1.2 Pre-installation check list
Before selecting the location for the HLS PS Series, DO make
sure that:
a) The ambient temperature is in the range:
-5 ºC to 40 ºC
b) The relative humidity is bellow:
93% (non-condensing)
c) DO NOT locate the equipment where it is exposed to high
levels of moisture.
d) DO NOT locate the equipment where there are high levels of
vibration or shock.
e) DO NOT site the HLS PS Series where there would be
restricted access to the internal equipment and wiring
connections.
1.3 Transient protection
As with all solid state devices, this system may operate erratically
or can be damaged if subjected to lightning-induced transients.
This equipment contains transient protection devices. Although
no system is immune from lightning transients and interference,
for these devices to function correctly, and to reduce
susceptibility, this equipment must be earthed correctly.
The use of overhead or outside aerial wiring is not recommended
due to the increased susceptibility to nearby lightning strikes.
The HLS PS Series is wall mounted in a position, which allows
clear visibility of indicator leds. The height above floor level
should be chosen such that the indicators are just above normal
eye level (approximately 1.5 metres).
1.4 Cleaning
The HLS PS Series case may be cleaned periodically by wiping
with a soft, damp lint-free cloth.
Do not use solvents.

2.1 HLS PS25 / HLS PS50 characteristics
These Power Supplies Units are designed to comply with the
requirements of EN54-4 in order to provide fire control systems with
backup supply.
The HLS PS Series operates at 115/230 Vac and 50/60 Hz.
Both Power Supply Units, HLS PS25 and HLS PS50, are very similar:
they consist of a 2x65W, which means 130W in HLS PS50 and 1x65W
in HLS PS25 and a standard module control which supervises the entire
power supply.
HLS PS25 and HLS PS50 power supplies provide 2.5 Amp and 5 Amp
respectively and 300mA to 600mA of them are dedicated to charge
batteries. These power supplies are able to supply either up to 1.10
and 2.20 Amp current at each PSO1 and PSO2 outputs. This is the
default set up (DIP SW1 ON, up position). However, power supplies can
also supply all the current in only one output by placing the DIP SW1 in
the down position, OFF. This way, all the current (2.20Amp or 4.40Amp
respectively) will be supplied through PSO1 output
.

2.2 Battery
DIP SW2 allows selecting the maximum current of battery load,
depending on the batteries inside the power supply unit box.
With DIP SW2 in ON position (up), 7Amp/h batteries can be charged
at 300mA. When DIP SW2 is in OFF position (down), 20Amp/h
batteries can be charged at 600mA.
In this example,
DIP SW2 is in OFF position
(down) and the load current will be limited to
600mA.
DIP SW3 . This DIP switch is in ON position (up).
For future use.
DIP SW4 . For future use.
2.3 Fault relay
The Power Supply has a fault relay to report any anomaly to a remote
control unit.
Any fault has a delay of 30 seconds from the fault signal to fault relay
confirmation, except when there is a mains AC loss, which will be
indicated after an 8-minute delay to avoid faults from intermittent
power cuts.
In stand-by, the fault relay is energized indicating its normal operation.
In case of any fault, the relay deactivates after the confirmation time.
Fault relay operation
FAULT switch with three terminals
Terminal 1 (left) C common
Terminal 2 (centre) NC or Normally Closed
Terminal 3 (right) NO or Normally Open
Fault relay operates as follows:
No supervision (without power) or in fault condition
Between C and NC —> continuity
Between C and NO —> open circuit
Operating with supervision without faults, i.e. in NORMAL STATE
Between C and NC —> open circuit
Between C and NO —> continuity

2.4 Control Unit Connections:
The following 4 connectors are placed at the top of the Control Unit:
FAULT (C) Fault Relay Common
FAULT (NC) Normally Closed Contact
FAULT (NO) Normally Open Contact
The fault relay may be linked to an analogue
input module to report any fault to a third
equipment like a FACP (Fire Alarm Control
Panel).
IN ALARM
(+)
IN ALARM (-)
Alarm input to disable, momentarily, the battery charger and be able to supply 300-
600mA from battery load to the outputs. For this, it is necessary to link both IN
ALARM terminals by means of a jumper or short-circuit.
When this input is activated, the control unit will have an extra current of battery load
0.3 A or 0.6 A, depending on the DIP SW2 for outputs. Thus, if the power supply is in
Overload (Imax) state, the indication will disappear by activating this input, provided
that the excess current is the current which is supplying batteries.

TEST The test button allows performing a led test and makes a real test of batteries forcing
them to supply current of 1A approx. for a minute. In case batteries fail, a Battery fault
will be reported. The HLS PS Series will supervise automatically the battery each 3
hours. If the battery load is in normal condition, the fault signal will disappear.
EN54 - 2
Section 8.2.4 requires that any Earth fault which may affect an obligatory function
should be indicated independently.
The cable size should be calculated according to the maximum length, the maximum
voltage drop supported by devices and the minimum voltage of battery system.

2.5 Indicator leds:
ON Led
This led is ON when the Control Unit is powered.
Fault Led
Yellow led that is ON in case of a Power Supply Fault. When
this indication is activated, the C and NC contacts of the fault
relay will be closed.
MAINS SUPPLY FAULT Led
Power Supply is not detected by the Control Unit and it is
powered by batteries. The internal led BAT-DIS is also
activated.
The led is ON immediately after detecting power. However, the
fault relay signal and the FAULT led do not activate until the
power supply fault remains for more than 8 minutes.
BATTERY FAULT Led
Battery is not detected by the Control Unit or the battery voltage
is below 22.4 Vdc, i.e., the 50% of its capacity.
The FAULT Led and the fault relay signal are also activated.
In case the internal led LOW BAT is flashing it means that the
battery voltage is close to 22.4 Vdc.
When the battery voltage is lower than 20.4 Vdc, both outputs,
PSO1 and PSO2, and the Output 1 and 2 leds will indicate a
fault condition.
The FAULT Led and the fault relay signal are also activated
BATTERY CHARGER FAULT Led
This led is on when there is a battery charger fault.
