6 Current requirements
6 Current requirements
The FSZ Pro provides a total output current of 900 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 900 mA. The current consumption of the various components of
the hold-open system is specified in the related product documents.
6.1 Energy storage module ESM Pro
(must be ordered separately)
6.1.1 Operating mode – buffering 24 V
The ESM Pro supports two different operating modes, which can be activated or deactivated using
DIP switch 5 (buffering 24 V).
Operation mode buffering 24 V deactivated (see page 22)<GT>
Complete system is buffered for max. three seconds.
Operation mode buffering 24 V activated (see page 23)
Only the 24 V supply voltage is buffered until the energy store is emptied.
