Scope
1.1 Products covered 1.1.1 These requirements cover controllers intended for starting and stopping centrifugal and positive displacement fire pumps, including automatic and non-automatic types for electric motor with or without transfer switch or engine driven pumps in accordance with Annex A, item 1. Types of controllers covered include diesel engine, electric motor, limited service, medium voltage and residential. Controllers may be suitable for use as service equipment. This equipment is for installation in non-hazardous locations in accordance with Annex A, item 2. 1.1.2 Controllers for electric motor driven, centrifugal fire pumps are intended for use with squirrel cage or wound rotor motors rated 600 V or less. Controllers for squirrel cage motors may be for across-the-line or reduced inrush current starting. Controllers may be provided with integral automatic transfer switches. 1.1.3 Variable speed fire pump controllers for electric motor driven, centrifugal fire pumps are intended for use with squirrel cage induction, inverter duty rated motors rated 600 V or less, and rated for 50 Hz or 60 Hz. 1.1.4 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. Controllers may be provided with integral automatic transfer switches. 1.1.5 Medium voltage fire pump controllers are intended for use with squirrel cage motors rated 601 V – 7.2 kV AC. 1.1.6 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 A. 1.1.7 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. 1.2 Products not covered 1.2.1 An automatic transfer switch intended to be used in fire pump circuits, that is provided separate from a controller.
