- Scope
- Scope and purpose This International Standard applies to control devices intended for starting, controlling and stopping stationary fire pumps, including automatic and non-automatic types of engine-driven fire pumps electric alternating current or by a diesel engine. It is agreed that a control device only controls a single drive. Control devices for fire pumps driven by an electric motor always include, as an integral part of the control device, suitable protection against short circuits. These control devices may include an integral power transfer switch. The maximum rated voltage of these control devices is 1000 V alternating current. Diesel engine driven fire pump control devices include electrical circuits that provide various controls and supervisory functions such as remote control (starting), alarms, signals, indicators and correct operation of chargers battery. The most significant objective of this standard is to characterize the specifics of fire pump control devices. An additional objective is to prescribe a procedure for calling on control devices to verify that the specifics are operational. For the purposes of this standard, this procedure is described as the “test procedure for fire pump control devices”. The purpose of this standard is to establish the following: a) the specific characteristics of fire pump control devices, their associated equipment and their operational functions; (b) the tests intended to confirm that these conditions have been satisfied and the methods to be adopted for these tests; c) the information to be given with the equipment or in the manufacturer's documentation. In this context, this standard gives the requirements for all electrical functions associated with fire pumps driven by both an electric motor and a diesel engine. Special applications such as potentially explosive atmospheres, nuclear installations, ships, aircraft, etc. are not covered by this standard. For electrical power sources, the requirements of this standard apply only to the extent that they set limits on the nature, behavior and characteristics of the electrical energy that is supplied to the input (see IEC 60364-5-55). The requirements of this standard do not apply to the method or means of supplying electrical energy. In addition, they do not apply to the installation between the origin of the installation and the fire pump control device which is covered in the IEC 60364 series. This standard does not apply to electric generators driven by a diesel engine which can be associated with a fixed fire pump installation. EMC considerations are relevant to other IEC standards covering similar products: a) for electric fire pump control devices, EMC considerations are covered by this standard, and b) for devices When controlling diesel-powered fire pumps, DC batteries are the intended source of electrical power.
