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.
The buffer power supply is designed in accordance with the requirements of the (I&HAS) EN50131-6:2017
grade 1,2, II environmental class and EN60839-11-2:2015+AC:2015, I environmental 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%).

In case of power failure, a battery back-up is activated immediately.
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:
I=QAKU/12 - IZ
where:
QAKU –minimum battery capacity [Ah]
Iz –PSU current consumption (including optional modules) [A] (Table 3)
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. Connect ground wire to clip marked by earth symbol .
Use a three-core cable (with a yellow and green protection wire to make connection). Wires should be
deisolated to a length of 7mm.
The shock protection circuit shall be performed with a particular care, i.e. the yellow and
green wire coat of the power cable shall stick to one side of the ‘ ’ terminal - in the PSU
enclosure. Operation of the PSU without a properly made and fully operational shock
protection circuit is UNACCEPTABLE! It can cause a device failure or an electric shock.

Green LED AC:
on –PSU is supplied with 230 V
off –no 230 V power, battery-assisted operation
Green LED DC:
on –presence of DC voltage in the output of the PSU
off –no voltage in the output of the PSU
Red LED APS:
off –no failure
on –indicates battery failure status
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.4):
a) b)
.
Fig. 4 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. Optionally, you can install additional
PKAZ168 signal module (chapter 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 5), EPS technical output after time 30s
-battery disconnection: optical indication, APS technical output –after a battery test have been
3. Operating status indication.
The power supply unit features LED and acoustic status indication
3.1 Optical indication.
Moreover, PSU is equipped with LED indicating presence of voltage at PSU output, located on PCB of PSU
module. Moreover, signalling can be extended with optional PKAZ168 module:
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 5 minutes - after each battery test

CAUTION! In figure set of contacts shows a potential-free status of relay, which corresponds to
power supply failure.
3.3 Standby 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)
3.4Battery charging time.
The PSU has a battery circuit charged with direct current. The current selection is done with use of the IBAT
jumpers. The table below shows how long does it take to charge a (fully discharged) battery up to min. 80% of its nominal
capacity.

3.5Running PSU on battery backup.
Power supply allows you to run on battery backup when necessary. To do this, press the START button on PCB.
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. In the case of a fuse replacement,
use a replacement of the same parameters.

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.
CAUTION! The power supply unit is adapted for cooperation with the sealed lead-acid batteries (SLA). After the operation period they must
not be thrown but recycled according to the applicable law.
