Class BS applies from firmware version 1.18 on. Thermal detectors with an earlier firmware version comply
with class B and were delivered as type FC650/T/78. The firmware version can be found on the label on the
bottom of the detector.
In the case of the detector FC650/O, the degree of contamination can be read out by means of the Pro-
gramming Unit FI700/PU (or the FI750/PU with an appropriate adapter).
In the case of the heat detectors FC650/TDIFF/57 and FC650/TMAX/78, the class according to
EN 54-5 can be changed
–
see Chapter 3.3.2.7: „Expert mode“ on page 102.
At the time of shipment, the class according to EN 54-5 is marked by means of a label on the bottom
of the detector. If you should change the class, the label has to be updated manually.
With all Series FC650 detectors, the Programming Unit FI700/PU (or the FI750/PU with an appropriate
adapter) can be used to determine the function of the status LED in the normal condition (dark/flashing).
The Series FC650 detectors can be used with the Detector Bases FC600/BR, FC600/BRD and
FC600/BREL.
2.4.2.1 Arrangement of wires in Detector Base FC600/BR, FC600/BRD, FC600/BREL
Strip the insulation just as short as the terminal requires for connection. The alarm resistor R = 1kOhm
between terminals „R+“ and „+“ is already connected. Keep in mind to connect the end-of-line element
(resistor or capacitor) at the terminals „R+“ and „OUT“ of the last element.
The removal of a detector from the Detector Base FC600/BR will open the conventional zone and a
fault (broken wire) will be displayed at the panel.
The use of the Detector Base FC600/BRD, which has a built-in diode, prevents the conventional zone from
being opened when a detector is removed from its base. As a consequence, a capacitor has to be defined as
end-of-line element – for further instructions please consult the corresponding manual of the fire detection
panel.
If a Remote Indicator PA58-3 is used, a 1kOhm series resistor has to be inserted between terminal
„RA“ of the detector base and the Remote Indicator PA58-3. Since detector production code 2011/48,
the series resistor can be omitted.
