Fire Detection Systems - Ardea ESD 515

Thanks to the linear design with transmitter and receiver, the ARDEA is used wherever structural situations prevent the installation of conventional point detectors or where the latter can no longer guarantee optimal protection. The ARDEA linear detector is a high-performance detector that detects smoke and fire fast and reliable through absorption measuring and evaluation of the spectroscopical measured variables (frequency analysis). The monitored area can be up to 1600 m2, the monitored length 5 – 150 m. The ARDEA stands out for its simple installation, setting as well as the little maintenance needed. The linear detector is especially suitable for large and high rooms as e.g.:

• Industrial plants
• Churches
• Warehouses, archives
• Cinemas, theatres, conference halls etc.

The ARDEA system consists of two units: the transmitter of infrared light and the receiver. The transmitter sends a beam of a focused IR light to the receiver up to 150 m away where the signal is evaluated. In case of fire, smoke or heat development change the infrared beam. The optimal evaluation (receiver) of the 3 criterias light absorption, frequency development and time related changes allows a reliable identification of smoke or open fire. The presence of dust or mist does not disturb the system. A slow increase of contamination is corrected to a certain degree. When the limit is exceeded (e.g. slowly smouldering fire) an alarm is triggered.
