2: Current Draw Worksheet For Sk Slc Devices - Honeywell 6820 Manual

Calculating Current Draw and Standby Battery
5. Make sure that the total alarm current you calculated, including current for the panel itself, does not exceed 9.0 A. This is the maximum
alarm current for the 6820 control panel. If the current is above 9.0 A you will need to use a notification power expander(s) such as the
5496 or the 5895XL intelligent power expander, to distribute the power loads so that the 6820 or the power expanders do not exceed
their power ratings. Refer to the current draw worksheets provided with the 5496 or the 5895XL manuals so you do not exceed their
power ratings.
6. Complete the remaining instructions in the appropriate current draw worksheet for determining battery size requirements.
3.5.2 Current Draw Worksheet for SK SLC Devices
Use Table 3.2 to determine current requirements during alarm/battery standby operation when SK SLC devices are installed. You can install
up to 159 SK sensors per loop (1,110 points max per panel) and 159 modules per loop (1,110 points max per panel).
For each device, use this formula:
