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 If using 24 VDC aux power only. No standby or alarm current is needed for battery calculation if using 24 VAC, 120 VAC, or 240 VAC.
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 using door holders, you do not 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 1.0A total current that can be drawn from
the panel.
6 Use next size battery with capacity greater than required.
