2. Technical description.
2.1. General description of the power supply system of the DSO.
The DSOP24V power supply system is designed for uninterrupted supply of Voice Alarm Systems requiring
stabilized voltage of 24V DC (-15%, +20%). The system can be equipped with a 320 - 1000W power supply unit
with independently protected outputs for 5 or 9 audio amplifiers (each with 1000W power), 6 routers, and 1
controller.
The power supply is designed to supply 24V DC power to the controller and routers while the power supply
is powered directly from a 230V AC mains supply. In the case of mains power loss, all devices immediately switch
to a 24V DC battery backup. The entire DSO system with batteries is configured to provide the alarm and
supervision within the time required by the regulations when using backup power.
The DSO power supply system is housed in a RACK 19" enclosure with a space for additional equipment
and appropriate battery packs. The power supply unit uses maintenance free Sealed Lead-Acid (SLA) batteries
(AGM or gel batteries, included)
The system allows connection of 1 or 2 strings (circuits) of batteries, each with up to 230Ah, which allows for a total
capacity of 460Ah.
Power supply from the power grid can be supplied to the cabinet in the form of 1-phase or 3-phase
connection, which depends on the total power consumed by the DSOdevices.
The power supply unit is equipped with a system for measuring the resistance of batteries. Battery
monitoring is performed independently for each installed battery string.
The power supply is equipped with an additional Ethernet module with a 10Base-T/100Base-TX interface
to connect to the Internet. Such a configuration enables the remote monitoring of the Voice Alarm System over the
Internet from anywhere. The Ethernet module has a built-in powerful web server that allows remote monitoring of
the current status of the power supply in the browser of any PC computer. In addition, an email alert allows sending
information about the system status in case of certain events.
The CONFI-DSO program is designed for the proper and fast configuration of the DSO cabinet; based on
the implemented design parameters, the program selects a complete power supply system taking into account the
required backup time.
2.2. Electrical scheme.
Figure 1 shows an exemplary wiring diagram inside a DSO cabinet for a 3-phase 230V/400V AC
connection.

3. The design of the Voice Alarm System.
The design and all components of the DSO are based on the RACK 19" cabinet (Protection Class: IP30),
containing all components of the system. Depending on the system and the number of devices, the height of the
cabinet is adjusted individually. The available dimensions are: 24U(600x600), 42U(600x600, 600x800), 45U
(600x600, 600x800), and 50U (600x800).
For easier installation of equipment, the interior space is fitted with individual mounting shelves for each
unit. If a call station (firefighter's microphone) is to be mounted in the rack, a dedicated pull out shelf will be added
to facilitate the use of the microphone.
The equipment installed inside the cabinet can be accessed via the glass front doors, removable side
walls, and rear doors. In addition, the use of two types of locks, separate for the front and rear doors, restricts
unauthorized access. The cabinet can be mounted on a metal base with a height of 100 mm or wheels allowing it
to move freely.
The DSO power supply system includes full wiring (of appropriate length and cross-section of wires) which
can be adjusted individually for each configuration.

4. Components of the DSO cabinet.
The equipment of each DSO cabinet includes the elements necessary for the proper operation of the
system. These components, depending on their intended use, protect the electrical system against overvoltage or
short circuit, supply power to the receivers, and ensure proper signaling or cooling of the installed equipment in the
RACK cabinet.
If the device comes in several models, they are selected automatically by the CONFI-DSO program
supporting the DSO configuration.
4.1. The LZxxxx safety strip.
Safety strip is fitted with circuit breakers, surge arresters, and a dummy connector.
The main overcurrent circuit breaker disconnects the 230V/400V mains from all system devices. In
addition, the power supply circuit is fitted with an overcurrent circuit breaker allowing its disconnection, e.g. for
maintenance purposes, without disconnecting other devices of the DSO. In addition to the main switch, it is fitted
with "type 3" surge arresters compliant with the EN 61643-11 standard.
The dummy connector includes overcurrent circuit breaker which can be switched on regardless of the
status of the main switch.

4.3. The PSG3LA panel for optical and acoustic indication.
The optional panel for optical and acoustic indication compliant with the PN-EN54-16 standard indicates
the status of the entire DSO system. It is equipped with three LEDs, a sounder, and a reset button of acoustic
indication.
The panel can indicate three different operating states
CONTROL –Normal state, indicating the presence of mains power.
ACOUSTIC INDICATION –Fire alarm status, acoustic indication ON
FAILURE –Fire alarm status, acoustic indication ON
The indication panel is fitted with two alarm signal inputs:
- ACOUSTIC INDICATION
- FAILURE
Inputs should be connected to the control panel or other signaling device. For proper signalization, the
terminals must be normally (without failure) opened; in the case of failure, they must be closed. A voice alarm
signal or failure indication triggers the appropriate optical and acoustic indication. The button on the front panel
allows muting the acoustic signal, while the optical signal remains unchanged. Once the failure is cleared, the
optical and acoustic indication will automatically be stopped and the green indicator will light up to indicate that the
system is operating properly.

5. The PS24DSOxxxx power supply unit.
The PS24DSOxxxx power supply is the main component of the DSO power supply system supplying power
to the controller and routers of the DSO system during normal operation (mains supply operation) and performs
advanced battery charger functions.
Due to its modularity, the power supply can be configured in one of several possible variants, differing in
power, the number of outputs for audio amplifiers, and the number of battery strings. Depending on the design
requirements the power supply can have a power of 320 - 1000W and work with batteries with a capacity of up to
460Ah. In addition, each power supply unit is equipped with an additional Ethernet module with a 10Base-
T/100Base-TX interface to connect to the Internet. Such a configuration enables the remote monitoring of the Voice
Alarm System over the Internet from anywhere.
Choosing the right power supply configuration taking into account all the requirements is done
automatically using the "CONFI-DSO" support program.
5.1. Block diagram.
The power supply unit is based on the high performance AC / DC inverter with an integrated power factor
correction PFC. The used microprocessor system is responsible for the complete diagnostics of parameters of the

The battery current indicator displays the measured current drawn from the battery by the receivers during
battery-assisted operation. During normal operation, the "Io" parameter is not shown on the display.
The resolution of voltage measurement is 0.1V and should be treated with caution. If a greater accuracy is
required, use a multimeter.

5.4.3. The battery circuit resistance indicator „rA1”, „rA2”
The battery circuit resistance indicator shows the measured increase in the resistance in the first "rA1" and
the second "rA2" circuit of batteries connected to the power supply. The resistance is influenced by many factors.
- The quality of the batteries
- The quality of battery cables and connections
- The type of FBAT fuses
If the resistance increase exceeds 60 mΩ, the power supply will report a failure.
The measurement result is displayed with a resolution of 1 mΩ.
5.4.4. The battery temperature indicator „t°C”
The battery temperature indicator displays the measured temperature of the batteries connected to the
power supply unit. The temperature measurement is used by the automation system of the power supply to
compensate the charging voltage.
The measurement result is displayed with a resolution of 1°C.
5.4.5. Failure history “FLh”
The power supply stores the last 30 failures in the non-volatile memory, allowing for a later review.
Use the „<” or „>” buttons in order to display the FLh parameter and confirm by pressing the "OK" button to browse
the failure history. The failure number and its code will be displayed. Pressing the "OK" button again will display the
next failure in the memory.
The event log of the new power supply stores events that occurred during the performance tests at the
production stage.
- Use the „<” or „>” buttons in order to display the "FLh" parameter
- Press „OK”
- The number 1, indicating the failure number in the memory, will be displayed
Then, after 1s., the next error code will be automatically displayed
- Press „OK”
- The number 2, indicating the failure number, will be displayed
Then, after 1s., the next error code will be automatically displayed
- If there are more failures in the memory, press the "OK" button to display the next codes
- The „- - -„ parameter on the display indicates the end of the failure list

5.4.6. The current failures „FLc”
In the event of abnormal electrical parameters during operation, the power supply will indicate a failure by
illuminating the corresponding LED on the panel and activating the acoustic indication (if not disabled).
The power supply unit can simultaneously signal several failures at the same time. In such a case, all failure
codes and their priority can be viewed in the FLc menu. While in the menu, each time you press the "OK" button on
the panel, the next error code that caused the failure is displayed. If several failures occur simultaneously, pressing
the "OK" button again will display the next code. The order of failure display is arranged according to priority. The
failures that are displayed first are of the highest priority.
The section 5.4.7 summarizes all failure codes that may appear during the power supply operation. The
individual codes are accompanied by appropriate optical signaling on the panel, acoustic signaling and the
activation of a dedicated technical output.
- Use the „<” or „>” buttons in order to display the "FLc" parameter
- Press „OK”
- The number 1, indicating the failure number (highest priority) in the memory,
will be displayed
Then, after 1s., the error code will be automatically displayed
- Press „OK”
- The number 2, indicating the failure number in the memory, will be displayed
Then, after 1s., the next error code will be automatically displayed
- If there are more failures in the memory, press the "OK" button to display the next codes
- The "- -" parameter on the display indicates the end of the failure list
