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 acti vation 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.
