DESIGN AND OPERATING PRINCIPLE
__________________________________
The mcr OMEGA pro Power and Control Panel is intended for control of fire protection equipment
operated in heat and smoke control systems and comprises the following components:
1) An IP54 or IP55 metal enclosure with an operating status LED indicator panel and a mounting plate.
2) A mains power supply unit and surge protection units (optional).
3) Dedicated microchip-based MMS monitoring and control modules.
4) The mcr OMEGA pro Power Supply Unit, which may contain the following, depending on the actual
version:
a. A 24 VDC power adapter for microchip systems and fire protection devices;
b. Contactors or contactor arrays for starting and powering of system fans as follows: direct on line
(DOL), star-delta, Dahlander connections, and fan reversing in all of mentioned;
c. Softstarters: provide power and soft starting of high-power fans;
d. Inverters: for systems with variable or multi-speed motor control. The inverter control is based either
on 0
–10 V, 4–20 mA, or dry contact switching;
e. An Automatic Transfer Switching Modulehin, which can switch the powered loads to an emergency
power generator or a secondary power mains line (optional);
f. Eletrical protections for connected devices;
g. 24 VDC/230 VAC power inverter (optional);
5) Supply line continuity monitoring modules (optional).
6) Fire detection module (optional).
7) Gas extinguishing module (optional).
The operating principle of the actual product will depend on the requirements of the building and the system
the Power and Control Panel is to be installed in and operated with. The Power and Control Panel
operating logic algorithm is customized per the specification data and fire scenario requirements provided
by the installation designer. The panel is delivered to the customer complete with the installation diagrams,
operating logic algorithm specification and specification of components.
Optional functions available with the Power and Control Panel:
Actuators immobilized control;
Alarm status outputs;
Internal operation delay;
Multiple alarm signals processing;
Outputs to other systems not related to heat and smoke control;
Alarm status output;
Fault status output;
Test status;
Test status output.

ENCLOSURE
The mcr OMEGA pro Power and Control Panel is housed in free-standing or wall-mounted metal
enclosures sized to easily accommodate the specified internal components. Depending on the product
version, the enclosure protection rating is IP54 or IP55. The Power and Control Panel form factor will
depend on the complexity of operations and the switching algorithm. An enclosure can be formed by a
single-chamber box or a number of permanently bound, non-distributed modules. The mcr OMEGA pro
Power and Control Panel is rated for Environment Class III and an operating temperature range from -
25°C to +75°C. The enclosure performance and high corrosion resistance permit outdoor installation at
locations directly exposed to weather. For outdoor installations, the enclosure is fitted with a rain canopy
to prevent direct rainfall onto the device. The device may also feature ambient operating temperature
controls, including a thermostat-controlled radiator heater to prevent low enclosure and internal
temperatures, freezing of rain or melt water, and condensation and freezing of air humidity. An integrated
air fan provides forced internal ventilation of the enclosure to control the ambient operating conditions at
high external temperatures and keep the enclosure and internal components cooler.
