1 Product Description
Figure 1.1 520 Series Fire Detector
The 520 Series Fire Detectors combine the advantages of the LSN improved technology with
the aesthetic benefits of flush-mounted installation and the option to choose the color. The
detectors are specially designed for connection to the modular fire panel Series 5000 with the
significantly extended LSN system parameters. They can also be connected to all classic LSN
fire panels.
The detectors with associated trim ring are available in the versions white and transparent
with color toning inserts. Through the use of the supplied color toning inserts, optimum
adjustment to many different environments becomes possible.
The lack of an optical labyrinth and their easily-cleaned smooth surface means the detectors
are also suitable for applications in high-dust areas.
The low profile, flush-mounted design allows the use the detectors even in areas that must be
free of protrusions.
Thanks to the geometric arrangement of two separate optical sensor systems, the detectors
are not sensitive to interference, such as that caused by insects. The scattered light volume
that is evaluated by the sensors is located in the free space a few centimeters below the
ceiling.
The contamination level is measured constantly. Contamination of the detector surface leads
to an active adjustment of the threshold (drift compensation) and a fault indication at the
panel in the case of heavier contamination.
The detector is available as a scattered light fire detector only or as a multisensor detector
with an additional gas sensor.
The combination of scattered light detector and gas sensor allows the evaluation of signals
with the help of modern signal processing methods. The result is high immunity against
deceptive alarms and extended application possibilities in environments that are not suitable
for pure scattered light smoke detectors.
The integrated rotary switches allow for an automatic or manual allocation of addresses.
The FAP-520 Detectors can be connected directly to the Local SecurityNetwork LSN.
Accessories
The 520 Series Detectors are generally mounted flush with the ceiling in false ceilings. The
detector and base are installed in a robust ceiling mount back box. In addition, a housing for
mounting within concrete ceilings can be used.
For special applications where recessed ceiling mounting is not possible, a surface mount
back box is available. This is used as an alternative to the ceiling mount back box.
The surface mount back box with damp room seal also allows the detector to be used in a
humid environment.

F.01U.025.877 | 2.1 | 2011.11 Operation Guide Bosch Sicherheitssysteme GmbH
For special applications, e.g. control of an emergency door in accordance with DIBt, base
variants are available with relay (only in combination with the Modular Fire Panel FPA-5000).
All bases have an integrated strain relief for false ceiling cables.The connection terminals are
easily accessible. Cables up to 3.3 mm2 in cross section can be used.
An innovative concept for locking the detector module utilizing the push-in/push-out principle
allows very quick and easy insertion and exchange of the click and lock detector.
For the detector test and detector exchange, a special user-friendly service accessory is
available.

1.2 System Description
All detectors in the 520 Series are equipped with two optical sensors and a pollution sensor.
The FAP-OC 520 Multisensor Detector contains a gas sensor as an additional detection
channel.
The response sensitivity of the detector can be programmed with the programming software
via the LSN network. All sensor signals are analyzed continually by the internal signal
evaluation processor and are linked with each other.
By linking the optical sensors and the gas sensor, the OC detector can also be used in places
where the work carried out gives rise to small amounts of smoke, steam or dust. The alarm
will only be triggered automatically if the signal combination corresponds with the
characteristic diagram of the installation location that was selected during configuring.

1.4 Functional Description of the Sensor Technology
Optical sensor (smoke sensor)
The optical sensor (see Figure 1.3 (1)) operates according to the scattered light principle.
The LEDs (see Figure 1.3 (3)) transmit light at a defined angle into the measuring area (see
Figure 1.4 (7)). In case of fire, the light is scattered by the smoke particles and strikes the
photo diodes (see Figure 1.3 (2)), which transform the quantity of light into a proportional
electrical signal.
The effects of daylight and commercial lighting sources are filtered out with an optical
daylight filter and by the use of electronic filtering and phase-locked rectification (ambient
light stability: glare test DIN EN 54-7).
The various light-emitting and photo diodes of the detector are individually activated.
Consequently, signal combinations are produced that are independent of each other and
ideally suitable for the detection of smoke, which makes it possible to differentiate between
smoke and interference agents (insects, objects). In addition, the time characteristics and the
correlation of the optical sensor signals for the fire or interference detection are evaluated.
Moreover, plausibility checking of the various signals makes it possible to detect errors in the
evaluation electronics and the LEDs.
Chemical sensor (CO gas sensor)
The gas sensor (see Figure 1.3 (4), only FAP-OC 520(-P)) detects mainly the carbon monoxide
(CO) that is produced by a fire, but it also detects hydrogen (H) and nitrogen monoxide (NO).
The basic measuring principle is CO oxidation on an electrode and the measurable current
that arises from this. The sensor signal value is proportional to the concentration of gas.The
gas sensor supplies additional information in order to reliably suppress the disturbance
variables.
The CO sensor is monitored by supervision of the internal capacity. If the capacity lies outside
the permitted range, a malfunction signal is output on the fire panel. In this case, the detector
continues to operate purely as a scattered light smoke detector.
Pollution sensor
The contamination level of the detector surface is measured and evaluated continuously by
the pollution sensor (see Figure 1.3 (6)). A three-stage contamination display can be read out
at service (see Section 5 Maintenance and Service, page 26).
1.5 LED Operation
The two-color LED of the detector indicates the operation and alarm statuses.
During the whole life cycle, the sensors are self-monitored and the sensitivity is self-adjusted
according to the programmed threshold. In case the detector is heavily contaminated, a
message is sent to the fire panel.
In case of an alarm, the LED flashes red. The detector is set back to standby if the alarm is
reset via the fire panel and if the cause of the alarm is gone.

2 Planning Notes
2.1 General Notes
– Country-specific standards and guidelines must be observed during the planning phase.
– The FAP-OC 520, like the FAP-O 520, is planned according to the guidelines for optical
detectors (see also EN 54 and VDS 2095).
– A hemispherical space (see Figure 2.1 (1)) with a radius of 50 cm must remain free below
the detector (see Figure 2.1 (2)).
Care must be taken to ensure that no people, larger animals, plants, opening doors or
any objects intrude into this area and that no parts of the detector surface become
covered.
Figure 2.1 Radius
– The detector may only be installed in a position which is out of arm's reach.
Minimum installation height recommended by BOSCH: 2.70 m.
– The 520 Series Detectors may not be installed in rooms with data transmission by means
of high-intensity infra-red light (e.g. in rooms with IR systems for interpreters).
– The detectors must be mounted so that they are not exposed to any direct sunlight.
– A minimum distance of 50 cm from lamps must be maintained.
The detectors may not be mounted in a cone of light from lamps.
– By default, the bases are equipped with a spring for mounting the detector in concrete
and wooden ceilings. This spring is identifiable by the red marking. For mounting a
detector in a false ceiling panel you can use the additional, softer spring in the package.
In this use case, the detector must not be subjected to strong vibrations (> 350 m/s).
– Maximum permitted air speed: 20 m/s.
2.2 Network Topologies for LSN Improved
In an improved version Local Security Network (LSN improved), the detectors can be
configured as a loop, a stub or T-tap or in any mixed loop or T-tap structures. However, it is
important to note that mesh structures cannot be created.
The LSN improved version allows T-taps on stubs or loops and any number of nodes, branches
per node and elements per branch as long as the maximum number of elements does not
exceed 254.
Connections can be positioned anywhere along the LSN line.
NOTICE!
The 520 Series Detectors are approved for indoor use only! The detectors must be installed
exclusively in the FAA-500 Series Bases provided. In addition, the detector base must be
installed in an FAA-500-BB Ceiling Mount Back Box or in an FAA-500-SB-H Surface Mount Back
Box.

3.3 Address Allocation
The detector's address is allocated by setting three rotary switches located on the back of the
device.
Use a flat-bladed screwdriver to position each switch. The switches will click when turned.
All detectors delivered ex factory are set to 0 0 0.
Figure 3.8 Rotary switches
When connecting the detectors to the LSN fire panels BZ 500 LSN, UEZ 2000 LSN or
UGM 2020, all detectors have to be addressed by CL 0 0.
When connecting the detectors to the Modular Fire Panel FPA1200/FPA-5000, the address
allocation is done automatically or manually.
In case of a manual allocation, all detectors of the same loop, stub or T-tap have to have an
address between 001 and 254. Addresses between 255 and 299 are not allowed and produce
a fault message on the fire panel.
If the addresses shall be allocated automatically by the fire panel, all detectors must have the
address 0 0 0.

3.7 External Detector Alarm Displays
If the detector is not directly visible or was mounted in rooms that are inaccessible, an
external detector alarm display is used in the corridors or in the access routes to the
corresponding section of the building or rooms.
The red alarm indication corresponds to DIN 14 623.
3.7.1 Mounting Notes for the Remote Indicator FAA-420-RI
FAA--500/FCA-500 FAA--500--SB-H
NOTICE!
In cases where relay bases are used, no external detector alarm display can be connected.
NOTICE!
If unshielded cables are used, the cable length between an LSN detector and an external
detector alarm display is restricted to a maximum of 3 m.
If shielded cables are used, make sure that the total cable length (= sum of all cables leading
to external detector alarm displays within one loop or stub) does not exceed 500 m.
NOTICE!
The FAA-420-RI must be installed such that the broad side of the red alarm indication (see
Figure 3.14 (2)) follows the observer’s line of sight.
WARNING!
If the maximum current consumption of the connected detector is larger than 20 mA, it can
result in malfunctions and damage to the External Detector Alarm Display.
In order to prevent damage to the device, ensure that the maximum current consumption of
20 mA is not exceeded.
Bosch automatic detectors already have an internal resistance which limits the current
consumption.

F.01U.025.877 | 2.1 | 2011.11 Operation Guide Bosch Sicherheitssysteme GmbH
4 Programming
LSN detectors are programmed according to the required operating mode.
Programming is carried out with the programming software using a PC or laptop connected to
the fire panel.
The suitable response sensitivity of the multisensor detector is programmed by specifying the
operating location (e.g. computer room, office, large kitchen). The selection of the operation
location determines the optimal characteristic diagram for the fire and disturbance variable
evaluation.
If, according to the operating location, a low sensitivity is set for the optical sensor, the alarm
goes off only if the detector senses high levels of smoke and of CO at the same time. This is
the case with open or smouldering fire.
Programming the multisensor detector and linking all detectors by algorithms, considerably
increases the fire detection reliability and lowers the false alarm rate.
In the case of the optical FAP-O 520 detector, the sensitivity of the optical sensors can be set
on three levels. Depending on the operating location, the optical sensor of the detector is
thus adjusted to the environmental conditions. For fire detection, also the time behavior of
the fire characteristics is evaluated. This is very different from the time behavior of the
disturbance variables.

NOTICE!
For execution of the function test for the FAP-O 520 and FAP-OC 520 detector, the detector
must be switched to test mode. This can be carried out via the fire panel or via the reed
switch at the detector with the help of a magnet (see Section 5 Maintenance and Service,
page 26).

F.01U.025.877 | 2.1 | 2011.11 Operation Guide Bosch Sicherheitssysteme GmbH
5 Maintenance and Service
For maintenance and inspection work on security systems, the regulations laid down in
DIN VDE 0833 strictly apply in Germany; these refer to the maintenance intervals specified by
the manufacturer.
– Maintenance and inspection work should be carried out regularly and by trained
technical personnel.
– Bosch Sicherheitssysteme GmbH recommends a functional and visual inspection at least
once a year.
FAP-OC 520
Due to the life expectancy of the gas sensor, the FAP-OC 520 detector switches off the
C sensors after approx. 5 years of operation. The detector will continue to function as an
Odetector.
At the fire panel, an according fault indication is displayed.
The detector should then be exchanged immediately in order to be able to keep using the
higher reliability of detection of the OC detector.
The detector can be wiped over with a soft cloth and a proprietary plastic cleaning agent.
Cleaning should only take place in test mode.
NOTICE!
The 520 Series Detectors do not require to be removed from their bases for routine
maintenance.
If occasionally a detector requires replacement due to a design change or damage to the
device then this should be carried out by a qualified engineer.
This should only be undertaken when the system is offline and the user has made alternative
arrangements for emergency evacuation.

5.2 General Notes for Detector Testing
The FAP-OC 520 detector has an additional sensor for CO detection in case of fire. The CO
sensor provides improved response behavior and increased stability against nuisance alarms
in critical environmental conditions.
For fire detection, FAP-520 detectors use the time behavior of the fire characteristics, which
differs from the time behavior of disruption variables. Therefore, for a functional test, the

detector must be switched to test mode. Switching to test mode can occur in two ways,
which are described in the alternative test procedures (see below).
5.3 Inspection Procedure for FAP-OC 520
5.3.1 1. Alternative
1. On the central unit, switch the detector zone to be inspected into test mode. This
automatically sets the detector into revision operation and readies it for the detector
test.
Only in revision operation the detector’s individual sensors will trigger with the
corresponding test device. For an alarm, all sensors must trigger at the same time. The
C sensor is triggered using CO test aerosol, the O sensors by being covered up. No
O testing gas is required.
2. Now hold the test device under the detector so that the test beaker is flush with the trim
ring and seals it tightly.
Make sure that the test beaker does not tilt, which could cause the detector to be lifted
up and consequently become detached from its fastening.
3. Spray the CO testing gas for approximately 1 sec.
The test head must remain over the detector until the detector has been triggered.
Distribution of the CO testing gas in the test head and therefore the sensor trigger time
can take up to 20 sec.
4. Both scattered light areas are covered by the test beaker, so that both optical sensors
are also triggered at the same time.
5. The detector triggers the alarm and the red alarm LED flashes.
5.3.2 2. Alternative
The detector can be tested in normal operation if a test device with magnet is used.
Figure 5.1 shows the position of the reed switch (Pos. R) in the case of OC detectors.
If you imagine the CO sensor (Pos. CO) to be in a 12 o’clock position, the reed switch (Pos. R)
is located at approximately 2 o’clock.
NOTICE!
Detectors that are programmed for two-detector dependency must be tested in accordance
with the first alternative (in test mode).
NOTICE!
For the detector test, you need:
– Detector test device for optical fire detector (product ID: 4.998.112.071)
– FAA-500-TTL test adapter with magnet (product ID: F.01U.508.725)
For OC detector, in addition:
– CO testing gas for detector with CO sensor (product ID: 4.998.142.221)
NOTICE!
Make sure that the alarm cannot be passed on to higher-level systems. Programmed
activations of the central unit are retained and are executed.

Figure 5.1 Position of reed switch
1. Bring the magnet close to the reed switch.
2. The LED of the detector flashes green once a second as soon as the reed switch has been
triggered. The detector will now remain in test mode for 60 sec with automatically set
test parameters (e.g. reduction of the delay time to 15 sec). The green LED flashes for as
long as the detector remains in test mode.
3. Now hold the test device under the detector so that the test beaker is flush with the trim
ring and seal it tightly.
Make sure that the test beaker does not tilt, which could cause the detector to be lifted
up and consequently become detached from its fastening.
4. Proceed as in the case of the first alternative:
– spray with CO gas
– leave the test device on the detector for approx. 20 sec, until the alarm is triggered
5. Both scattered light areas are covered by the test beaker, so that both optical sensors
are triggered as the same time as the CO sensor (no O testing gas is required).
6. The detector triggers the alarm and the red alarm LED flashes.
5.4 Inspection Procedure for FAP-O 520
5.4.1 1. Alternative
1. On the fire panel, switch the detector zone to be inspected to test mode. This
automatically sets the detector into revision operation and readies it for the detector
test.
2. Hold a sufficiently large object (e.g. the detector test device or the detector exchanger)
in both scattered light areas until an alarm is triggered. No O testing gas is required.
5.4.2 2. Alternative
The detector can be tested in normal operation if a test device with magnet is used.
