1. Technical description
This user manual refers to the power supply with remote indication of faults defined as the
mains fault and the battery fault. These two signals can be combined into a collective fault
indication – see the section 2.3.
In this respect it differs from the previous version, offering the collective fault indication
(including the mains fault too) and a separate signal about the mains fault.
Types of the available indications can be recognized by reading descriptions next to
connectors or on the wiring diagram (a sticker inside the casing).
1.1. Application
The power supplies are dedicated to uninterruptible supply of power in the range of 55W to 190W at
the voltage 24V to devices of fire detection and fire alarm systems, systems of smoke and heat control
as well as other fire protection devices, where compliance with EN 54-4:1997/A2:2006 or EN 12101-
10:2005, guidelines of VdS 2541:1996-12, 2882:2004-11, 2824:2004-03, 2593:2002-09 or the Polish
Ordinance (specified on the title page) is required.
The battery back up power supplies ZSP135-DR supply power from the utility power grid or – in
case of a power failure – from internal bank of VRLA batteries (known also as AGM or gel batteries).
They have two outputs, protected by fuses. During a transition from the mains power to the battery
power and vice versa there are no voltage dropouts on the outputs.
The power supplies fulfill the requirement of EN 54-4 to offer a collective fault indication by an
appropriate connection of relay outputs of the signals (see the section 2.3).
The power supplies can manage an external binary fault signal and optionally can be equipped with
the device to detect unauthorized opening of the door (see the section 4.3)

Exemplary outer layout of the power supply (ZSP135-DR-5A-1) and location of the mounting holes.
The detailed technical description of the power supply ZSP135-DR could be found in the technical
documentation, no. of the document 0404.00.91-01.4 section 2.
2. Set-up
During set-up apply directions of this manual
Mount devices in a place without direct insolation
Mounting and connecting could be carried out only without batteries
Observe proper polarity when connecting batteries
The device must be powered from the utility power grid with a protective earth
terminal
Check the quality of all done connections before switching the device on
2.1. Mounting
The power supply should be mounted in a carefully selected place, to minimize the risk of
mechanical damages and not to exceed allowable ambient temperature and humidity. Power supplies
of fire protection equipment should be mounted nearby this equipment to minimize voltage drop. If
possible, the power supplies should be mounted in rooms separated as fire resistant areas (e.g.
switchboard rooms, technical rooms, cable chutes)
The box should be mounted on the wall, using four holes in the rear side of the box. Before
mounting, one has to open the box, unscrew three nuts fixing the chassis of the power supply to the
rear face of the box and remove the power supply.
The empty box has to be fixed to the wall by 4 steel sleeves and screws. Wall plugs made of PVC
can not be applied. If there is a need to lead wires between the box and wall one has to fix enclosed
brackets to the box before mounting on the wall. Having the box fixed to the wall one has to mount the
power supply back. .
Location of the mounting holes is show in the section 1.2. Technical data.
2.2. Connections
One has to remember to connect the device to the permanent wiring using protective earth wire. It is
recommended to outfit the installation with a surge protection system. The input voltage should not be
cut off by the master fire protection switch.
The power supplies have no own mains power circuit breakers, so a dedicated, overcurrent and
short circuit resistant breaker of at least 3A current is required in the powering installation (outside the
power supply). The switchboard panel and breaker of the fire protection power supply should be clearly
marked (by red color and number of the power supply or by a proper description). One breaker should
protect one power supply. Using this breaker for other loads is impermissible.

User manual ZSP135-DR No. of documentation 0404.00.95-02.2 Page 5/12
The installation cables can enter the box from the top through three cable transits PG-11 and one
PG-9 (dedicated for remote indication cables). All connections should be carried out according to the
diagram inside the box (on the door). Holes of unused transits should be plugged by the plugs enclosed
to the device.

– look carefully at symbols next to the terminal.
*2) Selection of wires in power and control systems of fire protection equipment can be subject of local law and
regulations, e.g. civil engineering code and derived ordinances.

User manual ZSP135-DR No. of documentation 0404.00.95-02.2 Page 6/12
Batteries are delivered in separate transport packages. They should be connected with wires
delivered by the manufacturer. Before the connection the batteries have to be put on the bottom of the
box. First, connect the batteries to the main circuit pack of the power supply, and then connect each
with other. One has to pay due attention to the right polarity of the connection. In case of erroneous
connection of the battery circuit a fuse shall blow.
2.3. Implementation of the collective fault indication
Relay outputs of faults USZ SIECI (MAINS FLT) and USZ BATERII (BATTERY FLT) can be used to
implement the output of the collective fault indication. This will indicate on a single line occurrence of
any event covered by both signals. Either NO or NC contacts of the relays can be used. Both options
are shown on the picture below.
USZ SIECI
USZ BATERII USZ SIECI USZ BATERII
The visible pictograms representing the contacts of the relays refer to the state when the relays are
not activated (voltage free state). By the fail safe rule this is the state indicating a fault.
3. Switching on for the first time
If all connections have been carried out correctly, then after having the power supply connected to
the mains the indication LEDs ZASILANIE (MAINS), PRACA (OPERATION) (diodes 8 and 9 inside the
box on the circuit pack – see the picture and table in the section 2.2) and POWER (the diode no. 11)
should light up. Additionally, one should hear the sound of the relay attaching the battery bank to the
system. The attaching of the battery happens only when the battery bank voltage is greater than 20.5V.
During the switching on one should perform two checks.
3.1. Checking ability to back up output voltage.
Use a breaker in the electrical installation before the power supply ZSP135-DR to cut off the mains
power. The power supply should switch to the battery mode, keeping voltage on its both outputs. Check
it by whatever probe, e.g. a voltmeter or electric bulb.
This state is indicated by the blinking LED POWER in the door of the power supply. The relay USZ SIECI
(MAINS FLT) shall switch to the inactive state (contacts connected as on the pictogram next to the
terminal). The relay USZ BATERII (BATTERY FLT) shall remain activated. The state of a relay could be
checked, e.g. by an ohmmeter connected to appropriate contacts of the relay.
3.2. Checking the battery circuit
When the power supply operates at presence of the mains power, break the battery circuit by
disconnecting one of its wires. This state shall be detected during the first next test. It could last up to 10
minutes. Similarly, having the circuit connected again, the triggered fault indication shall be cleared
automatically, but no sooner as after the first successful test – which may require another 10 minutes
waiting.
This state should also trigger the indication FAULT in the door of the box and the indication BAT (the red
LED) on the circuit pack of the power supply. The relay USZ BATERII (BATTERY FLT) shall switch to the
inactive state (contacts connected as on the pictogram next to the terminal). The relay USZ SIECI
(MAINS FLT) shall remain activated. The state of a relay could be checked, e.g. by an ohmmeter
connected to appropriate contacts of the relay.

User manual ZSP135-DR No. of documentation 0404.00.95-02.2 Page 7/12
4. Operation
4.1. Introduction
Output voltages and state indication thresholds are factory preset. After having set up the power
supplies require ongoing monitoring by the staff to react to fault indication which may occur during the
operation.
4.2. Input of an external fault signal
The power supply can manage one binary external fault signal. To trigger this fault indication one
has to shorten input contacts of the signal. The contact denoted by the sign “-“ is connected to the
chassis (negative pole). The occurrence of the external fault is indicated by the blinking LED FAULT in
the door of the box and by the non-activated relay. If any internal fault occurs at the same time, then the
LED is on continuously. This event was assigned to the relay USZ BATERII (BATTERY FLT).
4.3. Device to indicate the opening of the door (option)
The power supplies ZSP135-DR optionally could be outfitted with the protection against
unauthorized access to the box interior. Opening the door (after having it unlocked) causes
disconnecting of the contacts of the sensor and triggers a fault indication – the blinking LED FAULT in
the door of the box and the non-activated relay. The indication doesn’t stop when the door is closed.
This event was assigned to the relay USZ BATERII (BATTERY FLT).To clear the indication one has to
press the contact of the sensor four times within the period not longer than three seconds. The LED
FAULT returns then to the state before the door opening. The indication function is reactivated
automatically after the door closing.
4.4. Indication of the state of operation
The power supplies ZSP135-DR have visual and remote indications of states. The indication
continues until the cause of the trigger ceases.
The visual indication consists of two LEDs located in the door of the box; the green LED is labeled
POWER and the yellow LED is labeled FAULT.
The remote indication consists of two sockets labeled USZ SIECI (MAINS FLT) and USZ BATERII
(BATTERY FLT). All of them offer three dry contacts, totally isolated from other circuits.

4.5. Maintenance
The device doesn’t require any special maintenance activities. During the normal operation one has
to take care only to keep the necessary cleanness in the proximity of the box.
It must be taken into consideration that if battery expected life is e.g. 12 years at temperature of
20°C, then it is 10 years at temperature of 25°C and drops twofold when temperature increases further
by 8°C.
Attention: CNBOP (a Polish notified body) and VdS recommend replacing batteries after 4 year of
operation irrespectively of their state.
4.6. Inspections
Frequency of inspections is regulated by provisions appropriate for the powered device, but shall
not be lesser than once a year. During an inspection two functional tests described in section 3. Switch-
ing on for the first time should be carried out. Additionally, it should be checked if a fault indication
triggered by the power supply is transmitted to the fire alarm control panel.

6. Remarks on the selection of the type of the power supply
Power supplies ZSP135-DR have various output currents and cooperate with internal batteries of
various capacities. The selection of the specific type should depend on requirements of the specific load
(powered devices).
First, one has to calculate the required battery capacity. To do this one has to take into account
consumption of current during various states of operation of the powered devices as well as additional
consumption for own needs during the mains power failure.
The minimal capacity of the battery bank can be defined with the help of the following formula:
QBAT = 1.25 ×[(ISB + IQ) ×TSB + (IAL + IQ) ×TAL + IACT ×T3]
where:
QBAT - battery capacity [Ah]
1.25 - safety coefficient to account for capacity loss after seasoning and wear-out
I
SB - current employed by loads during the standby [A]
I
Q- quiescent current [A]
T
SB - required standby time [h] (4h, 30h or 72h)
I
AL - current employed by loads during alarm [A]
TAL - alarm duration [h] (0.5h)
IACT - current employed by actuators during an alarm [A]
T3- duration of three full work cycles of the actuator [h]
Attention: the power supply requires some minimal battery capacity during the standby and alarm for its
own needs (IQ = 0.035A). This is 3.3Ah for the standby of 72h, 1.4Ah for 30h, and 0.20Ah for 4h.
Having calculated from the above formula the required capacity of the battery bank, one can use the
table in the section 1.1 to select the power supply, observing the constraint of the maximal capacity to
mount in the given power supply and choosing the standard value which must be greater than the
calculated minimal capacity.
Additionally, the following conditions must be met: ISB < Imax.a , IAL < Imax.b and IACT < Imax.b.
7. Additional information
7.1. Manufacturer’s remarks
The manufacturer reserves the right to introduce changes in the design and technology which shall
not impair quality of the product.
7.2. Cooperating devices
7.2.1. Tester
A tester of power supplies ZSP135 has been developed for the
service and maintenance staff. It allows reading values and states
recognized by the controller of the power supply without intrusion
into circuits of the power supply and without measurement
equipment. It is also possible to determine the state of the battery
bank during the test and to force a test outside the automatic
schedule.
7.2.2. Communication module
The communication module ZSP135-MK is another optional
outfit. It enables transition of data from the power supply via the
RS232 or RS485 interface. The read data include measured
values and states recognized by the controller of the power supply.
The module was designed to be mounted inside the box of the

User manual ZSP135-DR No. of documentation 0404.00.95-02.2 Page 12/12
power supply. Owing to the module the power supply ZSP135-DR can be visible in the Building
Management System GEMOS. The manufacturer offers integration with other systems.
More information on the cooperating devices shall be found in their separate user manuals.
7.3. Handling of the package and waste
The package of the product is made of materials which could be recycled.
Unused packages should be handed over to a dust collector, after having them
segregated.
The used out product constitutes non-hazardous waste, not to put into the general
waste container. Instead, it should be handed over to the local collector of the waste
electric and electronic equipment.
Professional handling of the waste electric and electronic equipment (WEEE) shall
limit negative effects of improper storage and processing of this waste on human health
and environment.
The used out batteries should be handled according to local regulations, e.g. introduced as the
implementation of the Battery Directive (Directive 2006/66/EC of the European Parliament and of the
Council of 6 September 2006). They are sealed, maintenance-free, valve-regulated (equipped with a
pressure relief valve) lead acid batteries. When used out they constitute hazardous waste, coded in the
European Waste Catalogue as 16 06 01*.
