Preface:

This is the harmonized ANCE, CSA Group, and UL Standard for Low-Voltage Switchgear and Controlgear – Controllers for Drivers of Stationary Fire Pumps. It is the First edition of NMX-J-XXXX, CSA C22.2 No. 62091, and UL 62091.

This harmonized standard is based on IEC Publication 62091: First Edition, Low-voltage switchgear and controlgear – Controllers for drivers of stationary fire pumps, issued January 2007, and the requirements pertaining to fire pump controllers from the 2019 and past editions of NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection. This document is intended to replace NMX-J-626-ANCE-2015/UL 218/CSA C22.2 No. 263-15, published in September 2015, to provide globally accepted requirements for fire pump controllers. IEC 62091 is copyrighted by the IEC.

This harmonized standard was prepared by the Association of Standardization and Certification (ANCE), CSA Group, and Underwriters Laboratories Inc. (UL). The efforts and support of the Technical Harmonization Subcommittee, Fire Pump Controllers, CANENA THSC 121A-62091 on the Harmonization of Electrotechnical Standards of the Nations of the Americas (CANENA), are gratefully acknowledged.

This standard is considered suitable for use for conformity assessment within the stated scope of the standard.

The present Mexican Standard was reviewed and approved by the Comité de Normalización de la Asociación de Normalizacién y Certificación, A.C., CONANCE.

This standard was reviewed by the CSA Subcommittee on Fire Pump Controllers, under the jurisdiction of the CSA Technical Committee on Industrial Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the CSA Technical Committee. This standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.

Scope and object:

This International Standard applies to controllers intended for starting, controlling and stopping stationary fire pumps, including automatic and non-automatic types for alternating current electric motor or diesel engine-driven fire pumps. It is anticipated that a controller only controls a single driver.

Controllers for electric motor-driven fire pumps always include suitable short-circuit protection as an integral part of the controller. These controllers may include an integral power transfer switch. These controllers are rated 1 000 V a.c. maximum.

Controllers for diesel engine-driven fire pumps include electrical circuits that operate various control and supervisory functions, such as remote control (starting), alarms, signals, indicators, and the proper operation of battery chargers.

The most significant purpose of this standard is to characterize the unique features of fire pump controllers. A further purpose is to prescribe a procedure for exercising the controllers to verify that the unique features are operative. For the purpose of this standard, this procedure is described as the “fire pump controller test protocol”.

The object of this standard is to state the following:
a) the unique characteristics of fire pump controllers, their associated equipment and their operational functions;
b) the tests intended for confirming that these conditions have been met, and the methods to be adopted for these tests;
c) the information to be given with the equipment, or in the manufacturer’s literature.

In this context, this standard gives the requirements for all of the electrical functions associated with both the electric motor-driven and the diesel engine-driven fire pumps. Special applications such as explosive atmospheres, nuclear installations, ships, aircraft, etc. are not covered by this standard. Referring to electric power sources, the requirements of this standard apply only to the extent that they place limits on the nature, behaviour and characteristics of the electrical energy that is supplied to the service entrance (see IEC 60364-5-55).

The requirements of this standard apply neither to the method nor to the means by which the electrical energy is generated. In addition, they do not apply to the installation between the origin of the installation and the fire pump controller, which are to be found in the IEC 60364 series. This standard does not apply to diesel engine-driven electric generators which may be associated with a stationary fire pump installation.

EMC considerations are correlated with other IEC standards for similar products: a) for electric fire pump controllers, EMC considerations are covered by this standard, and b) for diesel engine fire pump controllers, d.c. batteries are the intended source of electrical control power.

1DV D2 Modification to Clause 1 by adding the following:

  • 1DV.1 This equipment includes limited service and medium voltage. Controllers may be suitable for use as service equipment. This equipment is for installation in non-hazardous locations in accordance with Annex DVA, item 2.
  • 1DV.2 Controllers for electric motor driven, centrifugal fire pumps and positive displacement pumps are intended for use with squirrel cage or wound rotor motors. Controllers for squirrel cage motors may be for across-the-line or reduced inrush current starting.
  • 1DV.3 Variable speed fire pump controllers for electric motor driven, centrifugal fire pumps and positive displacement pumps are intended for use with squirrel cage induction, inverter duty rated, motors, and rated for 50 Hz or 60 Hz.
  • 1DV.4 Limited service controllers are intended for across-the-line starting of squirrel cage motors rated 22 kW (30 hp) or less, 600 V or less.
  • 1DV.5 Medium voltage fire pump controllers are intended for use with squirrel cage motors rated 601 V – 7.2 kV AC.
  • 1DV.6 Residential fire pump controllers are intended for use with single-phase squirrel cage motors rated 240 V or less. Residential fire pump controllers are intended to be used in one or two family dwelling units in accordance with the requirements of item 35 in Annex DVA.
  • 1DV.7 Diesel engine fire pump controllers rated nominal 24 V DC or less are intended for use with fire pump engines. Where required, AC Voltage is limited to 600 V AC or less.
  • 1DV.8 An automatic transfer switch intended to be used in fire pump circuits, and that is provided separate from a controller, is covered by the requirements of item 11, Annex DVA.
