3.12.14 Sounder-Strobe FI750/WBRI/MT/SOUW – FI750/WBRI/MT/SSTWC
This sounder or the sounder-strobe is actuated via the parallel output of the detector and is activated in
the alarm condition 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“.
If this alarming device 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).
3.12.14.1 Connection
The switches by means of which the tone and the sound level are set, are located on the bottom of the
base. That is why the setting of the switches at the time of shipment is printed on a label. If you
change the settings, you can write the new settings on the label for documentation purposes.
3.12.14.2 Tone setting
On the base sounder there are switches by means of which the sound level and the tone can be set.
Three tones are listed here as examples.
