Automatic detectors Series FI750
All automatic detectors are connected in parallel to the loop. Alarm resistors or end-of-line resistors are
not needed. All Series FI750 detectors are provided with a dual-isolator which interrupts the loop in the
event of a short circuit, thereby ensuring the functioning of the remaining elements.
The following automatic detectors Series FI750 can also be connected to a loop with the Labor
Strauss/700 protocol:

3.5.3.1 Programming the address of automatic detectors
How the address is set is described from page 95 onwards in Chapter 3.3: „Address programming of
loop elements“.
3.5.3.2 Connection of Detector Bases FI750/B
All Series FI750 detectors can be inserted in the following detector base:

Detector Base
FI750/B
If the remote indicators are connected to Fire Detection Control Panels Series
BC216,
a maximum of
8 remote indicators can be simultaneously activated per loop, because the number of detector/module
LEDs that can be activated is limited.
If the remote indicator is used on the
BC600,
the parallel output of the detector can be freely paramet-
erised according to the requirements. This is done with the RI setting „individual“. In this case the
limitation of 8 detector/module LEDs that can be activated is cancelled for this output. Therefore it is
all the more important to check the maximum number of sounders by means of the loop calculator
spreadsheet FireSysCALC_xxx.ods (available in the download area of the LST website – registration
required).
