1. The FACP can only support 5 devices w/LED’s on. This current draw has been added to the panels alarm current.
2. If using 24 VDC aux power only. No standby or alarm current for battery calculation if using 24 VAC, 120 VAC or 240 VAC.
3. 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 6.0A total current that can be
drawn from the panel.
4. Use next size battery with capacity greater than required.
