3.3. Use in explosive areas
All non−automatic detectors from fire detector series 120 conform to device ca-
tegory 3G, gas group IIB and temperature class T6, in accordance with the Euro-
pean guideline 94/9/EG (ATEX). Thus the detectors may be used in Zone
2 areas where there is danger of explosion!
Limiting values:
D Detectors may only be operated with central units whose line output is energy−limited
according to EN 50021.
. This applies to all Bosch fire panels (BMZ).
D The line voltage (U
max
) must not exceed 33 V!
D The maximum current (I
max
) must be limited to 130 mA!
Fire detector cable:
D Only fire detector cables that conform to DIN VDE 0814 may be used.
D The total cable capacity (C
max
) must not exceed 1 F!
D The total cable inductivity (L
max
) must not exceed 0.01 H!
. The cable type J−Y(ST)Y08, in accordance with DIN VDE 0815 (table 10), has a capacity of
120 F at a length of 1000 m.
3.4. Labelling variants
The detectors can be individually adapted to the location/application with optional label-
ling variants. This excludes detector variants FMC−120−DKM−G−R and
FMC−120−DKM−H−R, to which the burning house" symbol has already been applied.
The self−adhesive labelling foils are stuck on the front panel of the detector.
