Electric Fire Pump Controllers (600V max.)
Full service Firetrol® Fire Pump Controllers are factory assembled, wired and tested as a unit , completely conforming to the latest edition of NFPA-20, Installation of Stationary Pumps for Fire Protection and NFPA-70 (National Electrical Code). Firetrol controllers are listed by Underwriters Laboratories, Inc., in accordance with UL218, Standard for Fire Pump Controllers, and approved by Factory Mutual (FM)*.
Electric Fire Pump Controllers in general are classified by starting method, as full voltage or reduced voltage starting. The distinguishing factor in these starting methods is the amount of current (amperage) that is drawn by the motor during its initial starting process (inrush). The inrush amperage can be generally expressed as a factor of the motor full load amperage. The normal power source must be able to handle the current inrush that occurs during starting. If the fire pump is to be operated from an emergency power source, such as a generator set, the emergency source must also be able to handle the current inrush.
Some types of reduced voltage starting require a motor specifically wound for that type of starting. It is the pump suppliers responsibility to provide the correct type motor for the starting method you specify.
* Limited Service Controllers are not FM Approved, and FTA3100 Variable Speed Fire Pump Controllers are not FM approved at this time.
