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.
2.5.4 Current Draw Worksheet for SD SLC Devices
For each RPS-1000 in the installation, use this worksheet in Table 2.6 to determine current requirements during alarm/battery standby oper-
ation. See individual FACP manual for maximum number of devices.
For each device use this formula:
