1.1. General description.
Power supply modules are intended for installation in an additional enclosure. In order to
meet the requirements of IDS and AC standards, enclosure must be designed in accordance to
security level with which compliance is established.
Buffer power supply is designed in accordance with the requirements of (I&HAS) EN50131-6:2017,
grade 1, 2 and II environment class and (KD) EN60839-11-2:2015+AC:2015 standard and I environment class.
Power supplies units are intended for an uninterrupted supply of I&HAS and KD devices requiring stabilized voltage
of 12 or 24 V DC (±15%).

Depending on a required protection level of the alarm system in the installation place, the PSU efficiency
and the battery charging current should be set as follows:
Grade 1, 2 - standby time 12h:
The 12h standby output current can be calculated from the formula:
IWY=QAKU/12 - IZ
where:
QAKU –minimum battery capacity [Ah]
Iz–PSU current consumption (including optional modules) [A] (Table 2)
PSU module should be configured properly, depending on application, to work in
burglary and assault signalling systems or access control. For this purpose, appropriate
charging current should be selected (taking into account battery capacity and required
charging time).

2. Installation.
2.1 Requirements.
Power supply modules are intended for installation in an additional enclosure. In order to
meet the requirements of IDS and AC standards, enclosure must be designed in accordance to
security level with which compliance is established.
Buffer power supply is designed to be installed only by qualified installer with necessary permits and
authorisations (required in installation country) to connect (interfere) with the 230 V mains supply. The PSU shall work in
a vertical position that guarantees sufficient convectional air-flow through ventilating holes of the enclosure. The device
be mounted in a metal enclosure (cabinet) in a vertical position so as to ensure free, convection air flow through the
vents. In order to meet the EU requirements, follow the guidelines on: power supply, enclosures and shielding: -
according to application.
As the PSU is designed for a continuous operation and is not equipped with a power-switch, therefore an
appropriate overload protection shall be guaranteed in the power supply circuit. Moreover, the user shall be informed
about the method of unplugging (usually through assigning an appropriate fuse in the fuse-box). The electrical system
shall follow valid standards and regulations.
2.2 Installation procedure.
CAUTION!
Before installation, make sure that the voltage in the 230 V power-supply circuit is cut off.
To switch off power use an external switch in which the distance between the contacts of all
poles in the disconnection state is not less than 3mm.
It is required to install an installation switch with a nominal current of 6 A in the power supply circuits
outside the power supply unit.
1. Mount the PSU in a selected location and connect the wires.
2. Connect power cables (~230 V) to L-N clips of PSU. Use a two-core cable. Wires should be deisolated to a
length of 7mm.
3. If needed, connect the device cables to the technical outputs:
- EPS; technical output indicating AC power failure
- APS; technical output indicating battery failure
4. Connect equipment to the appropriate output terminals of power supply (positive connector +V, negative
connector -V)
5. Use the IBAT jumper to set the maximum battery charging current, taking into account the battery parameters and
required charging time.
6. Mount the battery in the battery compartment of the enclosure. Connect the batteries with the PSU paying
special attention to the correct polarity and type of connections (Fig. 3):

Fig. 3 Connecting batteries depending on voltage version of power supply:
a) version 12V, b) version 24V.
7. Switch on the 230 V supply. LEDs on the PCB of power supply should light (see section 3.1). After installing and
checking proper working, the enclosure can be closed.
Output voltage of the PSU, without load U = 13,8 (27,6) V DC.
During battery charge, voltage can amount to U = 11 - 13,8 (22 - 27,6) V DC.
8. Run the PSU test: check the LED and acoustic indication (Tab. 7), technical output; through:
- cutting off the 230 V current: LED AC (Fig. 2 level 1), EPS technical output after time 30s
-battery disconnection: optical indication, APS technical output –after a battery test have been (~3min).
Fig. 4. Example of installation
3. Operating status indication.
The power supply unit features LED status indication
3.1 Optical indication.
The power supply is equipped with LEDs located on the cover of the power supply module, indicating the
operating status:

3.2 Technical outputs.
The PSU is equipped with indication outputs:
EPS FLT - technical output indicating 230 V power failure.
The output indicates 230 V power failure. In case of power failure, contacts of relay change over after about
30 seconds.
APS FLT - output indicating battery failure.
The output indicates the PSU failure. In case of failure, contacts of relay change over.
PSU failure can be caused by the following events:
- defective or low battery
- battery fuse failure
- no continuity in the battery circuit
- battery voltage below 11,5 (23) V during battery-assisted operation
A battery failure is detected within a maximum of 3 minutes - after each battery test
The power supply technical outputs are open collector (OC) type, as shown schematically below.
Fig. 5. Electrical diagram of OC outputs.
3.3 Technical outputs relay type
If OC type outputs are not sufficient to control unit, it is possible to use AWZ642 relay module changing technical
outputs of OC type to relay type.
Fig. 6. The diagram of connecting the AWZ642 module.
3.4Standby time.
Battery-assisted operating depends on battery capacity, charging level and load current. To maintain an appropriate
standby time, Required battery capacity can be calculated using following formula:
QAKU=Standby Period*(IWY + Iz)
where:
QAKU –minimum battery capacity [Ah]
IWY –power supplies output current (drawing by the load)
Iz –PSU current consumption (including optional modules) [A] (Table 3)

3.5Battery charging time.
PSU has a battery circuit charged with direct current. Current selection is done with use of the IBAT jumpers.
Table below shows how long does it take to charge a (fully discharged) battery up to min. 80% of its nominal capacity.

3.6Running PSU on battery backup.
Power supply allows you to run on battery backup when necessary. To do this, press the START button on the
cover of the power supply module.
4. Maintenance.
Any and all maintenance operations may be performed following the disconnection of the PSU from the power
supply network. The PSU does not require performing any specific maintenance measures, however, in the case of
significant dust rate, its interior is recommended to be cleaned with compressed air.
WEEE LABEL
Waste electrical and electronic equipment must not be disposed of with normal household waste.
According to European Union WEEE Directive, waste electrical and electronic equipment should
be disposed of separately from normal household waste.
