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.
