SzA-FCK - automation cabinet
The SzA-FCK automation cabinet differs from the SzA-FCP automation cabinet in that it
is used for iSWAY-WFC and iSWAY-RFC devices, and additionally it has braking resistors
mounted on the cabinet, covered with perforated sheet metal. It is not mounted inside the unit
(like the SzA-FCP) but directly inside or outside the building.
SzA-FCK has a built-in frequency inverter with fire mode. The cabinet has a built-in MAC-FC
regulator and output circuits - among others, control of the shutter and of the double intake
system. It also provides 24VDC power, with battery backup. Braking resistors are mounted on
the side of the cabinet. The cabinet's power supply is monitored and a power confirmation signal
is displayed on a light on the front panel of the automation cabinet.
Optionally, a P-MAC or P-MACF pressure converter and additional 24VDC outputs (to
TSS, peripheral device) can be installed in the SzA-FCK automation cabinet. Additionally
cabinet can be equipped with a heater.
Cabinets are manufactured in different types depending on the devices mounted inside
the cabinet and the power of the built-in inverter as shown in Table 14.5.

NOTE!
If the "POWER CONTROL" is not signalled, it may mean that one of the fuses is tripped: 1F1, 1F2,
1F3, 1F5, 1F6 in the SzA-FCK cabinet or there is a damage to the power supply circuit of a
frequency inverter (SzA-FCK cabinet - inverter).
