Product Information/Sales
Overview

Firetrol® Power Transfer Switches are available completely assembled with Firetrol Limited Service Fire Pump Controllers. The power transfer switches are built for use with generator set or 2nd utility use. The entire papckage of power transfer switch and controller is completely factory assembled, wired, tested, and shippepd as a complete unit for easy field connection to the power sources and the fire pump motor. They are available for 3 phase or single phase operation.

Firetrol power transfer switches are listed by Underwriters’ Laboratories, Inc., in accordance with UL218, Standard for Fire Pump Controllers; UL1008, Automatic Transfer Switches; UL508, Industrial Control Equipment and CSA, Standard for Industrial Control Equipment. They are built to meet or exceed the requirements of
the approving authorities as well as NEMA and the latest editions of NFPA 20, Installation of Centrifugal Fire Pumps, and NFPA 70, National Electrical Code.

Features

The following are included as standard with each transfer switch:

  • Thermal magnetic circuit breaker
  • 3-pole, double throw transfer switch mechanism, electrically operated, mechanically held
  • ASCO® Group 5 Control module providing for the following:
    -Door mounted operator interface panel with 4 line LCD display
    -In-phase monitor (3 phase operation)
    -Programmable engine exerciser
    -Transfer switch data logging
    -Differential voltage sensing on all phases of the normal power source
    -Voltage sensing of the emergency power source
    -Frequency sensing of the emergency power source
    -Transfer time delay to compensate for momentary power outages of the normal source
    -Retransfer from emergency to normal source is automatically delayed unless the emergency source fails
    -Cool-down timer for unloaded running of the generator set after retransfer to the normal power source
    -Instantaneous retransfer to normal if the emergency source fails and the normal source is available
    -3 second transfer restart delay to reduce current surges when transferring to or from the emergency source
    -NO and NC engine control contacts to start the generator set when the normal power source fails
  • Transfer Switch Normal LED
  • Transfer Switch Emergency LED
  • Emergency Isolating Switch Open LED
  • Test Selector Switch
  • Transfer By-pass Switch
  • Silence Alarm Pushbutton
  • Emergency Isolating Switch Open and Transfer Switch in Emergency Audible Alarms
