Current consumption

The different loop units have different current consumption. Note that
some units have much higher current consumption in "active state"
than in normal state. The tables below can be used:
 To get a total current consumption overview.
 To check the current consumption on the COM loop in relation
to the cable lengths, etc. See also drawing 128-11 and chapter
"COM loop cable length", page 131.
 To check if the battery capacity is enough.
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 rated voltage is 21
See also chapter "Power supply", page 137.
132
There will, however, be voltage in the system down to a battery voltage
of approx. 15 V when it will be switched off in order not to damage the
battery.
133
Control unit electronics only, i.e. the COM loop units' current
consumption and other connected external equipment's current consumption
are not included.
134
Add 3.5 mA (quiescent) and 12 mA (activated) respectively, for each
zone line input used.
135
Add 2.5 mA (quiescent) and 30 mA (activated) respectively, for each
zone line input used.
136
Add 4.3 mA (quiescent) and 30 mA (activated) respectively, for each
zone line input used.
137
Add 7.8 mA (quiescent) and 30 mA (activated) respectively, for each
zone line input used.
