  • Page 6: Structure And Function

    Structure and function Overview 2 Structure and function 2.1 Overview The linear smoke detector FDL241‑9 detects fires according to the principle of light attenuation by smoke. The linear smoke detector works together with a reflector, which is installed opposite the detector. Properties ●...
  • Page 7: Infrared Ray

    Structure and function Overview When smoke is present, part of the infrared ray is absorbed when it encounters the smoke particles, while another part is scattered by smoke particles. The rest reaches the reflector and is returned to the receiver. The infrared ray is attenuated further.
  • Page 8 Structure and function Overview ● Effective range (1): The effective range is the connection between the transmitter, reflector and receiver. ● Core range (2): In the core, enough radiation energy is present to operate the system. ● Scattering range (3): The radiation energy in the scattering range is insufficient and does not ensure the functionality of the system.
  • Page 9 Structure and function Overview One turn of the knurled screw moves the infrared ray by approx. 0.8 m per 100 m distance. 10° 10° 100 m Figure 5: Horizontal adjustment range 1 Diameter of the core 5° 5° 100 m Figure 6: Vertical adjustment range 1 Diameter of the core A6V10332811_e_en_-- 9 | 44...
  • Page 10: Reflectors

    Structure and function Reflectors 2.3 Reflectors Retro-reflectors reflect rays of light that reach them in parallel. The reflector does not necessarily have to be installed at a right angle to the ray of light. Vibrations and distortions on the mounting surface do not interfere with this. Interfering light is also reflected in parallel and does not therefore reach the receiver.
