INTRODUCTION TO THE PREMIER POWER PACK PSU
The Premier Power Pack is an EN54 compliant Power Supply, intended to power ancillary fire alarm equipment.
It incorporates a small LCD screen that will give information about the Power Supply status (such as output
voltage, output current, charger voltage etc).
It also displays basic information via its LEDs (Power/General fault / earth fault & Battery fault). These LEDs are
located on the panel door, and also on the controller PCB itself.
The power supply has a 3 state charger. It will initially supply a BOOST charge current, until it has detected that
the battery is close to full charge, then it will switch to FLOAT charging. If it detects flat or missing batteries, it will
switch to PULSE mode, until it detects good batteries.
The PSU monitors batteries for High Internal resistance, and will report a fault if it detects a resistance that would
prevent the PSU giving its rated output.
The power supply will prevent battery deep discharge by disconnecting the batteries when they reach their final
voltage under a mains fail condition.
The Power pack PSU is also available as a “CIE version”, used to power fire alarm panels. This version of the PSU is
normally supplied without the current measuring feature.
The “Control panel” version does not have the LCD fitted, so will communicate its status via its internal LEDs only.

CHANGES TO EN54-4 (THE FIRE ALARM EQUIPMENT POWER
SUPPLY STANDARD)
In 2006 the Fire alarm Power Supply Equipment standard changed, adding the requirement that a PSU should
monitor the internal resistance of its batteries, and give a warning when it is above a certain level.
The reason for this is that when a battery’s internal resistance increases, it will reach a point where the battery
will no longer be able to supply the rated output voltage of the PSU under full load conditions. So under a mains
fail condition, the Power supply, running on batteries only, could not supply it`s rated load.
For Example, if a 5 Amp power supply has batteries with 2 ohms internal resistance, when running on batteries,
and supplying full load, there would be a 10V (V=IxR = 5 x 2 = 10 Volts) drop across the battery, meaning that the
output voltage would be outside the working range of the power supply.
The Premier Power Pack range of power supplies will give a Battery Hi Internal resistance fault when the internal
resistance for that power supply’s rating is close to the level that would cause the working voltage to be out of
range.
NOTE: Batteries reporting a high internal resistance WILL NOT BE CURED BY CHARGING ALONE. Either replace the
batteries, or discharge & charge 3 or 4 times (Note that this will take several days, and is not guaranteed to cure
the problem)

This screen gives information about the battery & charger circuit. The Battery IMP(edance) is the internal
resistance of the battery , explained in the recent changes to EN 54-4 section.
The Charger Voltage will be the voltage at the battery terminals.
The Charge Type gives the current charging method. The methods used are:-
BOOST –Constant current charge of 920mA. Used when batteries are flat
FLOAT –Float charge is applied as the batteries approach a full charge
PULSE –used when the voltage at the charger terminals is less than the final voltage. Used to check if the
batteries are present.
OFF –Charger is turned off when no mains is present

The Battery state indicates whether the batteries are:-
GOOD –Batteries are OK
HI IMPEDANCE –High internal resistance detected
FLAT –Battery voltage below final voltage. Batteries should be replaced
REMOVED –Batteries have been disconnected

LED EXTERNAL
The PSU external LEDs are:-
Power (GREEN) Steady = mains present
Flashing = Mains fail
General Fault OFF = No fault present
ON = Output fuse blown or removed, or mains low/fail (with flashing power good LED)
Earth Fault OFF = No earth Fault present OR earth monitoring disabled
ON= Earth fault Detected. Check LCD screen for further info.
Battery Fault OFF = Battery OK
ON = Battery Fault
LED INTERNAL
These are the same as the external LEDs. These are the only indications present when the PSU is used in a Control
Panel. The General fault is labeled as charger fault.

MOUNTING THE POWER SUPPLY
The Premier Power Pack range of Power supplies are suitable for indoor use only.
Before fixing the Power supply to the wall, consider the planned cable entry. The Premier Power Pack PSU has
top & bottom 20mm cable entries. If other entries are required, the box can be carefully drilled before fixing to
the wall.
Fix the Premier Power Pack to a suitable sturdy Flat surface. Fitting the PSU at eye level will allow the panel`s
display to be easily read. Use Fixing screws suitable for the chosen surface, remembering that with batteries
fitted, the Power supply will be quite heavy.
If additional cable entries have been cut into the box, ensure that all swarf has been removed. The cutout will
probably have a sharp edge that could damage the cables. Use suitable insulation to cover the sharp edges.

ELECTRICAL CONNECTIONS
ELECTRICAL SAFETY MEASURES
A licensed electrician must be present to connect to the mains if it is a fixed installation.
Connecting equipment to a consumer unit is potentially hazardous. Ideally, do not do this work alone.
Alternatively, advise a colleague that you are about to undertake this work, and that you will call them
back at a set time.
Check that the power supply, its cables, plugs and sockets are in good condition before installing. If
there are signs of damage, contact your supplier to arrange a replacement.
Electricity can be dangerous. Conductive materials can cause a high short-circuit current which could
cause serious burns.
Do not use any kind of metal equipment (Eg Screwdriver) inside the PSU without first unplugging the
equipment.
NOTE: When the Power Pack is operating normally, i.e. not being tended by service
personnel, the access door must be closed and locked. Also the electrical connectors on
the power supply cage must be insulated using the provided plastic cover. After locking
the access door, the key MUST be removed and ONLY held by the responsible person and
/ or the service personnel. It must under NO CIRCUMSTANCES be held by the user.
NOTE: Connecting this power supply to a fixed mains connection should only be carried out by a qualified
electrician. The PSU is Class 1 Equipment and MUST be earthed.
BATTERIES
Batteries should be recycled. Leave the battery in a suitable recycling bin or return it to the supplier in
the original packaging of the new batteries. Consult the new battery instructions to obtain more
information on this.
Do not dispose of batteries by throwing them in fire, as they could explode.
Do not open or cut batteries; they contain an electrolyte that is toxic and harmful to the skin and eyes.
In order to prevent personal injury caused by hazardous currents, avoid wearing wristwatches and
jewelry such as rings when replacing batteries. Use tools equipped with insulated handles.
When replacing batteries, use the same number and type of batteries installed in the equipment.
Consult your supplier to obtain information on battery equipment replacement and recycling batteries.

CONNECTING THE MAINS & BATTERY
The Power Supply should be connected to 230V AC by a 3A rated spur to the fuse box with 1.0mm2 to 2.5mm2 3-
core cable. Nothing else should be connected to this supply
The mains input is to be connected to the PSU Cage. The Live, Earth and Neutral connections are marked on the
switch mode cage.
The incoming mains cable should be kept separate from the other cables to help minimise mains interference.
The two batteries are wired in series.
The +ve of one battery is connected to the red battery charger lead.
The –ve of the other battery is connected to the black battery charger lead.
The –ve of the first battery is connected to the +ve of the second battery using the FUSED link wire supplied.
