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.
