1. Product Description
With their low profile design, flush−mounted installation and possibilities for color ton-
ing, the fire detectors in the 500 series open up a new dimension with respect to aes-
thetic and functional demands.
The cooperation of engineers and designers has created the timeless, innovative de-
sign of this detector, which integrates pleasantly into the ceiling. 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 adjust-
ment 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 of the detectors even in areas
that must be free of protrusions.
Thanks to the geometric arrangement of two separate optical sensor systems, the de-
tectors 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 centime-
ters below the ceiling.
The contamination level is measured constantly. Contamination of the detector sur-
face leads to an active adjustment of the threshold (drift compensation) and a fault indi-
cation at the panel in the case of heavier contamination.
The detector is available as a scattered light fire detector only or as a multisensor de-
tector 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 FAP−500 detectors can be connected directly to the Local SecurityNetwork LSN.
Accessories
The detectors are generally mounted flush with the ceiling in false ceilings. The detec-
tor 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.
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).

In the GB−base versions, integrated jumper elements are provided that preserve the
loop function if the detector is removed.
All bases have an integrated strain relief for false ceiling cables.
The connection terminals are easily accessible. Cables up to 3.3 mm2in cross section
can be used.
An innovative concept for locking the detector module utilizing the push−in/push−out prin-
ciple 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.

1.1. System Description
All detectors in the 500 series are equipped with two optical sensors and a pollution
sensor. The FAP−OC 500 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 inter-
nal 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 corre-
sponds with the characteristic diagram of the installation location that was selected
during configuring.

1.3. Functional Description of the Sensor Technology
Optical sensor (smoke sensor)
The optical sensor (Fig. 1., Pos. 1) operates according to the scattered light principle.
The LEDs (Fig. 1., Pos. 3) transmit light at a defined angle into the measuring area
(Fig. 2., Pos. 7). In case of fire, the light is scattered by the smoke particles and strikes
the photo diodes (Fig. 1., Pos. 2), which transform the quantity of light into a propor-
tional 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 (am-
bient 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 char-
acteristics 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 (Fig. 1., Pos. 4) detects mainly the carbon monoxide (CO) that is pro-
duced 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 distur-
bance 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 continu-
ously by the pollution sensor (Fig. 1., Pos. 6). A three−stage contamination display can
be read out at service (see Chapter 7.1.).

1.4. 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 conta-
minated, 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
The 500 series detectors are approved for indoor use only!
The detectors must be installed exclusively in the FAA−500 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 surface
mount back box.
DCountry−specific standards and guidelines must be observed during the planning
phase.
DThe FAP−OC 500, like the FAP−O 500, is planned according to the guidelines for
optical detectors; see DIN VDE 0833 Part 2 and VdS 2095.
DA hemispherical space (see Fig. 3., Pos. 2)
with a radius of 50 cm must remain free
below the detector (Pos. 1).
Care must be taken to ensure that no peo-
ple, larger animals, plants, opening doors
or any objects intrude into this area and
that no parts of the detector surface be-
come covered.
DThe detector may only be installed in a position which is out of arm’s reach.
Minimum installation height recommended by BOSCH: 2.70 m.
DThe 500 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).
DThe detectors must be mounted so that they are not exposed to any direct sunlight.
DA minimum distance of 50 cm from lamps must be maintained.
The detectors may not be mounted in a cone of light from lamps.
DThe standard spring inside the bases allows detector mounting in false ceiling
panels. For concrete and wooden ceiling, replace with the FAA−500−SPRING with
red marking (ordering information see section 6.2.).
DMaximum permitted air speed: 20 m/s.
DMaximum number of FAP−500 detectors connectable to the Local SecurityNetwork
LSN:
−BOSCH LSN fire panels: up to 28 detectors per NVU as loop or stub line
−Modular Fire Panel FPA−5000: up to 85 detectors per LSN 0300−Modul.

3. Programming
LSN detectors are programmed according to the required operating mode.
Programming is carried out with the programming software using a PC or laptop con-
nected to the fire panel.
The suitable response sensitivity of the multisensor detector is programmed by speci-
fying 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 dis-
turbance 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, consider-
ably increases the fire detection reliability and lowers the false alarm rate.

In the case of the optical FAP−O 500 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.

For execution of the function test for the FAP−O 500 and FAP−
OC 500 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 de-
tector with the help of a magnet.

5. Mounting Notes
The 500 series detectors may only be installed with an FAA−500
series detector base in combination with a FAA−500−BB ceiling
mount back box or an FAA−500−SB surface mount back box.
5.1. Ceiling Mount Back Box
The ceiling mount back box (Fig. 4.) is made of white
polypropylene.
It has four cable bushings with tightly−closing
rubbers lips of polyflam that are suitable for cable
diameters up to 1.4 cm.
When used with a base, approx. 30 cm of cable
length can be accommodated in the upper area of
the ceiling mount back box.
The false ceiling may have a maximum thickness of 32 mm.
Above the false ceiling, a free height of at least 11 cm is required.
DBore a circular hole with a diameter of 130 mm (tolerance −1 mm to +5 mm) in the
false ceiling.
.A hole saw with Ğ133 mm can be obtained from:
KOMET Metal Cutting Saws GmbH & Co. KG, Alte Str. 28, D−79576 Weil am
Rhein, Tel. ++49−7621−9783−0, www.komet.de

DPull the cable through one of the cable bushings. A cable tie around the cable
sheath will secure the cable against being pulled out accidentally.
DInsert the ceiling mount back box in the false ceiling from below.
DA triangular marking (see Fig. 6., Pos. M) is impressed into the outer edge of the
ceiling mount back box. Turn the ceiling mount back boxes so that all markings are
in a line. In this way, the long, middle windows of the detectors will later appear in
a line to give a harmonious overall visual effect.

5.2. Detector Base / Detector Base with Relay
The base housings (Fig. 7.: Side view of
base) are made of white polycarbonate.
The screw terminals (for cables with cross sec-
tion from 0.3 mm2to 3.3 mm2)guarantee a se-
cure electrical connection through the clamped
contacts when mounting the detector.
The bases are provided with three mounts
for cable ties.
.These can be used for fastening the base during the wiring−up.
Detector bases with relay (FAA−500−R und FAA−500−R−GB) can
only be used in combination with the modular fire panel series 5000.
In cases where relay bases are used, no external detector alarm
display can be connected.
Connecting the base
DWire up the LSN base according to the labeling in the outer ring (see Fig. 8.,
Pos. 3).
