Prerequisites for Installation Calculating Current Draw and Standby Battery
3.5.4 Current Draw Worksheet for SD SLC Devices
Use Table 3.4 to determine current requirements during the alarm/battery standby operation when the SD SLC devices are installed. You can
install up to 127 SD devices per panel, in any combination.
IPDACT-2 IP Communicator Standby: 93 mA mA
Alarm: 136 mA mA
IPDACT-2UD IP Communicator Standby: 98 mA mA
Alarm: 155 mA mA
CELL-MOD/CELL-CAB-SK Standby: 55 mA mA
Alarm: 100 mA mA

1 The FACP can only support 5 devices with LEDs on. The current draw has been added to the panels alarm current.
2 Total does not include isolator devices or accessory bases.
3 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.
4 Maximum SBUS address capacity is determined by the amount of SBUS bandwidth consumed by each SBUS module. Refer to
Section 4.6.2 for SBUS limitations.
5 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.
6 Use next size battery with capacity greater than required.
