Sigmaloop Extinguishing Interface; Table 22: Sigmaloop Extinguishing Interface-Overview Of The Features - Siemens SIGMASYS C Manual

9 Special control facilities
•
The reversing electromagnetic valve is also activated in the event of an alarm
•
The control facilities described above must not be driven by the door contact
•
Control via fault in the power supply unit of the fire alarm control and indicating panel.
Controlling the reversing electromagnetic valve:
Control via SIGMALOOP extinguishing interface.
All detector zones that control asprinkler system must be assigned adetector type with
the following properties:
Check "ST even when door open" under "Set detector zone type" and "Control"

SIGMALOOP extinguishing interface

The SIGMALOOP extinguishing interface consists of several SPF5200 control modules and
two SPF5300 contact couplers as well as a special regenerative coupling unit to avoid inad-
vertent tripping and LOOP monitoring on a module which can be installed in the "32-pole
plug-in card block".It can b eused as the VdS extinguishing interface for all extinguishing func-
tions (water, gas, powder and foam)
Extinguishing control outputs
- Extinguishing command
- Prealarm or revering electromagnetic
valve
- 4 freely programmable outputs for acti-
vating the relays

Table 22: SIGMALOOP extinguishing interface-overview of the features

The SIGMALOOP extinguishing interface can be installed in SIGMASYS C, M, L and D100
control and indicating panels with M modules as VdS interfaces.
The SIGMALOOP extinguishing interface requires three address on SIGMALOOP.
In the X100 extinguishing control the SIGMALOOP extinguishing interface is directly installed
as a VdS extinguishing interface.
Advantages:
Only SIGMALOOP needs to be connected to extinguishing control. All activations and ac-
knowledgements take place via this SIGMALOOP.
The SIGMALOOP extinguishing interface can be implemented universally because all inputs
and outputs can be freely programmed.
7 outputs are provided for activating relays and can be set using a bridge circuit.
8 inputs can be used, as described for the contact coupler.
N.B.: The lines required for the inputs (e.g. fault signal, extinguishing zone)
must not be exceed 40 m in length.
The SIGMALOOP extinguishing interface requires a distribution voltage of 19 to 29 V in ac-
cordance with EN 54-4.
