Nohmi Bosai FDP219A-X Heat detector


The FDP219A-X rate-of-rise detectors operate on the pneumatic principle. The expansion of heated air in the chamber will respond to rapid rise in temperature caused by fire. The use of heating systems in buildings will result in a slow or gradual temperature rise, and will not activate the detector. The FDP rate-of-rise detectors are interchangeable with NOHMI smoke detectors. This enables other detector types to be chosen for  protected areas in case of change in the use of the rooms. The detector is equipped with a response indicator by which it is possible to readily identify the alarming detector. This feature facilitates the functional check of the detector.
