In addition, the heat sensors make it possible to detect fires without smoke
generation.
The combination of optical and thermal sensor signals optimizes detection
reliability. This has the following advantages:
z Early detection of all types of fire, whether they generate light or dark smoke, or
no smoke at all.
z The neural fire detector can be operated at a lower sensitivity level and thus
achieves a higher immunity against false alarms which may otherwise be
caused by cold aerosols (e.g. by smoking, electrical welding, etc.). In the case
of an open fire, the smoke sensitivity is heightened by the temperature
increase, which means that a detection reliability level that is comparable to
that of the wide-spectrum smoke detector can be achieved.
The neural fire detectors FDOOT241-8/9 may as well be applied either as optical
smoke detectors or as out-and-out heat detectors. This is possible by selecting one
of the following sensor modes (with the detector exchanger and tester or on the
control panel):
z Sensor mode 0: Application as neural fire detector
z Sensor mode 1: Application as heat detector
z Sensor mode 2: Application as smoke detector
In sensor mode 1 or 2 the parameter sets of the heat detector FDT241 or of the
wide-spectrum smoke detector FDO241, respectively, can be selected. Then,
these neural fire detectors behave like the heat detector FDT241 or smoke detector
FDO241.
3.3.1.1 Variants of the FDOOT241-9
The neural fire detector FDOOT241-9 is available in three different variants A, B
and C. The compatibility differs depending on the variant. The following table
provides an overview of the compatibility of the different variants. Refer to
document 008331 'List of compatibility' for compatibility details.

Notes
z Variant B has been available only as kit (FDOOT241-9M) consisting of the
neural fire detector and the detector base FDB201.
z The specifications of variant B largely correspond to those of variant A. Any
possible deviations are marked accordingly in this document.
z Variant C is available both as single detector and as kit (FDOOT241-9M).
