Current consumption
The different loop units have different current consumption. Note that
some units have much higher current consumption in "active state".
To check the current consumption on the COM loops, cable lengths,
etc. the tables below can be used. See also dwg. 512 G3 - 41 and
chapter "COM loop cable length", page 145. Also, to get a total
current consumption overview and to check if the battery capacity is
enough, the tables below can be used.
The current consumption is normally shown at nominal voltage (24 V
DC), in
Normal state
(quiescent) and in
Alarm state
(active). By
battery back-up (i.e. no mains) the voltage can be 27 – 21 V DC.
See also chapter "Power supply", page 152.

When the printer is active the current consumption is 667 mA
momentarily.
121
Add 0.5 mA per input (zone) for end-of-line capacitor (470 nF) and 3 mA
per input for end-of-line resistor (10K).
122
Add 30 mA per input (zone) activated. (Each input has a 30 mA current
limitation, i.e. also for short-circuit on the line.)
