4. Technical description.

4.1. General description.

The buffer power supply has been designed for an uninterrupted supply of fire alarm systems, smoke and
heat control systems, fire protection equipment and fire automatics requiring stabilized voltage of 24 V DC (± 15%).
The PSU is fitted with two independently protected outputs AUX1 and AUX2, which supply voltage of 27,6 V DC
with a total output current:

Continuous operation

Output current Imax a=2 A

Instantaneous operation

Output current Imax b=3 A

In case of power loss, the PSU switches to battery power, providing uninterruptible power supply. The
PSU is enclosed in a metal casing (color: RAL 3001 - red) with battery housing for two 17 Ah/12 V batteries. The
PSU works with maintenance-free lead acid batteries made with AGM technology or gel technology.

4.2. Block diagram.

The PSU has been manufactured based on a high-efficiency system of DC/DC converter. Applied
microprocessor circuit is responsible for the full diagnostics of the PSU parameters and batteries. The figure below
shows a flowchart of the power supply, along with selected functional blocks which are essential for the proper
functioning of the unit.

CAUTION!
Before installation, cut off the voltage in the 230 V power-supply circuit.
To switch power off, use an external switch, in which the distance between the contacts of
all poles in the disconnection state is not less than 3mm

5. Installation.

5.1. Requirements.

The PSU is to be mounted by a qualified installer, holding relevant permits and licenses (applicable and
required for a given country) for ~230 V in and low-voltage installations.

As the power supply is designed for a continuous operation and is not equipped with a power­switch, therefore, an appropriate overload protection in the power supply circuit should be provided. Moreover, the
user should be informed how to disconnect the power supply unit from the mains supply (usually by assigning an
appropriate fuse in the fuse box). The electrical system shall be made in accordance with applicable standards and
regulations. The power supply should operate in a vertical position in order to provide free and convectional
air flow through ventilating holes of the casing. If necessary, it is possible to permanently disconnect the battery
from the power supply systems by removing the F

As the PSU performs a periodic battery test, measuring the resistance of connections, special attention
should be paid to the proper installation of the cables. Installation cables should be firmly connected to the battery
side terminals and to the power supply connector.
The side walls of the housing include the embossings, which should be used to carry out installation cables. Use a
blunt instrument to make an opening for cable gland from the outside of the housing. Then, carefully mount the
cable gland, protecting the PSU from water penetration, in the opening.

fuse.

Fig. 5. The method of forming an opening for cable gland.

The PSU is fitted with PG9 and PG11 cable glands. Gland size should be chosen depending on the cross­section of the cable. Single cable gland can be used for only one wire.

Fig. 6. Recommended types and sections of installation cables PG9 and PG11 for cable glands.
The PSU is protected against access to the configuration menu through two-level passwords. If

the default settings should be changed, unlock access by entering the service password – see Table 5
and section 7.1.

It is required to install an installation switch with a nominal current of min. 3 A in the power supply circuits

outside the power supply unit.

1. Mount the PSU in a selected location with use of special metal expansion bolts. Do not use PVC dowels.

2. Connect the power cables (~230 V) to L-N terminals of the PSU. The cable length inside the housing
should not exceed 10 cm. Connect the ground wire to the terminal marked with grounding symbol. Use a
three-core cable (with a yellow and green protection wire) to make the connection.

The shock protection circuit shall be done with a particular care: the yellow and green wire coat of
the power cable should be connected to the terminal marked with the grounding symbol on the
PSU enclosure. Operation of the PSU without the properly made and fully operational shock protection
circuit is UNACCEPTABLE! It can cause damage to the equipment or an electric shock.

3. Connect the receivers’ cables to the AUX1 and AUX2 output terminals on the PSU board.

4. If needed, connect the cables from the devices to the technical inputs and outputs:

- ALARM; technical output of collective failure of the PSU

- EPS FLT; technical output of AC power loss indication

- PSU FLT; technical output of PSU failure.

- APS FLT; technical output of the battery failure.

- EXTi; input of collective failure

5. Install the batteries in a designated area of the enclosure (see Fig. 4). Connect the batteries with the PSU
paying special attention to the correct polarity. Batteries must be connected in series using the special
cable (included).

6. Switch on the ~230 V supply. The corresponding LEDs on the power supply PCB should be ON: green AC
and green AUX1 and AUX2. Green LB LED should light up while charging.

7. Check the current consumption of the receivers, taking into account the battery charging current, so as not
to exceed the total current efficiency of the PSU (see section 4.1).

8. Once the tests are completed, close the enclosure.
