Technical description.
1.1. Application.
The ZUP-230V battery backup power supply provides the 230V uninterruptible voltage from the
mains or after its failure, from the DC/AC 230Vac inverter powered from the internal 24V battery bank.
During power failure, the total power is taken from the battery, its presence and efficiency is an
essential element of the power supply’s operation.
The power supply is not an UPS. Most fire protection devices supplied with 230V voltage during
supervision stay in standby mode - no power is consumed. The organization of the power supply’s
work takes into account this fact by setting specific time periods of the inverter's activity, while it takes
energy from the battery. Apart from those time periods the battery is relieved while waiting for a fire
alarm. This allows to extend the supervision time to 72h while maintaining the readiness to operate
powered devices with full power (depending on the type 400 ÷ 1500W).
The power supply enables 230V voltage distribution among 4 various types of receivers requiring
taking, switching or disconnection of power at a given time, depending on a function being performed,
after receiving a signal from outside (e.g. fire alarm). Response times for individual types of outputs
can be set by a user in a wide range by using slide switches. The main application of the ZUP-230V
power supplies includes:
•aeration gates;
•shunt trips of fire protection circuit breakers;
•self-locking, two-way actuators of shutting off dampers of fire ventilation;
•drives of the fire zone separating gates;
•spring actuators of fire protection shutting off dampers;
•blinds of ceiling smoke tanks;
•smoke exhaust fans running after a shutting off damper goes to the opening position;
•self-locking, two-way actuators of fire protection shutting off dampers, closed when a fan
stops;
•devices started in a cascade sequence to reduce the inrush current.
In addition, the 24Vdc uninterruptible voltage of 100W is available to supply other fire protection
devices.
The power supply meets the requirements of the EN 54-4: 2001 + A1: 2004 + A2: 2007 and EN
12101-10: 2007 and the Ordinance of the Ministry of Interior and Administration of the 20 June 2007,
the Book of Acts No. 143 item 1002, with an amendment No. 85 item 553 of 27/04/2010.
In addition, the power supply meets the requirements of the Regulation of the European
Parliament and the Council of Europe (EU) No. 305/2011 of the 9 March 2011. (CPR - Construction
Product Regulation).

User manual ZUP-230V Nr dok. 0697.00.95-02.3 5/15
Fig.2. Simplified diagram of ZUP-230V power supplies.
The 230V power distribution block (ZUP) switches the power outputs of the AC-1, AC 2, AC-3 and
AC-4 external devices in accordance with their functions, while supplying the voltage from mains
(230Vac power) or from the inverter in the event of power failure. Each output is equipped with its own
fuse.
The diagram shows exemplary connection of the external device (ACTUATOR # 1) from the AC-3
output.
The suitable action of switching outputs and power is initiated independently when power failure or
it can be forced by a fire alarm signal (CSP input). The input can be operated from multiple locations
after setting the line control mode. You can also disable the line control mode, forcing a simple two-
state operation.
The correct supply of the whole packet is indicated by the green LED OPERATION.
The power supply inverter operates continuously, which reduces the time it takes to switch from the
mains to the battery operation mode. Its starting and backup operation takes place from the ZSP121N-
DR power supply output. Then the ZINW-1 connector and the corresponding yellow LED on the ZUP's
power supply packet are on.
In case of necessity of loading the inverter (e.g., when power failure), its power is switched directly
onto the battery bank. The ZINW-2 connector is connected and the corresponding red LED on the
power supply packet are on.
Such the way of operation allows for independent supervision of the battery bank; its charging,
voltage and current measurement, resistance measurement and battery circuit continuity monitoring.
The inverter is connected directly to the battery only when significant current is required. It is also
possible to completely disconnect it after discharging the battery, which prevents it from damage.
The ZSP121N-DR power supply, in addition to the functions related to supervision of the battery
and powering the electronic circuits, allows for connecting additional external devices powered with
24V (OUT1 output) and for output of the binary signal (relay outputs), general fault (GEN FLT) and

User manual ZUP-230V Nr dok. 0697.00.95-02.3 6/15
mains power failure indication (MAINS FLT). In addition, the power supply can take one external fault
signal (EXT FLT).
In standard, the power supply also take a signal on its INT FLT input on a fault from the ZUP power
supply packet (outbound output) by transferring it to the general fault indication output (GEN FLT). The
power supply also triggers the LED indication on the box door. The green LED MAINS indicates the
presence of the mains power and the yellow LED FAULT is on simultaneously with the GEN FLT
signal indication.
The detailed description of the ZSP121N-DR power supply operation is included in its separate
User Manual.
Note
On the cabinet doors instead of the MAINS and FAULT descriptions, the following pictograms can
be used, respectively: and
Functioning of outputs.
Note
The basic operation of the 230 V outputs of the ZUP-230V power supply has been described
below. It is possible, after prior arrangement, to produce such a version, in which outputs will present
other time dependencies and in particular, several outputs will have the same functionality. This allows
for direct connection of several loads, which should be powered in the same way.
Output AC-1
The AC-1 output is intended for devices that after a power failure and during a fire alarm require
maintaining the 230V voltage for some time, e.g.:
- aeration gate drive (activated by a separate fire alarm signal, but it requires 230V power to
operate);
- shunt trips of fire protection circuit breaker (it is activated manually with a button, but requires
the 230V power to operate).
Fig.3. Voltage timings for AC-1 output.
The voltage at the AC-1 output is always present when the mains voltage is present and for a
preset T1 time after its disappearance and additionally during a fire alarm in the absence of the mains
power for the T2+T3 time. When switching from the mains power to the inverter operation and vice
versa, the output has a temporary voltage drop (about 150ms).
If the fire alarm occurred already after the inverter turned off (the T1 time counted down), the
inverter restart takes place with some delay: 2s is the time to recognize the alarm occurrence and the
next 10s is the time needed to start the inverter
Description of times that can be set by a user.
A detailed way of setting times is provided in point 5.7.3.
The time T1 can be set from 1 minute up to 8 hours, which also determines the maximum time of
battery operation after power failure
The time T2 can be set from 1 up to 6 minutes and from 1 up to 6 hours, which also determines the
maximum time of activity of the power supply after a fire alarm. If a fire alarm occurred during the
countdown of the T1 time, i.e. after the mains power failure, the countdown of the T1 time is

The time T3 results from the operation of the AC-4 output and it can range from 5 up to 65s.
Warning. Separate use of T2 and T3 times is included in the AC-4 output description.
Outputs AC-2A and AC-2B
The AC-2 output is intended for devices whose state is switched by a fire alarm signal, e.g.:
- self-locking, two-way actuator of shutting off damper of fire ventilation;
- drive of the fire zone separating gate;
or that can be activated during the fire alarm, e.g.:
- aeration or smoke exhaust fan switched on during a fire
Fig.4. Voltage timings for AC-2 output.
A fire alarm causes voltage loss at the AC-2A output (if present, i.e. when the mains present) and
the appearance of voltage at the AC-2B output (regardless of whether the mains is present). The
voltage on this output is maintained for a certain period of time T2+T3 (see the description of the times
of the AC-1 output), so that the actuator can change its state.
The response to a fire alarm always takes place with a delay of ~2s required for its correct
recognition. If a fire alarm occurred with the inverter turned off, it will be restarted with an additional
delay of about 10s.
Return to the safe position, i.e. the correct position before the fire alarm occurs (voltage present at
the AC-2A output and no voltage at the AC2-B output), is possible when the mains power present and
when is no fire alarm.
Output AC-3
The AC-3 output is intended for devices whose condition is backed-up by means of the external
power source and, which after a fire alarm appears, independently switch in a safe position by
switching it off, e.g.:
- spring actuator of fire damper;
- blind of ceiling smoke tank.

Fig.5. Voltage timing for AC-3 output.
If the voltage was present at the AC-3 output, it disappears after a fire alarm occurred for its
duration, but not shorter than T2+T3 (see the description of the times of the AC-1 output). The
response to a fire alarm always takes place with a delay of ~2s required for its correct recognition. The
voltage recovery at the AC-3 output is possible when the mains present and when is no fire alarm. The
voltage on this output is additionally maintained also after the mains power failure in the absence of a
fire alarm, so as not to unnecessarily move the devices to the position appropriate for the fire alarm
only due to the power failure. The voltage maintenance in this state is limited by the maximum battery
life T1.
When switching from the mains to the inverter operation, there is a temporary voltage drop on the
output (about 150ms).
Outputs AC-4A and AC-4B
The AC-4 output is intended for devices that should start operating with some delay after a fire
alarm, e.g.
- smoke exhaust fan, which can be activated only after passing the shut-off valve to the fully
open position;
- self-braking, two-way actuator of fire ventilation shutting-off damper, which should close the
damper only after stopping the fan.
- cascade-operated devices to reduce the inrush current.
Fig.6. Time waveforms for AC-4 output.
The AC-4 output has the AC-2 output functionality. The only difference is the additional delay in
switching after the fire alarm is recognized by the T3 time (see the description of the times for the AC-
1 output).
The response to a fire alarm always takes place with a delay of ~2s required for its correct
recognition. If the fire alarm occurred with the inverter turned off, it will be restarted with an additional
delay of about 10s.

Installation.
5.1. General notes.
The place where the power supply should be installed should be chosen so as not to expose it to
the mechanical damage, and to not exceed the permissible parameters of temperature and air
humidity. If possible, the power supplies should be installed in fire-partitioned areas (e.g. electrical
switchboards, technical rooms, cable shafts, etc.).
The power supply cabinet can be attached directly to the wall through the four holes in its rear wall
or with four spacers. The location of the fixing holes is shown in Fig.1. Use metal bushings and steel
screws for mounting. PVC dowels should not be used. In the case of direct hole mounting in the rear
wall of the cabinet, it is advisable to remove the inverter first by loosening the two nuts at its bottom,
slightly deflecting it and sliding it downwards.
The accumulator bank, due to its weight and dimensions, should be placed in the cabinet as the
last element; after all cable connections have been made.
Note.
The selection of wires in power and control systems for the fire protection equipment should take
into account the §187 of the Regulation of the Minister of Infrastructure of March 12, 2009 (Journal of
Laws No. 56, item 461) regarding technical conditions for buildings and their location, together with
later changes.

User manual ZUP-230V Nr dok. 0697.00.95-02.3 11/15
5.2. Connecting mains
The mains power cable with a minimum cross-section of 3×1.5 mm2, after passing through one of
the glands in the casing of the power supply, should be connected to single-track connectors, as
shown in the Fig.2.
Note.
The mains connection must be made as a permanent installation with the continuity of the neutral
line (N). The installation switch described below must be in the active line (L).
The power supply is not equipped with its own mains switch, therefore it is required to use a special
installation switch outside the power supply. The switch should also be used as an overload and short-
circuit protection device and allow to power the devices of high inrush current. We recommend using
the S301 C16A installation switch. This switch should be clearly marked as being used in the fire
system and cannot be used simultaneously in other circuits.
Warning.
Switching on the mains with a switch located outside the power supply can only be performed with
the fully assembled internal cabling of the power supply unit, including the connected and correctly
installed inverter. It is unacceptable to leave the 230Vac power plug disconnected from the inverter
output.
5.3. Connection of external AC output circuits
The external connections cables should be run through the selected holes in the cabinet's body
(after removing the jumpers) and fastened by twisting the appropriate glands. The cables to be
connected to the AC-1, AC-2, AC-3 and AC-4 outputs, after fixing them in the glands, should be led in
a large arc in the inverter plane before they are fixed by cable holders and connected to appropriate
terminals of the ZUP power supply . The external cable insulation should be removed directly behind
the cable holder. To make the connections of 230Vac power in the fire protection systems, 3-wire
cable of the HDGs type 1.5mm2 is recommended. For devices made in the 2nd class of insulation, it is
possible to use 2-wire cables, without using the connection with the PE bus bar.
Several loads can be connected to the power supply at the same time. The sum of their power
cannot, however, exceed the maximum power indicated for a given execution device. Attention should
be paid to the nature of the load provided by some loads. For example, induction motors can take
significant current when starting, which can lead to a blown fuse placed on a given output or prevent
proper start of the inverter. In this case, it is possible to use a soft starter system (so called soft-
starter), for example, the ZUP-MS type of the MERAWEX. However, a user is asked to consult the
manufacturer, due to different nature of loads, which may require setting individual device operation
parameters.
5.4. Connection of additional outputs
These connections concern the outputs of the ZSP121N-DR power supply shown in Fig.2. It should
be noted that all signal outputs and inputs are referenced to the negative output terminal of the power
supply. A detailed description of the outputs of this power supply is included in a separate User
Manual.
From the output OUT1 of the ZSP121N-DR power supply, only current of the values described in
the table Basic operating parameters of power supplies can be taken (point 1.2 Technical data).
5.5. Connection of battery bank
The battery bank, placed with its terminals from the side of the casing door, should be connected
with two cables that are already led out of the power supply, paying particular attention to the polarity:
red cable to the positive pole of one battery, blue to the negative of the second one. Finally, connect
the both batteries with each other, by means of the cable (connector) provided by the manufacturer.
Incorrect connection can lead to destruction of the power supply.
The battery should be connected with the battery disconnector switched off and its fuse removed.
Although each of the component devices (the ZSP121N DR power supply, ZUP and inverter) has its

User manual ZUP-230V Nr dok. 0697.00.95-02.3 12/15
own fuse, the common disconnector enables reliable disconnection of the battery from the entire
power supply.
All connections should be made carefully, remembering that during the battery operation (when no
mains power) the current consumed by the inverter can reach up to 80A.
In order to properly compensate for the temperature of battery floating voltage, the temperature
sensor of the ZSP121N-DR power supply should be placed between the side walls of the both
batteries.
5.6. Connection of alarm input from fire alarm control panel (CSP).
The fire alarm input from the CSP can be set both in the operating mode with parameterization in
which the resistance of the signal line is monitored during both the supervision and alarm time as well
as in the normal binary input operation mode. In both cases, however, it is required that the
parameters of the control circuit be within certain specified limits:
- for the input with parameterization of the resistance value, taking into account the resistance
of connections and leakage resistance (between the lines) cannot differ by more than 10%;
- for the binary input, the short-circuit resistance cannot be higher than 1kΩand the leakage
resistance (between lines) must not be lower than 100kΩ.
If these values are exceeded, the power supply signalizes the WYUSZ fault.

Switching on the battery switch (without mains) should not cause a permanent reaction of the
power supply. The correct starting (with the battery connected and the mains on) should result in
appearing the voltage on the AC-1 output. After power failure, the voltage should be maintained for the
time T1.

With the parameterization of the fire alarm input set, its failure activates fault signalization, which
should disappear after connecting a 10kΩresistor. In this state, connection of a 1kΩresistor is
recognized as occurrence of a fire alarm, which results in switching off the voltage from the AC-2A
output. The subsequent disconnection of the 1kΩresistor (disabling the fire alarm) should result in the
output on the AC-2A output, but only after the countdown of the time T2+T3.
5.7.3. Setting time
There are two slide switches on the 230Vac voltage distribution packet that allow you to set all
three times to organizing the activation of the AC-1, AC-2, AC-3 and AC-4 outputs of the power
supply.
Time T1:
- maximum battery life after power failure (from 1min up to 8h)
Setting:
- sum of individual settings: 1, 2, 5, 10, 30min and 1, 2, 5h.
Example in picture: (1+5+10)min + (1+2)h = 3h and 16min
Time T2:
- maximum time of power supply activity after a fire alarm (from
1min to 6min and from 1 up to 6h)
Setting:
- sum of individual settings: 1, 2, 3 and unit selection: min. or h.
Example in picture: (1+2)min = 3min
Time T3:
- delay of AC-4 output operation (from 5s up to 65s)
Setting:
- sum of individual settings: 5, 10, 20, 30s
Example in picture: (5+30)s = 35s
The absolute values of the set times depend on the construction and the required way of powering
a specific object.
Factory settings: T1: 5min T2: 5min T3: 5s

Installation and connection.
The power supply has been designed for mounting on a TS-35 rail and for use with battery banks.
Releasing the latch on the rail is possible by pressing the lever over the power supply with your fingers
or by pulling it down using a screwdriver inserted into a rectangular hole under the power supply.
Removing the power supply is possible by its slight deviation from the rail towards yourself and

User manual ZSP121N-DR Nr dok. 0696.00.95-02.0 Strona 4/8
upwards. Mounting can be done in the reverse order, also without the use of a lever, by snapping the
bracket on the rail.
The power supply must be connected to a permanent installation by using a protective conductor
and taking into account the L, Nand PE markings. It is recommended to equip the installation with a
surge protection system. The power supply voltage should not be disconnected with the main fire
protection switch. It is required to install in the power circuits, outside of the power supply, an installation
switch with a nominal current of at least 3A. The power box and the circuit breaker should be marked
with red color and the power supply number. One switch should protect one power supply. The switch
mounted on the casing of the power supply can be used for testing purposes –to check the voltage
supply during power failure.
After making the remaining connections (24V voltage outputs and signalization circuits) and after
connecting the external LED signalization harness and possibly the tamper, the batteries should be
connected as the last item.
The power supply has been designed for cooperation with two maintenance-free batteries, which
should be placed in its immediate vicinity. The end of the temperature sensor of the power supply
should be inserted between the two batteries, which afterwards should be maximally pushed together.
Pay special attention to the polarity of the power supply and battery connections. If the connection is
wrong, the battery circuit fuse will be damaged. The following figure shows the polarity of the connected
BAT battery. Firstly, the batteries should be connected to the power supply packet and then connected
to each other.
The power supply is adapted to connect an external LED signalization located, for example, on the
cabinet in which the power supply and batteries have been installed.
It is possible to select between two levels of charging current limitation, battery banks depending on
their capacity. The details are included in the Electrical parameters table. Simultaneously with
switching the level of the charging current limitation, the threshold of the permissible resistance of the
battery circuit Ri max is switched over.
By default, a jumper is mounted on the CL connector, which sets the higher charging current and the
lower value of the resistance Ri max.
