Fdnet Extinguishing Interface; Close-And-Retain Systems (Fsa) - Siemens SIGMASYS C Manual

9.1.4

FDnet extinguishing interface

The FDnet extinguishing interface comprises the following modules:
one FDCIO224
one All-or-nothing relay
one SMxx extinguishing interface
one PC board block 32-pin
The all-or-nothing relay and the FDCIO224 are mounted on one top hat rail.
The SMxx extinguishing interface can be plugged in directly to the X100 basic module.
For the actuation of other extinguishing control modules, the SMxx extinguishing interface is
plugged into the 32-pin PC board block.

Close-and-retain systems (FSA)

Device for closing fire protection traps (doors, openings for conveyors) in a fire section.
Under normal circumstances, the fire section doors are held open by the FSA. In the event of
an alarm or a detector fault in the relevant fire section, the doors are automatically closed by
the FSA. The locking device is a GMA element with its own power supply unit. It is activated
by the GMA. It must be ensured that the locking device operates even if the detectors as-
signed to the fire section fail in order to protect the fire section. Possible faults are, for exam-
ple, a failure or deactivation of the MPL, failure of the control and indicating panel, mains
power failure, etc.
In accordance with DIBt (German institute for structural engineering), detectors should be
provided for and specially dedicated to FSA. Subject to approval, the smoke detectors may
control the FSA.
For the FSA control, a control output is programmed with SIGMAPLAN at the next
SIGMALOOP- or Sinteso detector output. This is connected via the control module SPF 5100.
The detector output is activated if the associated detector zone(s) is(are) idle.
The control output is reset in the case of:
alarm
fault detector
fault detector zone
fault loop
disablement detector zone
inspection (as long as the detector is in inspection alarm)
