Technical description.

1.1. Intended use.
Power supply with battery backup type ZUP-230V-BM supplies uninterruptible 230V power from the mains or, in the event of a power failure, 230Vac from a DC/AC inverter powered by an internal 24V battery.
The inverter used offers a high-quality stabilised sinusoidal output voltage of 230V 50Hz. The inverter can be loaded with any type of receiver (inductive, capacitive, resistive). The ZUP-230V-BM power supply is designed for operation in two modes: CSP and UPS. The CSP mode, working with the Control and Indicating Equipment, is intended to control the opening of gates which, in the event of a fire, in addition to their communication function, are used to help remove smoke from the building by acting as air gates. UPS mode can be used wherever an uninterruptible 230Vac power supply is required. The power supply additionally features an input for connecting an EPO (Emergency Power OFF) circuit breaker, allowing it to be switched off completely.
The basic versions of the power supplies with 400W, 700W and 1000W are mounted in the small cabinet (S). The power supplies in the M and L cabinets can additionally be equipped with an uninterruptible 24Vdc power supply output.

Power supply housings have hole plugs for cable glands prepared for mechanical removal during mounting:

• for S type cabinets:
  o in the upper part for 3 M16x1.5 glands and 2 M20x1.5 glands

• for M and L type cabinets:
  o in the upper part for 5 M16×1.5 glands and 7 M20×1.5 glands
  o in the bottom part for 3 M16×1.5 glands and 5 M20×1.5 glands

1.3. Technical data.
The table below is provided as a basis for meeting the requirements of the standards indicated:
− EN 54-4, which imposes a time limit of 24 hours for charging the battery to 80% of its capacity with the possibility of drawing Imax_a current for the needs of the supplied devices
(Imax_b is the maximum, momentary current whose drawing does not allow such charging) and the maximum additional resistance Ri max in the battery circuit;
− EN 12101-10, which defines the conditions for battery operation (when fully charged): waiting for the load (so-called supervision) during which the indicated current Imax_a may be drawn for 72h and the maximum short-duration current Imax_b for 180s.
In the columns of the table that are assigned to the currents described by the standards, for the 230Vac output, the power that can be drawn from this output, under the same conditions as the current, is entered.
The tables present only such combinations that result from possible configurations of the ZUP-230V-BM power supply (see 1.2.)

Note 1.
The power supplies in the S type housing cannot be equipped with 24Vdc output
Note 2.
The specified power values for 230V are the determined continuous load power for the table of EN 54-4 (with present mains supply) and for 180s operation for the table of EN 12101-10 for battery energy balance (battery operation, without mains supply).
Note 3.
The Imax_b current shown in the tables is limited by the fuse used (see table Basic electrical and environmental parameters).
Note 4.
It is possible to use batteries with other capacities between those indicated in the table. In this case, ask the manufacturer of the power supply to determine the Imax_a and Imax_b currents suitable for the battery used. The described conditions are met for operation in the so-called CSP mode, in which the PSU works with the control and indicating equipment. This mode of operation is described in more detail in
3.1. For operation in the so-called UPS mode (for a detailed description see 3.2) the conditions of the EN 54-4 standard are met, while the conditions of battery operation can be selected according to the needs of the facility where the power supply is installed.
An example load table for the following battery operating conditions is shown below:
− waiting time (ready to work) 8h;
− operating time at full power 180s;
− current drawn from the 24Vdc output 0.1A;
− 24Vdc output activation time 24h
Based on these assumptions and the required power from the 230V output, the minimum battery capacity can be determined. The conditions imposed by EN 54-4 define the possible load of the power supply at the actual mains supply (see table below).

The Imax_b current shown in the table is limited by the fuse used (see table Basic electrical and environmental parameters).

The power supply meets the requirement of the regulation of the Minister of the Interior and Administration of 20 June 207 (Journal of Laws, No. 143, item 1002), with the amendment of 27 April 2010 (Journal of Laws, No. 85, item 553).
In addition, the power supply meets the requirements of the Regulation (EU) 305/2011 of the European Parliament and of the Council of 9 March 2011. (CPR – Construction Products Regulation).
Construction and principle of operation of the power supply.
The ZUP-230V-BM power supply includes: the ZUP-BM module, a 24Vdc/230Vac inverter, a 24V battery and a rectifier. The power supply can operate in one of two modes: CSP and UPS. The selected operating mode defines the specific characteristics and behavior of the power supply. This is explained in more detail later in this manual. The ZUP-BM module is responsible for charging the battery and supervising its status, receiving control signals, making decisions on switching the power supply sources and performing functions related to gate control.
With the actual mains supply, the inverter operates all the time, but with no load on its output. This makes it possible to monitor its condition and indicate any damage. In CSP mode, after a mains power failure, the inverter acquires the output power supply and after a set time is switched off to save battery power. When a control signal (fire alarm) occurs, the inverter is switched on and supplies the receivers for a set period, after which it is switched off again.
In UPS mode, after a mains failure, the receivers are switched to inverter power and operate until the battery reaches end-of-discharge voltage, after which the inverter is switched off. In this mode it is also possible to remotely control the switching on and off of the inverter using the DO input. The battery backs up the PSU in case of mains power failure. Its capacity depends on the power of the inverter and the number of operated gates.
The 230Vac/24Vdc rectifier charges the battery, keeps the inverter operating with the actual 230V mains supply and allows the power supply of additional receivers connected to the optional 24Vdc output.A simplified diagram of the power supply is shown below.

For the user, there is a fused 230Vac power supply output of the gate OUT and relay indicating outputs GEN FLT and CSO. Via the GEN FLT output (collective fault signal) the power supply indicates:
– 230V mains power failure,
– inverter damage,
– high resistance of the battery circuit,
– low battery voltage,
– configuration error of a control input from CSP,
– rectifier damage,
– temperature probe damage,
– tripping of the EPO input.
Depending on the selected operation mode, the CSO output triggers gate opening or acts as an additional PSU status indication. The power supply has two control signal inputs CIE and DO. Their function depends on the selected operating mode.
The main feature that distinguishes CSP mode from UPS mode is the way the voltage is supplied to the OUT output and the control of the CSO output, as well as the way the signals from the CIE and DO inputs are received. However, in both cases, 230Vac mains voltage is supplied to the OUT output when mains power is present.
Accessory equipment of the ZUP-230V-BM power supply: ZUP-230V-BM-24V – a module enabling to supply external devices which require uninterruptible 24Vdc voltage.
The module includes a connector for mounting on a TS-35 bus together with a fuse. Voltage is supplied from the rectifier and, in the event of a mains power failure, from the battery. Maximum load of this output depends on the particular type of the ZUP-230V-BM power supply and its operation mode (see table of technical data in 1.2 ).
ZUP-TR – programmable relay module enabling additional time functions. The ZUP-TR module contains a relay, designed for mounting on a TS-35 rail, equipped with a potential-free output with a load capacity of 10A/230Vac and 10A/24Vdc, which can be controlled from both 24Vdc and 230Vac. In addition to the relay, additional elements are supplied: connecting cables, connectors, single-circuit connectors, etc.
The relay can be used, for example, to extend the time of switching the power supply from the mains to the battery or vice versa (in this manual it is the T_DLY time) when the power supply unit cooperates with controllers requiring a long break between the power failure and return.
If it is necessary to use this relay, it is required to contact the manufacturer of the power supply in order to agree on detailed electrical and assembly requirements.
2.1. Operation in CSP mode for air gates.
The CSP mode is designed to work with the output of the CIE (Control and Indicating Equipment) or the output of its wire module. Receiving a fire alarm signal through the CIE input causes control of the relay at the CSO output, which, through the gate controller, causes opening of the gate. In the event of a mains power failure, the voltage is switched off at the OUT output after a set TS time of the inverter. Only when the control signal appears, it restarts the inverter, which supplies the OUT output and then, with some delay, the relay at the CSO output is controlled The delay enables the operating conditions of the controller to settle down so that the controller can accept this signal. The DO control input functionally works in the same way as the CIE input. The differences concern their purpose and the way they are connected. The CIE input is designed to work with CIE and the way it is connected can be configured. The DO input only enables to connect an additional manual push button to open the gate by closing its terminals.
The DO input should not be used for normal daily gate operation. In the absence of mains power, this can lead to discharging of the batteries and incorrect operation of the PSU in the event of a real emergency. The manual gate opener button connected to this output should be treated in the same way as the fire alarm buttons, i.e. it should be protected against accidental or unauthorised use. Restoration to normal operation requires it to be reset and re-secured. If the DO input is left in the ON (closed) state, in any situation where the CSO signal has already been switched off, the appearance of a fire alarm at the CIE input switches it on again
Note.
For the factory settings, voltage is always present at the OUT output when mains power is present.
In the absence of mains power, battery operation lasts only a specified time. For more information on the electrical parameters for the CSP mode, please refer to the technical data table in 1.2. The time dependencies for this mode are presented in 3.1

DO – Manual opening of the gate. Digital input active by closing the terminals.
CIE – signal input from CIE or wire module output. It can be configured as a digital input with wire resistance monitoring. For digital inputs it will be respectively closing and opening of the terminals and for operation with wire control, low and high resistance (see Power supply configuration). CSO – relay output. In CSP mode, the CSO output is responsible for triggering the gate opening by closing the corresponding input in the gate controller. Continuous or cyclic operation can be set, with repeated pulses triggering the gate opening. The function of this output can also be changed to indication of 230V mains power failure.
EXT MOD – connector for connection of expansion modules.
2.2. Operation in UPS mode.
The UPS mode only provides voltage backup to the OUT output after a mains power failure (see 3.2). The backup time is limited only by the capacity of the batteries used and the actual load. In this mode, the inverter operation is controlled by the DO input. Through this input, the inverter can be remotely switched off and on again. The CIE input is inactive in this mode of operation. For more information on the time dependencies for UPS mode, see 3.2 and 5.8.

DO – Signal of resuming or shortening the operation time. Digital input active by closing the terminals.
CSO – relay output. In UPS mode, the CSO output is responsible for indication of low battery voltage. This function can be changed to indication of 230V mains power failure.
2.3. EPO circuit breaker
An EPO (Emergency Power OFF) circuit breaker can be connected to the power supply.
Note.
The EPO circuit breaker may only be used when operating in UPS mode. Operation of the power supply in the CSP mode, i.e. as a fire protection device, excludes such a possibility.
Its use causes a complete shutdown of the power supply: disconnection of the 230V output and the 230V mains supply as well as disconnection of the internal inverter from the battery. The disconnection concerns only the L wire of the 230V supply system. The N wire between the mains input and the PSU output remains connected. In this state only the power supply controller and its status indication remain active.
The purpose of the mains disconnection relay is to protect against backfeed -. voltage appearing in the mains circuit as a result of the operation of the inverter in the power supply.
The power supply enables selection of the operation mode of the EPO signal input: by opening or closing the terminals – see pos. 9 in the table describing the setting of the slide switch in 5.8. Restoring the power supply to operation, apart from switching off the EPO signal, requires a reset of the power supply with the RUN button. If this input is not used, the terminals of this input must be necessarily closed and the slider no. 9 of the SETTINGS switch set to the ON position.
Detailed description of the power supply operation
A table of detailed setting ranges for CSP and UPS mode is provided in 5.8. A description of the time designations used in Figures 5 to 13, together with their values, is presented in the table below.

duration)
T CSO| 2s/12s| gate opening delay

Each switching of the power source is associated with a loss of the output voltage for the T_DLY time. There is a choice of two values for this time: 2s or 25ms.
Switching from battery to mains supply can only take place when the 230V mains voltage has been present and stable for the T_MR time (5s). This function protects the power supply against the connection of unstable mains voltage.
The presence of a control signal at the CIE or DO inputs for a minimum of 2s (T_CIE time) is required to eliminate false alarms and disturbances. A too short or unstable signal will be ignored.
There are two values of gate opening delay time to choose from: 2s or 12s.
3.1. CSP mode
The voltage at the OUT output when the mains supply is present is always present. The inverter operates during this time for control purposes only. In the event of a mains power failure, the voltage is switched off at the OUT output after a set TS time of the inverter. Giving a control signal to the CIE or DO input (they have the same function) activates the power supply for TA time (9min), during which the inverter supplies the OUT output. The CIE input is dedicated to operate the fire automation signal, hence it can be supervised, the DO input is dedicated to connect a manual gate opener button.
The figures below present basic situations of the power supply operation in the CSP mode, in which the voltage backup at the OUT output has been set to continue with the present mains supply, in spite of the termination of a fire alarm (the H sliding switch in the ON position, see the table in 4.).
Setting the switch to OFF position will switch off the voltage at OUT output after TA time (simultaneously with CSO signal disappearance) both in case of the present mains supply and battery operation. This is intended to improve safety during firefighting operations. Thus, the occurrence of a fire alarm will trigger a certain action of the power supply only once. A second or subsequent alarm signal will have no effect. Return to normal operation after the abovementioned action and restoration of the voltage at the OUT output requires a reset of the power supply by pressing the RUN button (see the table in 4.0.).  The CSO output can operate in two ways (see table in 4.0.): − give a continuous gate-opening signal; − cyclically repeat the pulses that trigger the opening of the gate. The second way can be used by some gate controllers to automatically resume its movement if the gate is temporarily mechanically blocked, or stopped by a button on the control panel.
Fig.5 (below) Return of mains power and appearance of fire alarm with 230V mains power present.

In the stand-by state ( without fire alarm) the appearance and then the persistence of a stable MAINS supply for a T_MR time causes the power supply to switch to the OUT output. If a signal appears on the CIE input at the present mains supply and is  aintained for the T_CIE time, a countdown of the TA and T_CSO times will be started. After the countdown of T_CSO time, the CSO relay is excited, triggering the opening of the gate. With the end of the TA time countdown, the CSO relays switched off.
Fig.6 (below) 230V mains power failure and appearance of a fire alarm in the absence of mains power.

In the event of a mains power failure, a switchover to battery power takes place after T_DLY time for a set TS time. If there is a signal on the CIE or DO input present for a T_CIE time, the inverter is activated. After T_INV time (time required for inverter start-up), the voltage at the inverter output appears and the countdown of TA and T_CSO times starts. After the countdown of T_CSO time, the CSO relay is excited, triggering the opening of the gate. Then, after the TA time has passed, the inverter and the CSO relay are switched off.
Fig.7 (below) Appearance of a fire alarm during battery operation caused by 230V mains power failure.

The detection of a fire alarm at the CIE input during battery operation (triggered as in the description to Fig.6.) causes the interruption of the TS time countdown and the start of the TA and T_CSO time countdown. Then, as before, after the countdown of theT_CSO time, the CSO relay is excited, triggering the opening of the gate. Then, after the TA time has passed, the inverter and the CSO relay are switched off.
Fig.8 (below) 230V mains power failure during theTA operation triggered by a fire alarm.

230V mains power failure during TA time countdown forces switching to battery supply with momentary power failure at theT_DLY time. The behaviour of the CSO relay, previously switched on after recognition of the CIE signal, depends on the setting of the T_DLY time (switching time of the power source). For a set long break time (2s), the CSO relay is switched off together with the mains power failure and switched on again, after switching to battery operation, with the T_CSO delay. This behaviour is compatible
with the gate controllers, which do not tolerate even short power outages, after which they need to be reset and restarted – to continue opening the gate.
Gate controllers that are able to ignore the short break time (25ms) do not require a reset and restart operation. In this case switching on of the CSO relay is maintained despite a change of the power source.Fig.9 (below) Return of 230V mains supply during battery operation caused by mains power failure.

Detection of MAINS stable mains supply at T_MR time interrupts the TS time countdown (see description to Fig.6.), ends battery operation and with a delay of T_DLY restores mains supply to the OUT output.
Fig. 10a. (below) Return of 230V mains supply during battery operation triggered by a fire alarm, with interruption of battery operation.

If battery operation is allowed to be interrupted when the mains supply returns (see 4. Description of ZUP_BM board, switch B), switching to mains supply takes place as soon as the stable mains is detected at the T_MR time. In this case, after the TA time is counted down, only the CSO relay is switched off. The detailed way of switching to the mains power supply including the operation of the CSO relay is included in the description to Fig.8.
Fig. 10b (below) Return of 230V mains supply during battery operation triggered by a fire alarm, without interruption of battery operation.

If the possibility of interruption of battery operation on return of the mains voltage is disabled (see 4. Description of ZUP_BM board, switch B), in spite of its return in TA time, the switching to the mains voltage takes place as soon as this time has passed, provided that the mains voltage was sustained before that time longer than the T_MR time and additionally only after the T_DLY break time. The CSO relay is switched off at the end of the TA time countdown.
If, however, the battery is discharged during battery operation, the switchover to mains operation will take place immediately, as indicated in the description to Fig.10.a above.
3.2. UPS mode
In this state, the voltage on the OUT output is always present when the 230V network is present. The CIE input is inactive.
The way the device operates depends on the setting of the switch no. 4 in the CI section defining the operation of the DO input (see 5.8 Power supply configuration). For battery triggered operation (switch in OFF position) it is recommended to use a monostable switch (e.g. a button). A bistable switch should be used for battery static operation (switch in ON position).
For slider switch no. 4 set to OFF (triggered switchable battery operation), a switchover to battery operation takes place as soon as a mains power failure is detected. At the OUT output after the
T_DLY time a voltage of 230V from the inverter appears. In this state, appearance of a low state at the DO input causes switching off of the inverter (230V voltage failure at the OUT output). Each reappearance of the low state on the control input changes the operating status of the inverter – it turns it on if it was previously off, or turns it off if it was previously on. With the mains supply present, the DO input is inactive.

In case of the slide switch no. 4 set in the ON position (static battery operation, switched on) at the moment of detecting the mains power failure, the battery operation is switched (switching of the OUT output to 230V voltage from the inverter after the T_DLY time) provided that the DO signal is active. This voltage is maintained as long as the signal at the DO input is active. When no active signal is detected at the control input, the inverter operation is switched off. The inverter can be switched on again when an active state is given to the DO input.

The return of a stable voltage from the mains (for the T_MR time) causes the OUT output to switch to the mains regardless of the state of the DO input. If an active state was maintained on the DO input before the mains power returned and the OUT output was connected to the inverter voltage, the output from the inverter will be switched to the mains.

Start-up of the inverter in the absence of mains power and its continued operation depend on the state of charge of the batteries.

Installation

5.1. General notes
The place of installation of the power supply should be selected in such a way as not to expose it to mechanical damage and not to exceed the acceptable parameters of temperature and air humidity. If possible, the power supplies should be installed in fire-separated rooms (e.g. electrical switchboards, technical rooms, cable shafts, etc.). A small cabinet (S type) should be fixed directly to the wall through 3 holes in its back wall, whereas a medium and a large power supply cabinet (types M and L) can be fixed directly to the wall through 4 holes in its back wall or using four distance brackets. The location of the fixing holes is shown in Fig.1. Metal screw anchors should be used for installation. Screw anchors made of PVC must not be used. When assembling a medium or large cabinet with direct use of the rear panel openings, it is advisable to first remove the inverter by unscrewing the two nuts at its bottom, tilting it slightly and sliding it downwards. Due to its weight and dimensions, the battery should be placed in the  abinet  last, after all cable connections have been made.
Note.
The selection of cables in power supply and control systems for fire protection devices should take into account Art. 187 of the Regulation of the Minister of Infrastructure of 12 March 2009 Dz. U. /Journal Of Laws/ No. 56 item 461 on technical conditions to be met by buildings and their location, as amended. Consolidated text of the Ordinance of the Minister of Infrastructure of 7 June 2019 item 1065.
5.2. Connection of mains supply
The mains supply cable with a minimum cross-section of 3×1.5mm 2, after being fixed in the gland, should be led through a large arc before it is fixed by the cable holder and connected to the corresponding terminals of the ZUP power supply. The outer insulation of the cable (tyre) should be removed directly behind the cable clamp.
Note: It is absolutely necessary to identify the L wire of the mains supply and to connect it properly to the L terminal of the ZUP-230V-BM feeder (MAINS 230V connector, L terminal).
The connection of the mains supply must be made as a permanent installation with continuity of the neutral wire (N). The installation switch described below must be in the live wire (L). The power supply is not equipped with its own mains circuit breaker, so a special installation breaker is required outside the power supply. Such a circuit breaker should also perform the role of an overload and short-circuit protection and allow to power devices with a high starting current. It is recommended to use the S301 C16A installation circuit breaker. Such a circuit breaker should be clearly marked as being used in the fire protection system and must not be used in other circuits at the same time.
Warning.
Connecting the mains using the switch located outside the power supply can be done only with fully assembled internal wiring of the power supply, including the inverter correctly connected and mounted. It is forbidden to leave the 230Vac power plug disconnected from the inverter output.
5.3. Connection of 230Vac circuits
The wires for external connections should be routed through the selected openings in the cabinet body (after removing the blanking plugs) and fixed by twisting the appropriate cable glands. The wires which are to be led to the output (and outputs of optional expansion modules) after fixing them in the glands should be led through a large arc before they are fixed by cable holders and connected to respective terminals of the ZUP power supply. The outer insulation of the cable (tyre) should be removed directly behind the cable clamp. A 3-core HDGs 1.5mm 2 cable is recommended for making connections of 230Vac power supply systems in fire protection systems. For devices of insulation class II, it is possible to use 2-core cables without connection to PE bus. Only one consumer device can be connected to the OUT output on the ZUP-BM board of the power supply. It is necessary to pay attention to the nature of load carried by some receivers. For example, induction motors can consume considerable current at start-up that can lead to blowing of the fuse placed at the given output or prevent correct start-up of the inverter.
5.4. Connecting the battery
The battery, placed with its terminals on the door side of the housing, must be connected using the two wires already brought out from the power supply, paying particular attention to the correct polarity: red wire to the positive terminal of one battery, black wire to the negative of the other battery. Finally, connect the two batteries to each other using the cable (connector) supplied by the manufacturer.
NOTE: The power supply is not protected against reverse connection of the battery. Incorrect connection may lead to destruction of the power supply.
The battery should be connected with the battery disconnector switched off and its fuse link removed. All connections should be made carefully, bearing in mind that during battery operation (when the mains supply is off) the current drawn by the inverter may reach 90A. For correct temperature compensation of the battery floating operation voltage, the temperature probe should be placed between the sides of both batteries.
5.5. Emergency operation with one power source.
The power supply should work with both power sources connected:
– primary, mains;
– backup, battery.
However, it is possible to run the power supply in an emergency when only one power source is present, which will, for example, allow the gate to be operated, but will not ensure that the primary function -of providing a guaranteed power supply is fulfilled.
Below, there is an indication of the operational status of the ZUP-230V-BM power supply in case of connection of both power sources (mains and batteries) or only one of them. Start-up of the power supply from the mains is automatic. In case of lack of the mains power supply, the RUN button should be pressed (see 4).
The table shows the operation of the power supply in the CSP mode. Notes under the table indicate differences specific to UPS mode.

*) The indicated LED state corresponds to the absence of an active state at the CIE input. Its short flashes additionally indicate the correct state of the CIE wire (see table in 4.). In UPS mode, the CIE input activity indication is off.
) In UPS mode with switch operation, the DO input activity indication lights up. In this mode, with battery power only, the OUT output is supplied with voltage from the inverter, so the OUT LED lights up yellow.
Yellow LEDs are mounted near the bottom edge of the housing of both indicating relays. Their lighting indicates the state of excitation of the respective relay.
5.6. Connection of control inputs.
** The CIE input (confirming the fire alarm signal from the CIE) can operate with parameterisation  or as a binary input. However, in both cases it is required that the parameters of the control circuit are within certain defined limits: − for input with parameterisation, resistance values including connection resistance and leakage resistance (between wires) must not differ by more than 10% from the required value of 1kΩ and 10kΩ
− for binary input the short circuit resistance must not be higher than 1kΩ and the leakage resistance (between wires) must not be lower than 100kΩ.
If these values are exceeded, the power supply sets the GEN FLT error indication.
The DO and EPO inputs, unlike the CIE input, are not supervised. They are binary inputs responding to short-circuit and open terminals.

5.7. First start-up.
5.7.1. Starting the power supply in the CSP mode.
The power supply start-up process described below refers to start-up using the factory settings described in 5.8. It is recommended that the first start- up be performed by service personnel trained by the manufacturer. In case of a different PSU configuration than the one resulting from the factory settings, some items will look different. The presented process assumes correct operation of all elements. In case of any discrepancies, please refer to the appropriate descriptions included in the operational manual or contact the manufacturer’s service to clarify any doubts.
Initial state:
− mains power disconnected by the installation switch (outside the power supply);
− terminals of the batteries are not connected and, additionally, the batteries are disconnected by the circuit breaker inside the power supply (marking on the diagram: W-BAT)
− if no gate controller is connected to the OUT output, any receiving device (voltage indicator, bulb, motor, etc.) should be connected in its place;
− if no gate controller is connected to the CSO output, e.g. an ohmmeter or other tester will be needed to check the relay status on this output;
− if no receiver for this signal is connected to the GEN FLT output (e.g. fire panel), e.g. an ohmmeter or other tester will be needed to check the relay status on this output;
− check the configuration of the SETTINGS switch, which should be in accordance with the factory settings (see figure below);

The setting of the Ah section (sliders 5 and 6) should correspond to the specific type of power supply being activated, and the battery used (see tables in 5.8.)
− resistors parameterising this wire should be connected to the CIE input as shown in Fig. 15. with the 1kΩ resistor circuit being open (no fire alarm);
− the DO input should be left unconnected and, if it is to be used, the switch connected to it should be opened (no forced opening of the gate);
− a jumper should be placed on the EPO input (this input is not used in CSP mode).
Preparation for start-up:
− connect the battery terminals paying special attention to the correct polarity (reversed polarity can lead to permanent damage to the power supply;
− Switch on the W-BAT battery switch.
Start-up

1. Switching on the mains supply
   • the green ON diode lights up permanently (power supply operation indication);
   • a test of 5 LEDs is carried out, the LEDs light up one after the other and then go out, leaving the current operating status indication:• short flashes of the CIE diode indicate correct operation of the CIE fire alarm wire parameterisation system;
   • green colour of the OUT LED indicates presence of the mains power at the OUT output of the power supply.Relay outputs: GEN FLT excited (no damage) CSO not excited (no signal to open the gate)

2. Switching off mains power (switching to battery operation)
   • the power supply switches to backup source (battery), which is indicated by the OUT diode turning yellow as soon as voltage from the inverter appears at the OUT output;
   • after a short power failure, for the T_DLY time of 2s, the voltage from the inverter appears at the OUT output which is independently maintained in this state for the maximum TS time of 9min.Relay outputs:
   GEN FLT not excited (fault indication – no power supply) CSO not excited (no signal to open the gate)

3. Transmission of a fire alarm signal to the CIE input.
   • at TS time, when battery operation is in progress, connect a 1kΩ resistor to the CIE input for longer than T_CIE 2s;
   • from this moment on, at the OUT output supplied by the inverter, the voltage is maintained independently for a maximum TA time of 9min. Relay outputs:
   GEN FLT not excited (fault indication – no power supply)
   CSO excited after T_CSO time of 12s, which triggers opening of thegate (if the gate controller is connected)

4. Return of mains power during gate opening
   • at TA time, during operation triggered by a fire alarm, this alarm must be disabled (disconnect the 1kΩ resistor from the CIE input) and then restore the mains supply; If a gate controller is connected to the power supply, it is advisable to perform this  operation before the gate is fully open.
   • the power supply switches to main power source (mains), which is indicated by the OUT diode turning green as soon as voltage from the mains appears at the OUT output;
   • the inverter enters standby mode which is indicated by its ST-BY LED;• after a short voltage decay, for the T_DLY time of 2s, the mains voltage appears on the OUT output;
   • the relay at the CSO output temporarily, at T_DLY + T_CSO time of 14s stops being excited and after TA time of 9min switches off permanently,
   If a gate controller is connected to the power supply, the return of the CSO signal should resume the gate movement if it has stopped during a temporary mains power failure.
   • after the TA time of 9min has elapsed, the power supply returns to the state described in step 1 of start-up.
   The TA time countdown can be interrupted (shortened) by pressing the RUN button.The time course shows the entire start-up process with an indication of its successive steps.

5.8. Power supply configuration
On the ZUP-BM board there is a slide switch allowing to set the function of the power supply. Some of the settings require restarting the power supply, restarting by temporarily disconnecting the 230V mains and the battery until the ON diode goes out. In the table below, these particular slide switch positions are enclosed in rectangular brackets [ ]. Description of the SETTINGS switch sliders.

Additional information

7.1. Manufacturer’s remarks
The manufacturer reserves the right to introduce design and process modifications not affecting the parameters of the product.
7.2. Compulsory technical inspection
The ZUP-230V-BM power supply should be subjected to periodical technical inspection by the manufacturer’s service or an entity authorised by the manufacturer at least once a year during its entire life.
Any work carried out by unauthorised persons, or failure to carry out periodic inspection, may result in the loss of the manufacturer’s warranty and will transfer the responsibility for the correct operation of the power supply to the user. The execution of the inspection should be confirmed by an appropriate protocol according to a model established by the manufacturer.
The user is obliged to ensure access to the devices to be inspected and to present documentation showing how the power supply is connected to the cooperating devices. It is recommended that such documentation, operational manuals for the power supply and associated equipment and inspection records are kept together and made available upon request by the manufacturer and during periodic inspection. It is also recommended that between inspections, during normal operation of the equipment, attention be paid to any electrical or mechanical damage, both to the power supply itself and to the associated equipment, which could affect the operation of the entire assembly. Any observations or concerns arising from this should be reported to the manufacturer for assessment of their potential impact on further operation.
Technical and service issues, as well as those related to periodic inspections, please contact directly the MERAWEX Service Department or a unit authorised by the manufacturer.
Note
The obligation to carry out regular technical inspections of fire protection equipment results from the ordinance of the Ministry of Internal Affairs and Administration of 7.06.2010 on the fire protection of buildings, other civil structures and areas (Dz.
