The unit has one 24V
to 2.1 A or 0.85 A continuous current consumption, at the same time as battery
charging is in progress.
system, the continuous current consumption can be up to 4 A.
It has a number of battery protection functions, e.g. monitoring high current output
and low battery voltage etc. For more information, see the Technical Description
and the Product Datasheet. See also drawings F737 & F733.
The COM loop address is set with the Address setting tool 3314 / 4414. The unit
has an address label on which the programmed technical address can be written.
The Address setting tool is also used for the mode setting:
NORMAL mode: Used for 3366 in system FT1020G3.
AAM
Brooks Alarm Acknowledgement Module (AAM)
indication LED and a non-latching switch "Press to acknowledge & investigate
alarm".
One AAM per Alarm Acknowledgement Facility Control (AAFC) zone and up to 100
AAFC's zones can be used. The COM loop address is set with the Address setting
tool 3314 / 4414. See also chapter "Alert Annunciation Applications" page 115.
The address setting tool 3314/4414 is used for address and mode settings:
NORMAL mode: Used for AAFC in system FT1020G3 version < V2.2.x
2330 mode: Used for AAFC in system FT1020G3 version ≥ 2.2.x
Note: The new local alarm acknowledgement unit (LAAU) 4445 is developed by
Panasonic, it is equivalent to Brooks Alarm Acknowledgement Module (AAM).
4445
Local Alarm Acknowledgement Unit (LAAU). The LAAU consists of a PCB with an
alarm indication LED and green non-latching switch for acknowledgement of an
alarm. The PCB is mounted on the rear of a white ABS lid. It can be wall mounted
in a 65mm circular mounting box. One LAAU per LAA zone and up to 100 LAA
zones per control panel can be used. The COM loop address is set with the
address setting tool 3314/4414. See also chapter "Alert Annunciation Applications"
page 115.
The address setting tool 3314/4414 is used for address and mode settings:
NORMAL mode: Used for 4445 in system FT1020G3 version ≥ V2.2.x
2330 mode: Used to program Brooks AAM.
Note: The programming in EBLWin and the operation of the Panasonic 4445 are typically
the same as for Brooks AAM but using different terminology i.e.
LAAU = AAM
LAA zone = AAFC zone
The mode setting is also different in software version ≥ V2.2.x

The rated output voltage for the main power supply is 24V
second power source (the backup battery) is 18 – 28V
while the output will be switched off in order to avoid damaging the batteries.

A current consumption of 0.85-2.1 A allows only the "low current charging mode", i.e. the battery capacity can be up to 26
Ah. A current consumption < 0.85 A allows the "high current charging mode", i.e. the battery capacity can be up to 65 Ah.
However, batteries larger than 12AH require different enclosure to suit.
The AAFC function in EBLW in V2.2.0 has been moved from "Add loop unit" menu tree to the "Obsolete loop unit" submenu.
