Planning Instructions Fire alarm system EBL512 G3, V1.1.x
equipment requiring 24 V DC with battery backup, e.g. the
3364 unit (see page 47). It also has a "/Mains OK" output
(normally low), intended to be connected to the corresponding
input on the 3364 unit.
A light grey metal housing (HxWxD, 288 x 400 x 95 mm).
There is space for two maintenance-free sealed Lead-Acid
backup batteries, 2 x 12 V, 7.5 Ah as the second power source.
Batteries with higher capacity (up to 65 Ah) have to be placed
outside the housing. There are cable inlets on the top, bottom
and back sides of the housing. Two cable glands are supplied.
The unit has one 24 V DC
equipment with up to 2.1 A or 0.85 A continuous current
consumption, at the same time as battery charging is active.
In case of an activated fire alarm in the system, the continuous
current consumption can be up to 4 A.
It has a number of security functions, e.g. against to high
current output and to low battery voltage etc.
information, see the Technical Description and the Product
Leaflet. See also drawings 512 G3 – 31 and – 38.
The COM loop address is set with the Address setting tool
(3314). The unit has an address label on which the
programmed technical address can be written.
The Address setting tool (3314) is also used for the mode
setting:
NORMAL mode: Used for 3366 in system EBL512 G3.
2330 mode: Not used in system EBL512 G3.
2312 mode: Not used in system EBL512 G3.

"Press to acknowledge false alarm". One AAFC per AAFC
zone and up to 50 AAFC:s zones can be used. The COM loop
address is set with the Address setting tool (3314). See also

The rated output voltage for the main power source (rectifier) is 24 V ±
1%. Max. ripple 500 mVp-p. The rated output voltage for the second power
source (the backup battery) is 18 – 28 V DC. NOTE! The voltage will,
however, decrease to approx. 15 V when the output will be switched off in
order not to damage the battery.

A current consumption of 0.85-2.2 A allows only the "low current
charging mode", i.e. the battery capacity can be up to 27 Ah.
A current consumption < 0.85 A allows the "high current charging
mode", i.e. the battery capacity can be up to 65 Ah.

The connection order on the line is not dependent of the address.
