loop devices are added, they are summarised in the “Summary of loop units”
providing information for total quiescent and maximum consumption in the “Properties for
NMAST loop” dialog box. See Figure 57 below for steps to access the information from
EBLWin under their respective loops.
Figure 57 Access to COM loop units current consumption
The current consumption of FT1020G3 from the power supply and the charging current for
the battery with battery temperature can be displayed via menu H5/A4.
An approximate value of individual COM loop is also displayed via menu H5/A5.

Quiescent and alarm current must be added correctly for each brigade unit e.g. Romtec, Tyco ASE, etc. Separate power supply
and batteries may be required.
181
OWS with higher wattage e.g. 120W or 250W requires separate power supply and battery backup.
