6 Current requirements
The FSZ Basis provides a total output current of 400 mA. This output current can be completely
used for the required components of the hold-open system. The current required for the hold-open
system consists of the sum total of all currents of the components connected.
Example calculation:
The hold-open system comprises the following components:
Smoke switch 3 x ORS 142 3 x 22 mA 66 mA
Electromagnetic door
retainer 2 x THM 425 2 x 63 mA 126 mA
Total current requirements 192 mA
The total current must not exceed 400 mA. The current consumption of the various components of
the hold-open system is specified in the related product documents.
