1. Product description
The series 120 non−automatic fire detector is used for manual alarm triggering in conventional
line technology (GLT). The line is monitored according to the principle of voltage reduction and
increase.
The Form H detectors are designed for exterior areas, the Form G detectors for interior areas.

2. Features
DManual call point and stop device: Trigger alarm by pushing the button. After alarm
triggering, the push button is adjusted.
DDetector query routines with evaluation and multiple transmission.
DDisplay (LED) for triggered alarms or inspection evaluation.
DSecond contact with connections for panel control.
DSame design for interior use (Form G) and exterior use (Form H).
DAvailable in different colour variants; see order overview.
DFor the red colour variants, a burning house" is applied to the detector housing in the
factory.
DVariable labelling is possible with foil sets for the blue and yellow colour variants.
DFor exterior use in extreme environmental conditions, the detector is equipped with an
especially resistant PC board (parylene layering) and with a seal in the detector door.

3. Planning notes
DNon−automatic fire detectors must be mounted visibly along escape and rescue routes
(e.g. exits, passageways, stairwells) and be easily accessible.
DAn installation height of 1400 mm ($200 mm), measured from the middle of the push
button to the floor, must be maintained.
DNon−automatic fire detectors must be sufficiently lit with sunlight or another light source
(including emergency lighting if present).
DThe distance between non−automatic fire detectors should not exceed 100 m according
to DIN 14 675 or 80 m according to VdS.
DIn high risk areas, non−automatic fire detectors should be installed at intervals of max. 40 m
(VDE 0833 Part 2, Point 7.2.6).
3.1. Maximum number of detectors that may be connected
In accordance with VdS guidelines, a maximum of 10 non−automatic fire detectors may be
connected to a primary line.
The test detector can be used for primary lines with automatic fire detectors. It is con-
nected to the electrical end of the primary line (max. 1 test detector per primary line).
3.2. Norms, guidelines and planning recommendations
Additional norms, guidelines, and planning recommendations with respect to installation loca-
tion etc. must be taken into account (see fire detector manual).
The regulations of the local fire services must be observed.

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:
DDetectors 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).
DThe line voltage (Umax) must not exceed 33 V!
DThe maximum current (Imax) must be limited to 130 mA!
Fire detector cable:
DOnly fire detector cables that conform to DIN VDE 0814 may be used.
DThe total cable capacity (Cmax) must not exceed 1 F!
DThe total cable inductivity (Lmax) 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.

6. Functional description
6.1. Manual call point
Manual call point and stop device: In the event of an alarm, the glass pane (2) is broken
first, then the manual call point (3) is pressed hard.
This activates the microswitch for alarm triggering and the display LED (4) flashes.
A locking mechanism holds the pressed push button down.
The pressed push button is reset by manually activating the reset lever (5) or by opening
the detector door (1) ⇒The alarm is reset and the display LED goes out (4).

dThe non−automatic fire detector is designed for wall mounting.
dThe installation height, according to VdS regulations, is 1400 mm
(±200 mm) from the floor to the centre of the push button.
dThe connection cables can be surface or flush−mounted.
The cable ducting should be carried out using the intended openings in
the housing (see 7.2 Cable duct).
dThe installation location is to be selected so that approximately 35 mm
space remains free on the right−hand side for opening the door.
