Low-voltage switchgear and controlgear - Controllers for drivers of stationary fire pumps

Scope

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 and stopping), alarms, signals, indicators, and the proper operation of battery chargers. The most significant purpose of this technical specification 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 technical specification, this procedure is described as the "fire pump controller test protocol". The object of this technical specification is to state the following: a) The unique characteristics of fire pump controllers, their associated equipment and their operational functions; b) The conditions with which fire pump controllers should comply with reference to 1) their construction; 2) their critical components including the mounting, arrangement, wiring and connections; 3) the degrees of protection provided by their enclosures; 4) their modes of actuation; 5) their operation and behaviour under normal, overload and short-circuit conditions; 6) their capability to annunciate significant events; 7) their electromagnetic compatibility for the environment into which they are placed; c) The tests intended for confirming that these conditions have been met, and the methods to be adopted for these tests; d) The information to be given with the equipment, or in the manufacturer's literature. In this context, this technical specification 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 technical specification. Referring to electric power sources, the requirements of this technical specification 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 technical specification do not apply to the method or means by which the electrical energy is generated nor to the installation between the origin of the installation and the fire pump controller, which are to be found in IEC 60364 series. This technical specification 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 technical specification, and b) for diesel engine fire pump controllers, d.c. batteries are the intended source of electrical control power.
