Radio Frequency Fire Detection System Short Information | en 5
Bosch Sicherheitssysteme GmbH Operation Guide 2016.04 | 6.0 | 4.998.120.885
2 Short Information
The RF fire detection system consists of 1 FK 100 RF Interface Module and up to 30 RF smoke
detectors (DOW 1171 RF Smoke Detector and/or SMF121 RF Manual Call Point). As an LSN
element, FK 100 RF Interface Module is switched in a loop or stub line and forms the interface
between the RF smoke detectors and the fire panel.
Transfer of information between detector and interface module is bi-directional. If a base
channel is occupied by an external system, the system immediately switches to a secondary
channel to guarantee alarm transmission.
The RF fire detection system works in a frequency range of 868 to 870 MHz. Within this range,
a few channels are exclusively defined for radio applications in security systems. This
guarantees an extremely high level of operational stability.

The LSN part in the interface module is powered via the LSN (LSN = Local Security Network).
The radio module is powered via an auxiliary power supply. An integrated microcontroller
drives interfaces and user elements and is responsible for data transfer between the RF fire
detector and the fire panel. The interface module has a tamper contact, a reed contact for
manual activation of the configuration mode and three LEDs for the operating status display.

4 Installation/Configuration Notes
When planning the RF fire detection system it must be ensured that the individual RF
detectors have an optimum radio connection to the RF interface module. In a building, the
range for the RF fire detection system generally depends on the reflection and absorption
behavior of the materials used and the applicable ceiling and wall construction. There is no
need for a visual line between the individual radio components.
Depending on whether the configuration or the materials of the wall and ceiling constructions
are known, there are various options to plan the RF fire detection system:
– Planning with manual calculation of the attenuation (see chapter Planning the RF Fire
Detection System, page 11)
– Planning with DZW 1171 Radio Test Unit (see chapter Planning a RF Fire Detection System
with DZW 1171 Radio Test Unit, page 13)
– Planning using PC or laptop with Radio Spy 1 Field Strength Measuring Unit and Software
4.1 General Limits
– Recommendation: Maximum of 10 x FK 100 LSN Interface Modules per LSN ring.
– Maximum of 30 RF fire detectors or 10 RF manual call points per interface module.
Interface modules, RF fire detectors and RF manual call points count in each case as one
LSN element (e.g. 1 interface module + 15 RF fire detectors = 16 LSN elements).
– A maximum of 127 LSN elements are permitted for each LSN ring.
– Attenuation of a transmission path < 90dB
4.2 Planning the RF Fire Detection System
To be able to create an optimum radio connection, the attenuation of a transmission must be
< 90dB. The attenuation values of the construction elements located on the transmission path
in question (walls, ceilings etc.) must also be added to determine the actual attenuation at the
mounting location in the case of attenuation owing to the distance.
The attenuation for the individual transmission paths, depending on distance and including
the construction elements installed, can be calculated from the following tables.
Where the distance is doubled, the attenuation increases by approx. 17dB.

Figure4.7: Calculation example for planning of RF fire detection system
The individual transmission paths (FS) can be calculated as follows:
– FS 1: Attenuation corresponding to distance + attenuation through reinforced concrete
ceiling
=> 40dB + 30dB = 70dB
– FS 2: Attenuation corresponding to distance
=> 35dB
– FS 3: Attenuation corresponding to distance + attenuation through concrete wall
=> 53dB + 6dB = 59dB
– FS 4: Attenuation corresponding to distance + attenuation through concrete wall
=> 57dB + 6dB = 63dB
– FS 5: Attenuation corresponding to distance + attenuation through reinforced concrete
ceiling + concrete wall
=> 67dB + 30dB + 6dB = 103dB
The transmission paths 1 to 4 can be operated. In the case of transmission path 5, the
detectors are no longer reached, as the attenuation exceeds 90 dB.

1. Switch modules A and B on.
The LEDs (4) next to the switches light up if there is sufficient battery voltage. The
specified radio connection between the modules is initiated automatically and the LED on
module A flashes while the radio connection is being established. As soon as the radio
connection is set up, LED (5) on module A goes out and LED (5) on module B stays
continuously lit.
2. Position module A as close as possible to the RF interface module.
3. Connect module B to the service pole and move to the designated RF detector
installation location.
As long as the LED (5) on module B stays continuously lit, the transfer of the radio signal
is guaranteed (attenuation < 90 dB). If the LED (5) on module B starts to flash, the
maximum radio range has been reached (attenuation 85 to 89dB); however, the radio
signal is still strong enough for fault-free operation. If the LED (5) on module B goes out,
the RF interface module or RF detector installation location is outside the radio range.

The RF interface module is surface-mounted. The cables can be surface-mounted or flush-
mounted. For this reason, pre-punched openings are provided on the lower part of the
housing (on the sides and the base). The pre-punched openings can be punched out more
easily, if the PC board is first removed.
1. Remove the housing cover from the lower part of the housing.
2. Push off the two snap-fit hooks (2) on the left or right of the PC board carefully and
remove the PC board (1).
3. Punch out the required openings for the surface-mounted (3) or flush-mounted (4) cable
feed and screw the lower part of the housing to a dry, even surface.
4. Insert the PC board (1) again and wire up the connections (for terminal assignment see
chapter Connection of FK 100 LSN RF Interface Module to the Fire Panel, page 18.
5. Use hose clips to secure the connection cable to the bars (5) to relieve strain.
5.2 Installing DOW 1171 RF Smoke Detector
Notice!
Do not connect the batteries in the RF smoke detector base until the RF interface module is
permanently connected to the power supply. If this is not the case, the detector constantly
tries to establish a connection to the RF interface module, which substantially reduces the
service life of the batteries.

2016.04 | 6.0 | 4.998.120.885 Operation Guide Bosch Sicherheitssysteme GmbH
7 Commissioning a RF Fire Detection System
Notice!
If at all possible, do not switch off the power supply to the RF interface module after
commissioning the RF fire detection system, as during a power failure all RF detectors in the
relevant RF fire detection system search for their RF interface module and are therefore
permanently in send mode. This considerably reduces the life of the batteries.
If the power supply to the RF interface module has to be interrupted for a lengthy period (> 1
hour), please disconnect the batteries in the RF detectors.
Only those RF interface modules, RF smoke detectors and RF manual call points can be
commissioned, which are either new or in the delivery state.
– FK 100 LSN RF Interface Module:
– When commissioning with WinPara / FSP-5000-RPS, a RF interface module that has
already been configured will be automatically reset into the delivery state.
– When commissioning without WinPara / FSP-5000-RPS, a RF interface module that
has already been configured must be manually reset into the delivery state (see
chapter Resetting the RF Interface Module to the Delivery State, page 26.
– DOW 1171 and SMF121 RF Detectors:
When commissioning, RF detectors that have already been configured must always be
manually reset into the delivery state. This is described in the respective chapter for
logging in.
For the complete commissioning of the RF fire detection system, the RF interface module
must be set up first (see chapter Commissioning the FK 100 LSN RF Interface Module via
WinPara / FSP-5000-RPS, page 21) and then the individual RF detectors must be logged into
the RF interface module (see chapter Commissioning DOW 1171 and SMF121 RF Detectors,
page 21).
Autodetection
Autodetection refers to the automatic identification of all connected peripherals according
their topologies by the panel.
Notice!
With loop wiring, make sure that you have logged in at least 1 RF detector to the RF interface
module. This allows the panel to identify and display the loop correctly.
Assignment of the base channels
16 base channels are available for the connection from the interface module to the fire panel.
When commissioning, each RF fire detection system automatically searches out a B-channel in
a specific sequence. Once all 16 base channels have been called up in sequence, the
assignment starts again at the first base channel, leading to a double assignment.
Notice!
Ensure without fail that the individual RF fire detection systems are installed so that there are
no errors in the allocation/logging in of the individual RF detectors to the RF interface module
due to double assignment.
For optimum planning, use the Radio Spy 1 Field Strength Measuring Unit including Software.
The base channels can be displayed in WinPara:
