
Notes for Table 47:
1. Refer to the Notifier Device Compatibility Document for compatible devices and
their current draws.
2. For non-English language systems, the LCD-80TM (Terminal Mode) standby
current is 0.100 A.
3. Do not enter current for NAC #3 and NAC #4 in Table 47 if powering these circuits
from an AVPS-24 or APS-6R. For more information on the AVPS-24 and
APS-6R, refer to Appendix J.
4. The RTM-8 alarm current is based on all eight alarm relays being activated. The
alarm current can be reduced by 0.019 A for each zone (between zone 1 and
zone 8) that is not used by the system.
5. Enter in Column 2: “number of MMX-2 plus FZM-1” multipled by 0.090
