16 5895XL Manual — P/N 151142-L8:M 2/15/2022
Before You Begin Installing Calculating Current Draw and Standby Battery
2.5.3 Current Draw Worksheet for SD SLC Devices
For each 5895XL in the installation, use this worksheet in Table 2.5 to determine current requirements during alarm/battery standby opera-
tion. See individual FACP manual for maximum number of devices.

1 The FACP can only support 5 devices with LEDs on. The current draw has been added to the panels alarm current.
2 The SK-BEAM-T draws a maximum of 500mA from auxiliary power when the test feature is used. This should be considered when
determining auxiliary power capacity but not calculated into current requirements for everyday operation.
3 Maximum SBUS address capacity is determined by the amount of SBUS bandwidth consumed by each SBUS module. Refer to the FACP
manual for SBUS limitations.
4 If there are door holders in the system, there is no need to consider door holder current for alarm/battery standby, because power is
removed during that time. However, during normal operation, door holders draw current and must be included in the 1.8 A total current that
can be drawn from the panel.
5 Use next size battery with capacity greater than required.
