12 Monitored lines
Threshold detector technology
Threshold detectors can be connected via transponders to SIGMASYS monitored alarm lines.
If automatic threshold detectors which receive their power from the monitored alarm line are
connected to the transponder, a “line termination for transponder and 4 STE control module”
S24218-C44-A10 is to be connected at the last detector instead of the moving load.
As of Version 2.6, threshold detectors can be connected directly to the GMG-S module in
SIGMASYS M/L control and indicating panels.
12.1 GMG-S module
(as of version 2.6)
Features of the GMG-S module:
• 8 MPLs
– each with up to 30 detectors in the alarm transmission systems MS6/7/9 and
SIGMACON
– Connection from Sinteso FDxxxx-9 detectors (Termination resistor 3k3)
– Ex-line connection (see “Fire alarm signaling in explosion-hazard areas” A24205-
A331-A292)
• 1 FSA output (not for systems with DIBt approval [German Institute for Structural Engi-
neering])
– floating relay contact (for connection of an FSA control module)
– activated in the event of a module fault (if the watchdog expires or if the power fails
and if an alarmin an FSA detector zone is tripped, in the event of a fault or disable-
ment of the FSA detector zone,if there is communication interference at the SOC)
– rating 0.5 A
• Emergency redundancy lines for alarm and fault (via boards)
• 8 DA outputs
– signal form static, also inverse +UB I
max
= 100 mA, I
total
= 500 mA
– freely programmable, activatable system-wide from the SOC
– not monitored for faults or tripping
• Fault detection
– all monitored alarm lines can cause a fault
• ALZ, parameterisable
• Event delay, parameterisable
• Fault delay, parameterisable
• Detector zone formation
– only one detector zone can be assigned per MPL
– cross-module formation not possible
• Detector zone functions (as in SIGMASYS)
