Current Draw Worksheet
For *each 5895XL in the installation, use this worksheet to determine current requirements
during alarm/battery standby operation. (Copy this page if additional space is required.)
*
Use a separate worksheet for each 5895XL.
**
If you are 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 6.0 A total current that can be drawn from the panel.
***
Use next size battery with capacity greater than required.
