9 Electrical installation
2 stubs – DIP 2
DIP switch 2 is only evaluated if DIP switch 1 is set to “ON” at the same time.
The connection of an external manual button is not considered to be a stub.
OFF Only one stub with smoke switches is connected to the FSZ Basis. The termination
module AM 142 (see Fig. 7) resp. a magnet
1)
(see Fig. 8) must be installed in the last
smoke switch (observe chapter 8, section 2 und 3). If no manual button is connected the
termination module AM 142 must be connected to the HAT connection terminal in the
FSZ Basis.
ON Two stubs with smoke switches are connected to the FSZ Basis. The termination module
AM 142 must be installed in the last smoke switch of each of the two stubs (see Fig. 9
also observe chapter 8, section 2 und 3). The total number of smoke switches must not
exceed 9. If no manual button is connected the termination module AM 142 must be
connected to the HAT connection terminal in the FSZ Basis.
1) A magnet can only be used in combination with an ORS 142!
Alarm storage – DIP 3
OFF The FSZ Basis does not store an incoming alarm. If the releasing smoke switch resets
itself or if the manual release button is no longer actuated, the FSZ Basis returns to the
operating state. After a loss of power, the FSZ Basis also returns to the original operat-
ing state provided there is no fault or alarm.
ON The FSZ Basis stores an incoming alarm. This alarm must be reset manually via the inte-
grated or an external reset button.
After a loss of power, the FSZ base returns to the previous operating state after the
voltage is on again. If the previous operating state was an alarm, this alarm is again
signalled. If the previous operating state was a fault or operation, the fault is indicated.
After a power failure, the FSZ Basis must be reset to operate again.
