Description of FDPJ Series
- The FDPJ series rate-of-rise heat detectors operate on the pneumatic principle, i.e., the expansion of heated air in the air chamber, and respond to rapid rise in temperature caused by a fire.
- A slow or gradual temperature rise as would result from a heating system in the building does not activate the detector because any moderate excess air is released into the atmosphere through the air vent.
- By the use of a common base, the FDPJ series rate-of-rise heat detectors are interchangeable with NOHMI smoke detectors (FDK series).
- This interchangeability enables optimum 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 lamp by which it is possible to readily identify the alarming detector. This feature facilitates the functional check of the detector.
