Maximum Battery Standby Load

Table 3-5 and Table 3-6 show the standby load calculations for the IFP-2100 based on 24 and 90 hours of
standby. The standby load calculations of line D in the Current Draw Calculation Worksheet must be less than
the number shown in Table 3-5 and Table 3-6 for the selected battery size, standby hour and alarm time. The
numbers below have a built in 20% derating factor for the battery amp-hour capacity.

Honeywell Silent Knight does not support the use of batteries smaller than those listed in Table 3-5 and Table 3-6. If you
use a battery too small for the installation, the system could overload the battery resulting in the installation having less
than the required 24 hours standby power. Use Table 3-5 and Table 3-6 to calculate the correct battery amp hour rating
needed for your installation. It is recommended that you replace batteries every five years.
