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).
