The FDO181 wide-spectrum smoke detector is an optical smoke detector with an optical sensor. It works according to the principle of forward scattering. The detector reacts extremely sensitively on light aerosols caused by fire. The increased sensitivity makes possible the early detection of smoldering and open fires.

• Intelligent detector with built-in CPU, providing advanced distributed intelligence for
  optimum reliable detection principle
• Two kinds of sensitivity setting (standard, sensitive)
• Opto-electronic sampling chamber more reliable and accurately detects fire
• Automatically address setting without encoder setting or DIP switch
• Resistant to environment and interference factors such as dust, fibres, insects,
  humidity, extreme temperatures, electro-magnetic interference, corrosion, vapors,
  vibration, synthetic aerosols and atypical fire phenomena
• All-around visible alarm indicator
• Communication via FD18-BUS, polarity free connection
• “Sticker Method” easy for commissioning
