11.3 Determining the batteries and power supply
In this chapter the battery capacity and the power supply required for the station
are determined. The battery capacity and the power supply can be determined as
follows:
● With the ↑ outline quantities tool FX2010 (recommended)
● With these instructions
Planning with the ↑ outline quantities tool FX2010 (document
009716)
The outline quantities tool is an Excel spreadsheet (see diagram), which enables
quick and easy planning.
The system limitations are not contained in the
outline quantities tool. They
must be taken from this document.

Planning with the aid of these instructions
1. Calculate the operating current of all consumers in both quiescent condition
and alarm condition.
2. Define the battery capacity.
3. Define the type and number of power supply units. This is determined by the
operating current of all consumers and the charging current for the batteries.
