2. Technical description.
2.1. General description.
The buffer power supply has been designed in accordance with the requirements of the PN-EN 50131-6
standard, grade 1÷3 and II environmental class. It is intended for an uninterrupted supply to alarm system devices
requiring stabilized voltage of 12V/DC (+/-15%).
Depending on a required protection level of the alarm system in the installation place, the PSU efficiency
and the battery charging current ought to be measured as follows:
* Grade 1, 2 - standby time 12h
Output voltage 1,4A + 3A 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 – PN-EN 50131-1).
Output voltage 0,56A + 3A 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 – PN-EN 50131-1).
Output voltage 0,28A + 3A battery charge
*** General use – if the PSU is not mounted within an installation which is PN-EN-50131 compliant, the
acceptable current efficiency amounts to:
1. Output voltage 10A + 0,6A battery charge
2. Output voltage 9,1A + 1,5A battery charge
3. Output voltage 8,4A + 2,2A battery charge
4. Output voltage 7,6A + 3A battery charge
Total current of the receivers + battery: 10,6A max.
In case of power decay, a battery back-up is activated immediately. The PSU is housed in a metal
enclosure (colour: RAL 9005 - black) which can accommodate a 17Ah/12V battery. It features micro switches that
indicate unwanted door opening (faceplate) and detaching fromthe mounting surface.
2.2. Block diagram.
The PSU has been manufactured based on a high-duty system of DC/DC converter. It features a
microprocessor-based operation control, responsible for full diagnostics of the PSU and battery
parameters.

3.2 Overview of current failures.
If any incorrect electrical parameters occur, the PSU will signal the failure by illuminating an appropriate LED
on the panel or by activating an acoustic indication (provided it has not been switched off). After pressing the ‘OK’
button, the panel display will show a code of the fault that trigger the failure. If more than one failure occurs
simultaneously, another pressing the ‘OK’ button will display the next failure code.
In chapter 9 all possible failure codes that can appear during the PSU’s operation have been shown. Each
code is accompanied by an appropriate LED indication on the panel, acoustic indication and switching of a
dedicated technical output.
3.3 Overview of failure memo.
The device remembers 30 last failures in non-volatile memory which enables a subsequent overview.
Entering the failure memo overview mode:
With the “<”, “>” buttons choose the FLt position and approve by pressing “OK”. The number of the failure will be
displayed, then its code. Pressing “OK” again will display the next failure in the memory.
3.4 Acoustic indication.
Emergency situations are acoustically indicated. The frequency and the number of signals depend on an event
type (see chapter 9). The acoustic indication is off after removing an appropriate jumper (fig. 2, [5]).
Table 4. Acoustic indication.
No. Description Event
1 1 signal per 10s, battery-assisted operation No 230V AC supply
2 1 signal per 10s, mains operation Battery fault, undercharged battery
3 2 signals per 10s, battery-assisted operation Low level of battery charge
4 Fast signals, battery-assisted operation The PSU will be disconnected due to the battery
discharge
5 Continuous indication PSU failure [see chapter 9]
6 1 signal Breaking the battery test
7 2 signals Activation of the battery test
3.5 Technical outputs.
The PSU feature indication outputs, with galvanic isolation, which change state if any of the following event
occur:
•EPS FLT – output indicating AC power loss.
The output indicates AC power loss. Under normal status – with the 230V AC supply, the output is
close. In case of a power failure the PSU will switch the output into the open state after a period of time
determined by the T
AC
(J1, J2) jumpers.
J1= , J2= time lag T= 5s
J1= , J2= time lag T= 140s
J1= , J2= time lag T= 17m
J1= , J2= time lag T= 2h 20m
Caption: jumper on, jumper off
•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 11,5V during battery-assisted operation
- battery fuse fault
- 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<11,8V
- high output voltage Uaux>14,7V

www.pulsar.pl PSBEN10A12C

- high battery voltage Uaku>14V (during battery test)
- failure of the battery charging circuit
- polymer fuse PTC activation
- exceeding the PSU nominal current
- failure in the battery charging circuit
- activation of the over voltage protection OVP
The technical outputs have been implemented with galvanic isolation between the PSU’s systems and the
attached devices.
Fig. 6. Electrical diagram of the technical outputs.
•TAMPER - output that indicates tampering with the PSU enclosure:output with volt-free (potential-
free) contacts indicating the door status and PSU detachment from the mounting surface. NC contacts: the
PSU is locked and fixed to the dedicated surface.
3.6 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. If voltage appears at the EXT IN input, it will cause generating a PSU
failure, storing the information about the event in the internal memo 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. 7. 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 type or tamper may be used as a source of the signal.
Fig. 8. Examples of connections.
In the option with tamper switches, the V
EXT
jumper must be on. It polarises 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 V
EXT
jumper must be on and the connections are to be made accordingly to the
diagram below.
