Product Description
3.13. Application
ZUP/ZUP-L modular power supply is designed for supplying low and ultra-low voltages
(max: 1000 V AC, 1500 V DC) to the smoke and heat control systems, including the power
supply of the smoke exhaust and makeup air fans, using frequency converters.
The power supply is also suitable for such equipment items as fire dampers (including
fire ventilation dampers), smoke exhaust windows, smoke dampers, solenoid valves,
electromagnetic door holders and gates.
The product successfully passed the functional tests and evaluation of performance
parameters and has been granted the approval for using in fire protection systems by the
Scientific and Research Centre for Fire Protection –National Research Institute in Józefów.
The difference between ZUP and ZUP-L:
The ZUP-L type power supply is not equipped with Automatic Reserve Switching (SZR).
3.13. Basis for the Study
The subject-matter of this study is an idea of a A class, UZS modular power supply for
energy distribution of low and ultra-low voltages in smoke and heat control systems (series of
PN-EN 12101 and PN-EN 54-4 standards).
The appliance has been created in order to meet the formal requirements for placing on
the market systems of supplying certified devices by uncertified components (e.g. inverters,
contactors, relays), for which there is no legal basis for evaluation according to I conformity
evaluation system and for proving the reliability of such solutions.
This study is based on the provisions of PN-EN 12101, Part 10: “Power supplies”.
It contains the following part:
(…)
“A power supply for smoke and heat control systems can be intended for supplying
pneumatic systems, low voltage and ultra-low voltage electrical systems, and any combination
of the above.
The power supply units for smoke and heat control systems can supply energy necessary
for everyday ventilation of rooms and for supplying other fire protection devices operating
under fire conditions”.
According to Annex A to the above standard, low voltage is the voltage up to 1500 V DC
and 1000 V AC. Ultra-low voltage is the voltage up to 75 V DC and 50 V AC.
ZUP power supply unit meets the requirements of PN-EN 12101, Part 10 and PN-
EN 54-4 standards.

3.13. Operating principle
The ZUP power supply unit may be used for supplying the components both of fire safety
and household ventilation systems.
The power supply unit is adapted to work with control signals by potential-free contacts.
After receiving a signal, the relevant constituent module of the power supply switches on/off
the power supply to a given consumer unit. If the consumer equipment is used in non-fire
mode, it can be controlled by any control system (it is possible to install its components inside
the ZUP housing). In the fire mode (master) for equipment connected to the power supply
unit, the control signals are sent from the Control Panels or their modules. The control panels
need to meet the requirements for fire and non-fire control.
When activated, the power supply continuously monitors the parameters of the mains
and feeding lines to the respective components of the fire safety system. If any irregularities
are detected, a generic failure signal is sent, and the corresponding LED starts to glow on the
power supply’s housing.
The power supply enables the Control Panel to monitor power transmission paths to the
supplied fire safety components by using line control modules embedded in the power supply.
The “Żubr” series power supply unit also fully controls activation of the respective modules by
external monitoring units (it is possible to install them inside the ZUP housing).
Constituent modules
The power supplies are manufactured as integrated units provided with a specific number
of component modules. The modular design makes it possible to adapt the device functionalities
to individual demands, in terms of both the number of supplying devices and their types.
The description of modules presented below is optional and depends on the technical
conditions at the installation site and the intended function of the unit assumed by the designer
of the system supplied.
The mutual relations between modules result from the intended functionalities of the
device and are subject to individual electrical design of each of the ZUP power supply unit
pieces.
4.1. MZR Module - Reserve Activation Module
The reserve activation module is used for automatic switching between separate sources
of electric energy (primary and backup) with the use of the Automatic Reserve Switching (MZR)
system. In the event of the loss of the primary power source, the MZR automatically switches
the power supply line to the backup power supply and signals the loss of the primary power
supply. When primary power is restored, the MZR switches back to primary power supply.

4.13. MZ24 Module –24 V DC Power Supply Module
24 V DC power supplying is carried out by the power supply unit adjusted for
cooperating with batteries, which meets the requirements of PN-EN 12101-10 for signalling
systems and firefighting automation.
24 V DC power supply unit is available in various power variants, depending on expected
load (output current –from 5,5 A to 50 A).
The MZ24 power supply module is equipped with a battery backup system. The
batteries are selected so that their capacity meets assumptions of Item 6.2 of the standard.
They are charged and monitored by the power supply unit. In case the discharge state or
damage of batteries has been detected, the power supply unit reports an error to the Control
Panel.

4.13. MZSW Module –Power Supply Unit for Fire Safety Fan Motors
A single module consists of the protection circuit of the energy receiver and the final
control element of the electrical connection. The protection circuit of the fan motors consists
of self-acting motor switches (e.g. PKZM0 or NZMH2 type) with adjustable actuation set
points. The protection circuit of the frequency converter consists of thermal fuses (e.g. FWC
type). Power contactors (e.g. DILM) or MCD201 and MCD500 Danfoss soft starters, or FC101
and FC102 Danfoss frequency converters serve as connecting elements in the power circuit.
The devices included in the modules are additionally equipped with ancillary contacts
making it possible to monitor their present state (whether they have acted or not).
The frequency converter can have braking resistors attached in case when it supplies
fans working with quick-change rotation. The converter is able to receive voltage signals
within the range from 0 to 10 V DC, determining set rpm of the powered motor.

For starting motors of higher power, star–delta changeover switches consisting of
contactors (e.g. DILM) and time relays are used.
Depending on the power of the fan and its operating mode, the following modules,
performing tasks listed below, may be applied:
•Direct activation (up to 5.5 kW)–MZSW-ZB
•Activation through a star-delta system (from 7.5 kW to 75 kW)–MZSW-GT
•Activation of first/second gear of the fan (Dahlander system)–MZSW-2B
•Activation in any direction –MZSW-2K
•Activation of first/second gear of the fan (Dahlander system)in any
direction - MZSW-2B2K
•Activation and supplying through a frequency converter –MZSW-FC
Besides the distribution of electrical power needed for operation of the fans, the
modules also monitor the operation status and possible failures of the power circuit.
Operation confirmation and generic failure signals are transferred to the Control Panel.

4.13. MZKDC Module –Power Supply Unit for Components of the Smoke and
Heat Control System
These modules will provide guaranteed power supply for components of the systems
described in PN-EN 12101-12. The supply lines of these devices are monitored for short and
open circuit. The protection circuits of the powered devices may also be monitored. The line
damage or protection activation signals are transferred to the Control Panel.
The modules are equipped with protection circuits selected for receivers and the supply
line so that the fire protection conditions and the requirement of selectiveness of activation
are met. Depending on the type and power of the receiver, the overcurrent protection or fuses
with proper characteristics are used.

4.13. MZKP Module –Power Supply Unit for Fire Damper Actuators
These modules make it possible to supply the actuator or group of actuators of fire
dampers (with transition to the fire position once the power supply failure occurs) and the fire
ventilation (controlling supply changeover between the actuator contacts).
The position of the damper baffle is controlled in two positions –open and closed.
Additionally, the Control Panel is capable of supervising the correctness of the damper
operation by monitoring the time of change of the baffle position.
The supply outputs are protected with proper fuses which are monitored by the Control
Panel.
The connecting and switching functions in the power circuit are performed by relays
with monostable changeover contacts (NO and NC), e.g. RM84 or R4 type.

4.13. MKL Module –Supply Line Control Module
This module makes it possible to detect the damage in power cables for peripheral
actuators (e.g. fan motors, fire damper actuators). The MKL module makes the Control Panel
capable of continuously supervising the status of the system supplying energy receivers.
3.8.1 MKL N-780
The N-780 Line Control Module makes it possible to detect open and short circuits in the
fans power and control circuit along with the supervision of the motor winding. Due to the
use of MKL N-780 it is possible to monitor the service (repair) switch applied in the fan
wirelessly. Disconnecting the fan power and control circuit by the service switch is detected
by the MKL N-780 module as an open transmission circuit which triggers the alarm. Thanks
to this functionality, the cost of the service switch alone is reduced (no need for extending
the circuit with additional position monitoring contacts) and the cost of the additional cable
for monitoring the service switch position contact is completely eliminated.
With the use of MKL N780 it is possible to monitor power cables for fan motors in the
following configurations:
•two fans with direct start-up (star or delta)
•two fans supplied and controlled by frequency inverters
•single fan with a star-delta start-up
•single two-speed and/or two-way Dahlander fan
Connecting the Module:

Connect 24 V and 230 V AC power supply.
The green D1 LED should indicate the activation of the system.
Connect all motor windings according to the markings.
In order to start the measurement apply 24 V voltage to the “contactor” input.
By pressing and holding the S1 button for about 3 seconds, the system memorizes the
parameters of the windings of the engine being in good working order. It is the so-called
“teaching process”, indicated by the yellow D2 LED flashing. Once the process is
successfully completed, this LED stops flashing and starts to light continuously.
Henceforth the system begins to analyse the status of the power supply and control
transmission circuit for the motor along with its windings. In case of open or short circuit
in the power supply circuit or motor winding, the module indicates this state by the red D3
LED flashing.
In order to shut the motor down disconnect the “contactor” input beforehand. Otherwise
the system will suffer damage.
The S2 switch is used for selecting the module operating mode. When the switch is in
position No. 1, the module is adapted for examining a single motor with 6 cables, whereas
in position No. 0 the module works with two motors with 3 cables each.
