NOHMI BOSAI NN100 Package EX
Made in Japan
Manufacturer: NOHMI BOSAI
Model: NN100
Features of NN100
- Suppresses fires at an early stage effectively.
- Uses highly pressurized gas cylinders.
- The gas discharge emits high noise levels, which may impact sensitive equipment like hard disk drives (HDDs).
- Offers lower noise discharge nozzles for HDD protection.
- Provides recommendations for protecting HDDs, such as sound insulation, stopping HDD operations, and improving data backup measures.
- Adheres to NFPA 75 guidelines by cutting off power to all electronic devices when the fire suppression system activates.
- Prevents room damage from excessive pressure caused by the gas agent discharge using a pressure relief device.
- Includes an exhaust fan to remove products of combustion after fire extinguishing.
- Specifications are subject to change; users should verify the latest details with Nohmi.
Description of NN100
- This system quickly suppresses fires before they spread.
- You should handle the highly pressurized gas cylinders with care, following the indicated cautions.
- The discharge of gas creates high noise levels, which may interfere with modern precision instruments such as hard disk drives (HDD).
- If your environment contains HDDs, using lower noise discharge nozzles can reduce the impact.
- However, even with these nozzles and additional countermeasures like soundproofing or data backup, performance isn’t guaranteed for HDDs.
- NFPA 75 advises cutting off power to all electronic devices simultaneously when the gas suppression system activates.
- In areas protected by this system, the room’s excessive pressure must be released through a relief valve to avoid damage.
- Products of combustion can be harmful, and an exhaust fan should be installed to clear the air post-extinguishment.
- Contact Nohmi for more details or to verify specific information related to installation, operation, or maintenance.
