3. Technical description.
3.1 General description.
The buffer power supply is designed in accordance with the requirements of the EN 50131-6
standard, grade 1÷3 and II environmental class. It is intended for an uninterrupted supply of alarm system devices
requiring stabilized voltage of 24VDC (+/-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
Output voltage 0,58A + 1,5A battery charge
** Grade 3 - standby time 30h if the faults of the main power source are reported to the Alarm Receiving
Centre - ARC (in accordance with 9.2 –EN 50131-1 standard).
Output voltage 0,23A + 1,5A battery charge
- standby time 60h if the faults of the main power source are reported to the Alarm Receiving
Centre - ARC (in accordance with 9.2 –EN 50131-1 standard).
Output voltage 0,116A + 1,5A battery charge
*** General use –if the PSU is not mounted in an installation complaint with the EN-50131 standard, the
acceptable current efficiency amounts to:
1. Output voltage 2A + 0,2A battery charge
2. Output voltage 1,6A + 0,6A battery charge
3. Output voltage 1,2A + 1A battery charge
4. Output voltage 0,7A + 1,5A battery charge
Total current of the receivers + battery: 2,2A max.
In case of power decay, a battery back-up is activated immediately. The PSU is housed in a metal
enclosure (color: RAL 9005 - black) with battery space for a 2x7Ah/12V battery. It is fitted with micro switches
indicating unwanted door opening (front panel) and detachment from the mounting surface.
3.2 Block diagram.
The PSU is manufactured based on a high-duty system of DC/DC converter. The microprocessor system is
responsible for full diagnostics of the PSU and battery parameters.

4. Installation.
4.1 Requirements.
The PSU is to be mounted by a qualified installer, holding relevant permits and licenses (applicable and
required for a given country) for 230V/AC in and low-voltage installations.
As the power supply is designed for a continuous operation and is not equipped with a power-
switch, 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.
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 4 and
section 6.1.
4.2 Installation procedure.
CAUTION!
Before installation, cut off the voltage in the 230V power-supply circuit.
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.
1. Mount the PSU in a selected location. It is particularly important to bolt the tamper grip to the mounting surface.
The grip is located in the central part of the enclosure (see fig. 3 [7]) and guarantees indication in case of any
attempts of detaching the device from the mounting surface. Proper installation is one of the requirements of the
EN 50131-6 standard.
Fig. 4. Fixing a tamper grip.
2. Connect the power cables (~230VAC) to L-N terminals of the PSU. Connect the ground wire to the terminal
marked by the earth symbol: PE. Use a three-core cable (with a yellow and green PE protection wire) to make the
connection. Lead the cables to the appropriate terminals through the insulating bushing.
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 - marked with the PE symbol on the PSU
enclosure. Operation of the PSU without the properly made and fully operational shock protection circuit
is UNACCEPTABLE! It can cause a device failure or an electric shock.
3. Connect the receivers’ cables to the +AUX, -AUX connectors of the terminal block on the PSU board.
4. If necessary, connect the device’s leads to the technical inputs and outputs:
- EPS FLT; technical output of AC power loss indication (alarm panel, controller, indicator, etc.)
- PSU FLT; technical output of the PSU failure.
- APS FLT; technical output of the battery failure.
- TAMPER; output indicating enclosure opening or detachment from the assembly surface.

www.pulsar.pl PSBEN2024B/LCD BLACK POWER
10
- EXT IN; input of collective failure.
5. With the IBAT jumper determine the maximum battery charging current, in accordance with the battery
parameters.
6. With the PBAT jumper determine if the discharged battery disconnection system U<20V (+/-5%) shall be on or off.
The battery protection is on when the PBAT jumper is off.
7. Switch on the ~230V AC supply (red AC diode and green AUX diode should be on).
8. Check the output voltage (the PSU voltage without load and without battery should amount to 27,5V ÷ 27,7V,
with a battery or during battery charging process: 22V÷27,6V). If the value of the voltage requires adjustment, it
should be set with use of the VADJ potentiometer, monitoring the voltage at the AUX output of the PSU.
9. Connect the batteries in accordance with the markings: +BAT red to 'plus', -BAT black to 'minus’. The LB diode
should be on during battery charging process.
10. Press the STOP button to activate or deactivate a dynamic battery test. Deactivating the test turns out the PSU
failure indication at the APS FLT output, but it does not affect the protection system against complete battery
discharge.
11. 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.
12. Once the tests are completed, close the PSU cover.

5.5Acoustic indication.
Emergency situations are acoustically indicated. The frequency and the number of signals depend on an
event type (see chapter. 5.4.6). The acoustic indication is off after removing an appropriate jumper (fig. 2, [5]).

5.6 Technical outputs.
The PSU feature indication outputs, with galvanic isolation, which change their state if any of the following
events occur:
EPS FLT - output indicating AC power loss.
The output indicates 230V AC power loss. Under normal status, with the 230V AC power on, the output
is closed. In case of power failure, the PSU will switch the output into the open position after a time lag
determined in the „ Delay time for EPS output” menu (see section. 6.2.4).
APS FLT - output indicating battery failure.
The output indicates a failure in the battery circuit. Under normal status (during correct operation) the
output is close. In case of a failure the PSU will switch the output into the open state. Any failures can be
triggered by the following events:
- a faulty or undercharged battery
- battery voltage below 23V during battery-assisted operation
- battery fuse failure
- no continuity in the battery circuit
PSU FLT - output indicating PSU failure.
The output indicates the PSU failure. Under normal status (during correct operation) the output is close.
In case of a failure the PSU will switch the output into the open state. Any failures can be triggered by the
following events:
- low output voltage Uaux<23,6V
- high output voltage Uaux>29,4V
- high battery voltage Uaku>28V (during battery test)
- polymer fuse PTC activation
- exceeding the PSU nominal current
- failure in the battery charging circuit
- activation of the over voltage protection OVP
- enclosure opening - TAMPER
- internal damage of the PSU
- EXT IN input activation
The technical outputs have been implemented with galvanic isolation between the PSU’s systems and the
attached devices.

5.7 Input of collective failure EXT IN.
The EXT IN (external input) technical input indicating a collective failure is intended for additional, external
devices that generate the failure signal. The voltage at the EXT IN input will save information about an incident in
the internal memory of the power supply and sending the signal about the failure to the PSU FLT output.
The EXT IN technical input has been implemented with galvanic isolation between the PSU’s systems
and the devices attached.
Fig. 16. Electrical diagram of the EXT IN input.
The electrical diagram below shows the way of connecting external devices to the EXT IN input. Outputs
such as: OC (open collector), relay may be used as a source of the signal.
Fig. 17. Examples of connections.
In the option with tamper switches, the VEXT jumper must be on. It polarizes the EXT IN input circuit
therefore is required in such configuration.
The EXT IN input has been adjusted to cooperate with fuse modules that generate a failure signal in case
of a fuse fault in any of output sections (e.g. AWZ535, AWZ536). To guarantee a correct cooperation between the
module and the EXT IN input, the VEXT jumper must be on and the connections are to be made accordingly to the
diagram below.
Fig. 18. Example of a connection with the fuse module: AWZ535 or AWZ536.
