6.1.1 Detector lines
Detector lines 1, 2 and 3
The fire detector of detector lines 1 and 2 are used for automatic activation.
The fire detectors of detector line 3 are intended for monitoring of the surrounding
areas. They can be used, if required, for automatic extinguishing.
Connectable detector types:
–
Conventional detectors without "Siemens" current limiting
–
Conventional "Synova" detectors with current limiting
For configuration of the type selection, see chapter 5.3.1.
Linking detector lines 1, 2 and 3
In the default setting of the control unit, the fire detectors of zones 1 and 2 monitor
the extinguishing area and are wired in cross-zoning and fire detectors in zone 3
monitor the area outside the extinguishing area.
–
One detector in zone 1 or 2 triggers a fire alarm.
–
One detector in each of zones 1 and 2 trigger the activated condition.

Fig. 22 Detector lines (zones) 1 to 3, programming step 11
In programming step 11, you can select the following functions:
–
Option 1: "Alarm" zone 1 and zone 2 trigger the "Activated" condition and
"Alarm" zone 1 or zone 2 triggers "Fire alarm"
–
Option 2: "Alarm" zone 1 triggers "Fire alarm"
"Alarm" zone 2 triggers the "Activated" condition
–
Option 3: Same as option 2 but functions "Enable/Disable Zones" and
"Enable/Disable Detector test" suppressed
–
Option 4: "Alarm" zone 1 or zone 2 triggers "Activated" condition
–
Option 5: Zone 1 and zone 2 are not used
–
Option 9: On "Alarm" zone 3, fire controls, RT-alarm, fire alarm (LED6) horn
lines and fire alarm outputs activated
–
Option 10: On "Alarm" zone 3, fire alarm (LED6), horn lines activated
–
Option 11: Zone 3 is not used
