A: The National Fire Protection Research Foundation coordinated fire testing using ESFR sprinklers and HVLS fans. The researchers concluded that the fans did not affect the performance of the sprinklers to a level that would be considered unacceptable.

 

Key points to be aware of are:

 

-The Revolution HVLS Fan meets the requirements of NFPA 13 (National Fire Code for Sprinklers) in regards to blocking obstructions below sprinkler heads.

 

-The Revolution HVLS Fan meets the air velocity requirements of FM Global's 2-2 data sheet for ESFR sprinklers.

 

-In some cases, a local fire prevention authority may require that the industrial fans be tied into a building's fire suppression system so that the fans shut off as soon as a fire is detected. The Revolution Fan's control box includes a variable frequency drive that facilitates this. The low voltage wire and relay needed to accomplish this are readily available locally. The instructions for installation are outlined on page 13 in the Revolution HVLS Fan Owner's Manual.

 

-When the Revolution Fan is shut off upon fire detection as described above, the Revolution Fans come to a complete stop in less than 30 seconds, which is another common requirement.
