3.12.16 Sounder-Strobe FI750/WBRIS/SOUW – FI750/WBRIS/SSTWCR – FI750/WBRIS/SSTWCW
This sounder or the sounder-strobe is actuated via the parallel output of the detector.
If the devices are connected to Fire Detection Control Panels Series
BC216
, a maximum of 8 sounders
of the stated type can be simultaneously activated per loop, because the number of detector/module
LEDs that can be activated is limited. The parallel output of the actuating element (detector) has to be
set to „contin. on“. The tone is set by means of the switches on the signalling device.
If this alarming device is used on the
BC600
, the parallel output of the detector can be freely parame-
terised according to the requirements. This is done with the RI setting „intelligent“. 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).
On the base sounder or sounder-strobe there is a DIP switch by means of which the tone, the sound
level and the flash energy can be set. The setting is made in the same way, irrespective of whether the
device is used on the BC600 or on the BC216.
