12 5895XL Manual — P/N 151142-L8:M 2/15/2022
Before You Begin Installing Earth Fault Resistance
2.4 Earth Fault Resistance
Table 2.2 lists the earth fault resistance detection, in ohms, for each applicable terminal on the FACP.
2.5 Calculating Current Draw and Standby Battery
This section contains instructions and tables for calculating current draws and standby battery needs.
2.5.1 Worksheet Requirements
The following steps must be taken when determining 5895XL current draw and standby battery requirements.
Filling in the Current Draw Worksheet, Table 2.4 or Table 2.5
1. For the 5895XL, the worst case current draw is listed for the panel, addressable devices, and SLC expanders. Fill in the number of
addressable devices and expanders that will be used in the system and compute the current draw requirements for alarm and standby.
2. Add up the current draw for all auxiliary devices and record in the table at Line B.
3. Add up all notification appliance loads and record in the table at Line C.
4. For notification appliances and auxiliary devices not mentioned in the manual, refer to the device manual for the current ratings.
5. Make sure that the total alarm current calculated, including current for the panel itself, does not exceed 6.0 A. This is the maximum
alarm current allowable.
6. Complete the remaining instructions in the table for determining battery size requirements.
