1.1. General description.
AC/AC PSAC 04244 power supply is using for supplying alarm systems devices requiring AC voltage of 24 V with overall
efficiency of 4A@24V AC.
Basic features of the power supply:
• 4 outputs protected independently by fuses or PTC: failure (short circuit) within the circuit of any of the outputs will
result in burnout of the safety device insert/actuation of the PTC and isolation of the circuit from power supply.
• regulation o the output voltage: in case of installation, where significant drops in voltage in effective resistance of
receiver supply cables can occur, it is possible to correct the value of output voltage with the help of U1/U2 jumper,
independently for each AUX output.
• optical work signalling informing about the condition of outputs and/or failure.
• AW technical output informing about output failure (activity of the SCP), used for remote control of the activity.
• protection: short circuit protection (SCP), overload protection (OLP), overheat protection of the transformer (OHP)
• metal casing (colour – RAL 9003) with signalling panel.

2. Installation .
2.1 Requirements.
AC/AC power supply shall be mounted by the qualified installer having appropriate (required and necessary for a given
country) permissions and qualifications for connecting (operating) 230V/AC installations and low voltage installations. The
device shall be mounted in closed rooms, according to the environment class II, of the normal air humidity (RH=90% max.
without condensation) and the temperature within the range from 10°C to +40°C. The power supply shall operate in a vertical
position so that free and convectional air flow through ventilating holes of the casing is guaranteed.
Before installation is started, the balance of the power supply load shall be performed. During normal operation the
sum of the currents consumed by the receivers cannot exceed I=4.0A@24 V AC. Because 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 shall be guaranteed. Moreover, the user shall be informed about the method of isolation of the power supply from
the power voltage (usually through assignment and marking of an appropriate fuse in the fuse box). The electrical system shall
be made in accordance with valid standards and regulations.
2.2 Procedure o installation.
1. Be ore initiating the installation it is necessary to ensure that the voltage in the 230 V power circuit is
disconnected.
2. Mount the power supply in the selected place and guide connecting conductors
3. Connect the power cables (~230 V AC) with L N power supply terminals. Connect the earth conductor to the clamp marked
with earthing symbol. The connection should be performed with 3 core cable (with yellow green PE protecting conductor).
Power conductors should be connected to proper terminals, through seal wire.
The circuit o the shock protection shall be per ormed with a particular care, i.e. the yellow and green
protection wire o the power cable shall be connected rom one side to the terminal marked by the
symbol o in the casing o the power-supply. Operation o the power-supply without the properly
made and ully operational circuit o the shock protection is UNACCEPTABLE!
It can result in ailure o devices and electric shock.
4. Connect the cables of consumers to the AUXx COM terminals on LB4/24V/27V/AW fuse block.
5. If necessary, connect device cables (alarm unit, controller, signaller, etc.) to technical outputs of the power supply:
AW output signalling the activity of the fuse (output of the LB4/24V/27V/AW fuse block).
TAMPER output signalling opening of the power supply casing.
6. In case of installation, where significant drops in voltage in effective resistance of receiver supply cables can occur, it is
possible to correct the value of output voltage with the help of U1/U2 jumper, independently for each AUX output.
7. Connect 230 V AC supply.
8. Check optical signalling of the power supply operation: LED L1÷L4 diodes (green) should be constantly illuminated.
9. Close the casing after installing and verifying the correctness of the power supply activity.
3. Monitoring o the o power supply.
The power supply is equipped with optical signalling the status of operation. Presence of voltage on power supply outputs is
signalled by illumination of green LED diodes on the plate of LB4/24V/27V/AW fuse block. Failure is signalled by red LED diode
[!] AW. Condition of the power supply may be controlled remotely by AW technical output.
3.1 Optical signalling.
• LED L1….L4 green diodes signal the supply status on AUX1…..AUX4 outputs.
In case of loss of voltage on the output (burnout of the fuse/ activation of the PTC), appropriate LED diode stops to be
illuminated (L1 for AUX1, L2 for AUX2, etc.).
• LED [!] AW red diode indicates failure of at least one AUX output (number of the output is signalled by the green
LED).
3.2 Technical output.
The power supply is equipped with signalling output, enabling to submit information about the failure or sabotage.

8
• AW output signalling the activity of the fuse (output of the LB4/24V/27V/AW fuse block).
AW technical output during the proper operation of LB4/24V/27V/AW fuse block is connected to the mass (GND), whereas in
case of damaging one of the fuses, the output shall be disconnected from the mass. This status is also signalled by the red L
AW
diode.
• TAMPER - output signalling opening of the power supply casing, output of the potential free contact signaling the
status of the power supply doors, power supply closed: NC, power supply open: NO.
4. Service and operation.
4.1 Overload and short-circuit o the power supply output.
Outputs of the AUX1÷AUX4 power supply are protected against short circuits with fuse element safety device (inserts)
or PTC. In case of damaging fuse element safety device it is necessary to exchange the fuse (compliant with the original).
If PTC polymer fuses protection was chosen, then automatic disconnection of the output voltage was signalled by
switching off the green diode. It is then necessary to disconnect the load from the power supply output for the period of about
1 min.
Loading the power supply with the current exceeding Σ4.0A@24 V AC (110% ÷ 150% of the S power) results in the
failure of the F fuse in the 230 V AC circuit and/or F1÷F4 fuses. In case of failure it is essential to exchange the fuse, compliant
with original.
4.2 Maintenance.
All maintenance procedure may be performed after disconnecting the power supply from the power network. The
power supply unit does not require performing any special maintenance procedures, however, in case of significant drop of the
dustiness, it is only essential to remove the dust from the interior with the help of compressed air. In case of changing the fuse
it is essential to use substitutes compliant with the original parts (recommended).
WEEE MARKING
The used electric and electronic device may not be thrown out together with common household
wastes. According to WEEE directive, binding within the EU, in case o used electric and electronic
devices separate means o utilization should be utilized.
