Description
Firetrol Variable Speed Electric Fire Pump Controllers provide a variable frequency drive (VFD) to control the speed of a centrifugal pump to limit system pressure in a fire sprinkler system. The Firetrol FTA3100S Series stands at the forefront of fire pump control technology. In many fire protection scenarios, a constant-speed pump can create excessive pressure during low-flow conditions, leading to mechanical stress on the entire network. The FTA3100S Series solves this by acting as an intelligent governor. By sensing discharge pressure and adjusting the motor’s frequency through the VFD, the controller ensures that the system pressure never exceeds the calibrated set point.
Specifications
Main Fire Pump Controller
The MarkIII+ FTA 3100S provides a variable frequency drive (VFD) to control the speed of a centrifugal pump for the purpose of limiting the system pressure in a sprinkler system used for fire protection. The controller shall control a fire pump motor having the horsepower, voltage, phase and frequency rating shown on the plans and drawings. The controller shall be equipped with both automatic and
manual bypass to start and run the motor should a problem arise with the VFD. The controller shall be provided with a full voltage starting bypass.
Standards, Listings & Approvals
The controller shall conform to all the requirements of the latest editions of:
NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection
NFPA 70, National Electrical Code.
The controller shall be listed by:
Underwriters Laboratories, Inc., in accordance with UL218, Standard for Fire Pump Controllers Canadian Standards Association CSA-C22.2, Standard for Industrial Control Equipment (cUL)
The controller shall be approved by:
Factory Mutual (IEC 62091)
Enclosure
The controller components shall be housed in a NEMA Type 12 (IEC IP54) drip-proof, floor mounted enclosure with powder coat finish. The enclosure shall include conductor entry gland plates, enclosure lifting brackets and lockable door.
