1. Total does not include isolator devices or accessory bases.
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.
