Fire Safety
The combination of optical and thermal sensor signals optimizes detection
reliability. This has the following advantages:
Early detection of all types of fire, whether they generate light or dark smoke, or
l
no smoke at all.
The neural fire detector can be operated at a lower sensitivity level and thus
l
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.
In addition, the heat sensors make it possible to detect fires without smoke
generation.
The radio fire detector can be used purely as an optical smoke detector or purely
as a heat detector. This is determined by selecting one of the following sensor
modes (using the control panel):
Sensor mode 0: Application as neural fire detector
l
Sensor mode 1: Application as heat detector
l
Sensor mode 2: Application as smoke detector
