NOHMI BOSAI PDCJ001-D Non-Explosion-Proof Type
Made in Japan
Manufacturer: NOHMI BOSAI
Model: PDCJ001-D
Descriptions of PDCJ001-D
- Nohmi’s infrared three-wavelength flame detector quickly detects fire even in places with ventilation flow, external air, or high ceilings where detection is often difficult for the ordinary detectors.
- This high-sensitivity detector is suitable not only for large spaces but also for outdoor facilities.
Features of PDCJ001-D
1. High sensitivity
Catches the flame of 33 cm² normal heptane fire tray at a distance of 60 m. (It is also possible to detect flames more than 60m away depending on the scale of the flame.)
2. Reliable fire detection
The energy intensity of the three wavelength bands in the CO₂ resonance radiation band and the flicker of the flame are judged as “fire” by an advanced algorithm to suppress false alarms.
3. Equipped with self-diagnosis function
The internal circuit is constantly checked, and if an error occurs, a trouble signal is transmitted. The contamination of the light-receiving window is also automatically checked.
