Planning Instructions Fire alarm system EBL512 G3, United version 2.7.x
In case of charger out of work the following fault message will
be shown:
FAULT: Charger control unit xx
In order to not damage the batteries, the voltage output will be
switched off at approx. 20.8 V. This only happens in case of
no main power source (230 V AC), i.e. when the backup
batteries are used as power source.
If the battery voltage is below 10 V (5 V per battery), the
battery charging will be turned off.

In case of no mains and after a time delay of 1-300 minutes
(programmable in Win512 version 2.7.x but max. 30 min.
according to the EN54-2 standard), the following fault
message will be shown:
FAULT: Mains, control unit xx
Current consumption calculations
For each control unit, in order to get a current consumption overview
so that the rectifier will not be overloaded and to check / calculate the
required battery capacity, the total EBL512 G3 current consumption
(excl. battery charging current) have to be calculated. NOTE! There
is no battery charging during fire alarm.
Use the values in chapter "Current consumption", page 148, to
calculate the following current consumptions:
I
CN
= current consumption for the control unit
state.

RN
= current consumption for all other equipment
