Smoke detectors

Analog photoelectric smoke detector 4401

Analog photoelectric smoke detector 4401  

  • State of the art detector for highest safety
  • Nuisance alarms reduced by up to 46% by using Advanced Mode:
    • Variable sensitivity and time delay based on smoke changes just before and after fire alarm level has
      been reached
    • A learning function will ensure that the most suitable fire alarm algorithm is always used
  • High-tech mesh net prevents dust and insects to enter the detection chamber
  • Automatic service signal to minimise maintenance costs
