Electric Motor Fire Pump Controller

Name: Electric Motor Fire Pump Controller
Brand: Ayso Fire Protection

An electric motor fire pump controller is a full-service control unit that automatically starts the electric motor driving the fire pump when system pressure drops. Motor power, supply voltage and starting method are evaluated together when selecting an electric fire pump controller.

Tornatech GPx Series Electric Fire Pump Controllers

The Tornatech GPx series consists of models with different starting methods. The GPA is across-the-line, the GPY and GPW are wye-delta, the GPP is part winding, the GPR is autotransformer and the GPS is soft start/soft stop. This allows a model to be chosen to suit the motor power and the starting current capacity of the supply.

A 7″ ViZiTouch 2.1 touchscreen, simultaneous display of three-phase voltage and current, and a pressure and event recorder are standard on all models. The isolating switch and circuit breaker are operated by a single handle and mechanically interlocked with the door. A surge arrester, locked rotor protection, phase sequence indication and emergency start handle are also standard.

The controllers can be supplied with a GPU automatic transfer switch so that the pump can be powered from an alternate source during a mains failure. The GPx series is listed under UL 218 and FM Class 1321/1323 approved.

Frequently Asked Questions

Which starting method should be selected?

Selection depends on motor power, the supply's capacity to handle starting current and the project specification. The GPx series offers across-the-line, wye-delta, part winding, autotransformer and soft start options.

Are GPx controllers UL and FM approved?

Yes. GPx models are listed under UL 218 and FM Class 1321/1323 approved.

Is a transfer switch option available?

Yes. The controllers can be supplied with a GPU automatic power transfer switch.

In which ambient conditions does the controller operate?

It is designed as standard for 4 – 40 °C ambient temperature and 5 – 80% relative humidity. A 55 °C option is available. Controllers must be installed indoors.

What is the short-circuit withstand rating?

For the GPA model it is 100 kA at 200 – 480 V and 50 kA at 600 V. According to the brochure, higher ratings can be selected up to 150 HP.

What is monitored on the controller display?

Three-phase voltage and current, system pressure, motor status, starting transition, alarms and pump room temperature can be monitored.
