Honeywell Silent knight 5895XL - Maximum Battery Standby Load; 2: Current Draw Worksheet for SK SLC Devices

5895XL Manual — P/N 151142-L8:M 2/15/2022 13
Calculating Current Draw and Standby Battery Before You Begin Installing
Maximum Battery Standby Load
Table 2.3 shows the maximum battery standby load for the 5895XL based on 24 and 60 hours of standby. The numbers below have a built in
20% derating factor for the battery amp-hour capacity. The standby load calculations of line G in the Current Draw Calculation Worksheet
must be less than the number shown in Table 2.3 for the battery size used and standby hours required.
2.5.2 Current Draw Worksheet for SK SLC Devices
For each 5895XL in the installation, use this worksheet in Table 2.4 to determine current requirements during alarm/battery standby opera-
tion. See individual FACP manual for maximum number of devices.
